Our base for the abrasive layer convergence , and in the use with flange firmlyabrasive grinding wheels held on the grinding machine spindle. Suri outside environment as more rounded shape . There is not a diamond wheel diamond production from. It may be divided into three layers , i.e. task layer , substrate buffer layer . As long as the task layer is called the diamond layer , the abrasive agent and filler compact form seems like a diamond determines its inability to do4 inch saw blades tough . The buffer layer and the substrate are non-diamond layer . Even as a diamond wheel roots sand arrived with its most empty thinking is to see the consistent use of abrasive materials . Its primary organs are made of metal powder, resin powder , ceramic and metal plating as liaison agent. How the diamond wheel three disjointed comprehensive alone. If the corporate team as it tastes good Qianan three choices of diamond grinding wheel diamond place.

Diamond saw blade grinding requires excellent technical

There are many small factories saw blade grinding , hand workshops on the market now ; grinding only the serrated blade rake angle , a simple rough treatment, after treatment has changed the original blade angle , the blade angle , side angle , and tooth room is simply not deal with the conditions , do not be detected , correction of its processed products after grinding .

 Grinding time is longer , etc., make a note to tell you about our grinding process testing process , and related technical standards.

 A. Upon receipt of our customers need grinding blade , first of all, build customer product files , put all the blade 50 degrees Celsius warm water and soak for 30 minutes, then wash , rust, binding preliminary processing visual inspection, the obvious defects can not be abrasive products, good customer numbers marked after cleaning , but  tile cutting blades the area directly put back until after the product is completed with grinding required to the customer .

B. Then the angle with the dial gauge testing, including tooth rake angle ; hind ; side angle detection ( see no cracks , chipping , etc. ) , and then put on the projector to enlarge 50-100 times to determine the original angle serrated blade wear ; If the tooth chipping small , we can improve the grinding appropriate amount to reduce production costs.

 C. If you have alloy teeth need to be replaced , use of automatic welding machine for gear tooth exchange operations. D. Next, correction for blade stress , this step is critical blade grinding step ; requires highly experienced technicians to the completion of the diamond blade during high speed operation , the external force, the stress in the blade has been changed , it will appear saws Road bigger ; surface roughness phenomena ; we stress adjustment requires two more times ; If you can correct cutting discs  the standard range , then into the next process , on the contrary , we will contact the customer to solicit customer feedback, customer requirements as grinding, we are precision grinding, however , after the completion of the package , we will blade , diamond saw blade attached deviation specific data. We first used Japanese imports 200 grinding diamond wheel for coarse grinding particle size , particle size and then use the 600 wheel for precision grinding.

  E. Next check the vibration rate , after passing by the B -step process , final inspection, shipment region after placing fully qualified , work orders by businesses to complete the polishing process .

 Under such strict procedures , our sanding discs  products will ultimately into the hands of customers , in this sense , our products are definitely stand the test of time.

Matters related to the use of the saw blade

Precautions blade using:
 1 Keep alloy saw hanging vertically on the drying rack, be sure to avoid damp places, do not alloy blade flat on the floor or shelf, flat lead alloy blade deformation.
2 When using, do not exceed the  abrasive flap wheels specified maximum speed. After the speed of calculation is attached for reference.
3 When used, must be with shields, gloves, helmets, safety shoes, safety glasses.
4 When installing alloy saw blade, you must first confirm the performance of the saw table, uses, it is best to read the manual saw table. Avoid loading the wrong, causing an accident.
5 When installing alloy blade, alloy blades must first check whether there is a split, distort, fill level, after the  masonry drill bits fall of teeth and other phenomena, then install it.
 6 super-hard alloy saw sharp serrated prohibit collision, falling to the ground, must be gently.
7 After loading alloy blade, you must confirm the center hole of the blade is firmly fixed on the saw table flange, gasket must be good washer; then gently push the hand saw blade confirmation piece rotation is eccentric shaking. 8 alloy blade must cut direction indicated by the diamond bandsaw blades  arrow is aligned with the direction of rotation of the saw table. Do not install the opposite direction, installed the wrong direction can cause tooth out.
 9 preroll time: After replacing the alloy saw blade, before use pre-turn for a minute, let the saw table to enter the work state, to be cut.

ultra-high speed grinding occupy undisputed dominance

1, the plating process is simple, easy to manufacture, less investment;
2, easy to use, no dressing;3, single-layer structure determines it can reach very high operating speed, the stone drill bits  current foreign countries have been as high as 250 ~ 300m / s; 4, although only a single layer of diamond, but there is still sufficient lifetime; 5, for high precision roller wheels, electroplated unique manufacturing method.Because of these advantages, electroplated grinding wheel speed, ultra-high speed grinding occupy undisputed dominance. Electroplated diamond grinding wheel defects exist: the coating and the substrate and the metal surface stone polishing pads  is not kept firmly binding the abrasive chemical metallurgical bonding, actually only be mechanically entrapped abrasive coating metal inlay, thus gripping force is small, efficient grinding diamond particles heavier load and easyOff (or plating flaking) and lead to an overall failure; gripping force to increase the coating thickness must be increased, and the results highly abrasive bare chip space is reduced, wheel prone to clogging, the cooling effect is poor, prone to burn the workpiece surface. CurrentlyDomestic  concrete saws electroplated grinding wheel manufacturing has not been achieved by optimized processing conditions required to design the best grinding wheel topography, single electroplated diamond grinding these inherent drawbacks will be significantly limited its efficient grinding applications.

the depth is involved in diamond cutting wear

( 1 ) diamond saw blade speed: in practical work , diamond saw blade line speed is equipment conditions , and is limited to the quality of the blade sawing stone before nature. From the best blade life and cutting efficiency , the linear velocity of the blade should be selected according to the different nature of the stone . When cutting granite , the blade may be within the selected line speed 25m ~ 35m / s range. For high quartz content and difficult cutting granite , remove the saw blade line speed limit diamond bandsaw blades  is appropriate. In the production of granite tiles, use a smaller diameter diamond saw blades , wire speed can reach 35m / s.
( 2 ) cutting depth : the depth is involved in diamond cutting wear , effectively sawing , saw the forces and the nature of the important parameters are affected by sawing stone . In general , when a high line speed diamond saw blade should be selected for cutting of small depth , from the current technology , the cutting depth of the diamond can choose between 1mm ~ 10mm . Usually large diameter saw blade when cutting granite blocks , cutting depth  turbo diamond blade can be controlled within 1mm ~ 2mm between the feed rate should be reduced at the same time . When a large diamond saw blade line speed , you should select a large depth of cut. But in performance and tool strength saw the extent permitted , should try to take a greater concentration of cutting cutting to improve cutting efficiency. When the surface of the processing requirements of a small depth of cut should be used . ( 3 ) diamond saw blade feed rate : Feed rate Jibei sawing stone feed rate. Its size affect the rate of cutting , the blade and the cutting force by the heat dissipation area . Its value should be based on the nature of the stone sawing selected . In general, the sawing softer stone, such as marble, may be appropriate to increase the feed rate, if the feed rate is too low , more conducive to improving cutting rates. Sawing fine structure , relatively homogeneous granite , may be appropriate to increase the feed rate, if the feed rate is too low , diamond blade easily cutting discs  be polished . But while sawing UNEVEN coarse structure of granite , feed rate should be reduced , otherwise it will cause the blade vibration resulting in reduced fragmentation of diamond cutting rates. Granite cutting feed rate is generally within the range of the selected 9m ~ 12m/min .

Factors Affecting the efficiency and lifetime of diamond saw blades

Factors affecting the efficiency and life of the diamond saw with particle size , concentration, binding agent , and the hardness of the diamond sawing process parameters and the like . It has cut the number of blades can be wire-speed , cutting feed rate and concentration .
First, the cutting parameters:
( 1 ) Blade Speed: In practice , the  diamond cup grinding wheel line speed diamond saw blade being equipment conditions , and restrictions were sawing blade quality stone before nature. From the best blade life and cutting efficiency , the linear velocity of the blade should be selected according to the different nature of the stone . When cutting granite , the blade may be within the selected line speed 25m ~ 35m / s range. For high quartz content and difficult cutting granite , remove the saw blade line speed limit is appropriate. In the production of granite tiles, using a diamond saw blade smaller diameter , the line speed up to 35m / s.

Three main diamond cutting tool materials

Three main diamond cutting tool materials --- PCD, CVD synthetic single crystal diamond thick and performance comparison results: PCD welding, mechanical grinding and the highest fracture toughness, wear resistance and edge quality centered, worst corrosion  cbn grinding wheels resistance; CVD thick best corrosion resistance, mechanical grinding resistance, edge quality, fracture toughness and abrasion resistance centered weldability worst; synthetic single crystal diamond cutting edge quality, anti- the best wear resistance and corrosion resistance, weldability, mechanical cutting resistance and fracture toughness of the worst. Currently, high-speed cutting diamond tool (2500 ~ 5000m / min) aluminum an ideal tool material, but in the high-speed cutting steel and steel alloys Shique wear faster, the wear mechanism was mainly due to carbon and iron with greater affinity effect, especially at high temperatures the diamond easily react with the iron, so it is not suitable for cutting steel and its alloys.
We have zero defect management  fibre discs concept, through consistently. All along, the pursuit of perfect quality, it is also constantly improve the service system, care for your every need, through a sales and service network throughout the country to provide you with professional services. Diamond tool material is divided into single-crystal diamond (there are two kinds of natural and man-made, natural single crystal diamond expensive part is single crystal synthetic diamond substitute), synthetic polycrystalline diamond (PCD) and synthetic polycrystalline diamond and carbide composite blade (PCD / CC) and CVD diamond.
Single crystal diamond
Single crystal diamond cutting tool must be  sds hammer drill bits used for large particles (mass greater than 0.1g, the best path length not less than 3mm), mainly used in surface roughness, geometry, high precision and dimensional accuracy requirements of precision and ultra precision machining applications fields.

Inner circle grinding mechanical transmission

 Inner circle grinding is generally divided into four types: wind-driven inner circle grinding, high-speed electric aerostatic bearing inner circle grinding, mechanical drive and electric grinding inner circle inner circle grinding.Wind-driven inner circle grinding: spindle with  concrete saw blades  a turbine driven by compressed air turbine rotates the spindle speed, spindle speed reaches 10000R/MIN. Moreover, small vibration, pressure can be adjusted stepless. And with regulators, filters and other accessories.Aerostatic bearing speed electric grinding inner circle: The aerostatic bearing (supply pressure is 40 ~ 65MPa), grinding system rigidity, both electric grinding characteristics, speed up 180000R/MIN, suitable for grinding a ~ 10MM hole.Inner circle grinding mechanical transmission: mainly by the spindle, bearings, sleeve body shell, flat supporting pulleys and other components. Then, after replacement of the long axis, is used to grind different bore diameter and  granite polishing pads length, for comparison, the use of low speed, the speed is generally lower than 2000R/MIN.Electric grinding inner circle: A three-phase asynchronous motor direct drive, and another by a high-frequency electric motor driven spindle speed of up to 50000 ~ 90000R/MIN. Output power is larger, instantaneous overload, speed characteristics hard, little vibration.enerally the heat generated by the grinding process will burn the workpiece, so you need to use coolant to promptly take the heat, this is called wet. However, grinding tools is a special application, as part of more complex shape, machining accuracy is relatively high, most of the processes set by manually, there is no way to use wet methods. In theory, the hardness of steel molds are high, and SG monocrystalline corundum grinding wheel is the best option.

monocrystalline diamond tool application

the crystal structure of the highest density of metal atom such as axial face-centered cubic crystal. Diamond crystal connected between the carbon atoms bond to sp3 hybridized covalent bond, with a strong binding force, stability and direction. The unique crystal structure of diamond in nature it has the highest hardness, stiffness, refractive index and thermal conductivity, and high wear resistance, corrosion resistance and core drill bits  chemical stability.
Excellent characteristics of single crystal diamond meet the precision and ultra-precision cutting tool material for most of the requirements and is ideal for precision cutting tool materials. Diamond without internal grain boundaries uniform crystal structure so that the tool cutting edge can theoretically reach the atomic level flatness and  core bits for concrete sharpness, cut thin cutting ability, high precision, cutting force is small; their high hardness and good wear resistance resistance, corrosion resistance and chemical stability can ensure that the tool has a long life, so that it can continue for a long time of cutting, the tool wear can be reduced because of the precision of the parts; its high thermal conductivity can  cbn grinding wheels be reduced and the cutting temperature parts thermal deformation.
Single crystal diamond tool in the machining field has an important position, is widely used as a mirror, missiles and rockets navigation gyro, computer hard disk substrate accelerator electron gun, such as ultra precision mirror of parts. Can also be used in the manufacture of single crystal diamond eye, brain surgeon's scalpel, thin slicing knives and other bio-medical tools.

the circular blade in operation when beating deal

First, the circular blade in operation when beating deal?
Circular blade in operation when beating Processing Processing Cheats: Check the circular blade installation is in place; inspection work cut foot mounting surface if there is debris; checking the gap between the inner diameter of the rotating shaft.
Second, the circular blade crack how to do?
How do deal with circular blade crack Cheats: Before use, finger fingers hooked blade gently with a wooden hammer to knock several times, listening to the sound; after use: When installing the  mounting surface can exist due to hard objects, fixed blade cracked when the force wood drill bits  resulting ; addition to the above two cases, can break due to human or blade itself is a problem.
Third, the circular blade blade nicked how to do?
Nicked circular blade blade handle Cheats: cut legs for five minutes without idling and began to work; component foot diameter is too large, you can adjust the angle of blade to handle specific angles according to the diameter to the size of the foot elements.
Fourth, continue to cut feet  wet polishing pad circular blade element how do?
Circular blade components continue to deal with the foot cut Cheats: whole foot or part of PCB components clearly score, check the PCB thickness and material, whether due to high temperature during welding deformation caused by PCB; tracks with adjustable blade gap distance smaller; whether Yuan blade used for too long, there were minor gaps without grinding.Circular blade to achieve a cost-effective application of the coating may depend on many factors, but for each specific processing applications, usually brick saw blades  only one or several circular blade coating viable options. Circular blade coating and its properties are correct choice could mean significantly improved processing performance with almost no improvement between the two. Depth of cut, cutting speed and coolant are likely to circular blade tool coating application effect of impact.
Since the processing of the workpiece material in one kind, there are many variables, so selection of the circular blade coating to determine the best ways is through trial cut. Coating suppliers are constantly developing more new circular blade

Monolayer brazing diamond wheel introduction of some of the major

Using scanning electron microscopy showed white gold diamond silver wrapping around , X-ray diffraction analysis confirmed Cr3C2 generation, this carbide layer is achieved Diamond
Stone and steel substrate bonding strength between higher . Diamond grinding experiments also confirmed that tile saw blade  there will grip strength, high temperature brazing monolayer diamond grinding wheel life and grinding efficiency than electroplated sand
Wheel has been significantly improved . Monolayer coating high temperature brazing diamond diamond wheel as poor thermal stability , 800 ℃ when the transition occurs graphite , so the higher soldering temperatures will inevitably lead to
Leaving diamond diamond intensity decreased thermal damage ; while binders harmful elements make diamond graphitization corrosion , it can be coated with a layer of diamond surface active metal
And then brazing alloys . Abrasive plating techniques include chemical vapor deposition, ion plating, thermal evaporation , vacuum evaporation plating such as micro- chemical vapor deposition Cr, Ti, vacuum micro evaporation plating can improve the surface properties of diamond . Brazing process , mediated by virtue of the role of the coating , in addition to diamond and easier to achieve strong metallurgical bond between the chemical bonding , the hot air as an oxygen barrier coating on leaving the role of carbon atoms in the diamond surface reacts with oxygen speed is greatly reduced, while strong carbide forming coating elements and diamond surface carbon atoms react carbide , closed diamond surface dangling bonds , increasing the oxidation resistance , thus inhibiting binding agent Fe, Co, Ni and other elements of the diamond itself, graphitization of diamond etching process, so that after brazing still maintain the original strength of the abrasive grain type . Brazing steel substrate when the first plating layer is pre- Ni-P alloy ( melting point 880 ℃), and the arrangement of the diamond film on the alloy layer , 1050 ℃ argon brazing 5min, then cooled to room temperature. Grinding tests dry core drill bits showed that the diamond coating and binding agent as a good wettability , and effectively avoid the grit off, greatly improves the performance of the grinding wheel , to achieve a substantial increase in processing efficiency wheel life .
It should be pointed out that as the diamond coating and binding agent between the deposit with adaptability , so only suitable binder coating process to make optimum physical and mechanical properties of diamond . Single high temperature brazing problems and countermeasures wheel kept at home and abroad wheel of high temperature brazing monolayer Although achieved good results , but its manufacturing process needs to be further improved. Currently retained, mainly as follows: one in what brazing process to produce the diamond bonding interface bonding strength with high chemical diamond polishing pads  metallurgical bonding ; two suitable binding agent layer thickness and uniformity control ; three abrasive reasonable and orderly arrangement . For improving the bonding strength of the diamond and the brazing material , its key diamond brazing , brazing material between the metal substrate to produce three chemical metallurgical bonding , the solder alloy should contain a strong carbide forming elements ( such as Ti, Cr, V, etc. ) , and to seek lower temperature brazing of diamond to minimize the damage. Before brazing filler metal abrasive orderly arrangement to improve the consistency of thick cloth after brazing binder layer thickness uniformity is also very important. Work surface with abrasive wheel arrangement reasonably abrasive industry has been committed to the pursuit target , and is expected to achieve single grinding wheel .

Bit matrix performance design

Based on these two points, bit matrix performance design should include

steel bonded carbide type carcass composition and its properties. Type

of steel bonded carbide matrix diamond drill design and research, in

order to replace most of the metal grinding wheel  tungsten carbide alloy, based on a certain

amount of nickel, cobalt, manganese, titanium, chromium, molybdenum and

other materials, and rare earth elements in hot conditions with the

formation of a certain hardness, wear resistance and can be securely

appropriate package insert diamond steel bonded carbide matrix [1]. We

focus on the matrix hardness, wear resistance and firmness diamond bezel

setting. Type of steel bonded carbide matrix material, you also need a

certain amount of phosphorous alloy material to replace part of pure

iron. Adding phosphorus alloy aims to reduce the sintering temperature

and increase the performance of the carcass brittle [3], and in favor of

a diamond blade in the matrix to improve the drilling time. In order to

control the phosphorus content in the matrix, in addition to a

phosphorus alloy powder, the pure iron carbonyl must join to control the

phosphorus content and improving the performance of the carcass. 1.2

steel bonded carbide type carcass test: For hard and compact rock

characteristics, drilling practices and  diamond polishing pads preliminary studies indicate

that the matrix hardness to diamond drill HRB108 ~ HRB115 more

appropriate, the wear amount of lower-middle (260 mg ~ 370 mg) is ideal.

Steel bonded carbide type carcass preliminary trials have shown that in

order to achieve these targets, the carcass of the basic formula is as

follows: P 2 iron content of 40% to 48%, as a binder metal content of

26% tin bronze ~ 32% tungsten content of 12% ~ 28%, Ni content of 5% to

10%, the cobalt content of 3% to 7%, and the remaining ingredients are

titanium, manganese, molybdenum, chromium, and rare earth. According to

this basic ratio, the sintering process in a reasonable condition,

carcass materials and manufactured diamond drill has better adaptability

and drilling results. Process for hot carcass performance will have a

significant impact, which obviously affect the sintering temperature and

pressure [4]. Therefore, in the diamond blades  study of steel bonded carbide matrix,

sintering temperature and pressure must be incorporated into the design

factors. Iron at high temperatures the diamond has some heat damage, it

should be shortened by rapid sintering and holding time. In this test,

the sintering process is designed to: sintering temperature 960 ℃,

pressure parameters 16 MPa, holding time 4 min. Sintering in SM1002A

carcass type resistance furnace controlled intelligent. The combination

of hot-pressing process is the result of many experiments and analysis

finalized, so it is reasonable. According to the above-mentioned range

of carcass composition and sintering processes, uniform design

experiments to study the carcass composition of steel bonded carbide

type changes on the carcass performance were investigated. In accordance

with the uniform design method, the experimental design of the 16 matrix

formula combinations in Table 1. Select the matrix hardness and wear

resistance properties of the target for the carcass. Matrix hardness

testing using HR - 150A Rockwell hardness tester, and select HRB as

measured values, for each combination of two samples of prototype

formulations, both sides of the direction of the pressure measured

twice, 8 hardness data were measured, taking Examples of the formulation

the average hardness value....

diamond tool manufacturing process

We usually for cooking or cut fruit is most commonly used tool, the tool is also very many, just as we buy a knife when the boss asked us to buy the same good or bad, diamond tool we often use the  masonry saw blades  following Matsuno Tool Ltd. of Shenzhen City to talk about the diamond tool manufacturing process and cost.As the particularity of valve seat material, tool wear quickly, consumption, production costs are higher. If the area can reduce the processing costs of processing costs for the control of the engine has a certain significance. Reduce production costs of the tool approach:
First, the design of the new tool:
1, Design: the design of the tool's basic idea is that the structure should be simple in order to reduce the production costs of the tool; tool regrinding can increase the number and improve the overall life of the tool, the tool in order to achieve lower consumption costs. Through two aspects of this tool to achieve this goal.

3, the tool structure: the structure of the tool shown in Figure. Three long blades 1,2,3 strip fixed to the blade by a compact body, the axial dimension of the blade to be adjusted by adjusting the screw. The radial dimension of the blade without adjustment. Therefore, this tool presetting is simple. Bore FD can be used to install the  construction tools  valve guide reamer to achieve valve seats and valve guides processed simultaneously.
Blade resharpening Precautions:
1, using the grinding fluid to prevent tool durability reduced.
2, the tool grinder with sufficient rigidity. Tool grinder to meet domestic requirements.
3, edge straightness must be controlled at 0.01/100 or less. Straightness below standard will cause valve seat leakage.
4, using a particle size of # 600 diamond grinding wheel. The size of the blade wheel is easy to meet the requirements of straightness and roughness.

What are the current market and diamond tools

 At present, China's use of abrasive machining, geology drill and stone cutting

formed, standardization, variety specification is complete, stable product

quality, some products in the  hss drill bits international market certain competitiveness. All

kinds of diamond tools also been widely used in various industries, and

achieved significant economic benefits, but on the whole diamond tools

industry, still need to improve the industrial planning, broaden application

areas, creating an international brand.
1 Industry Planning: strengthen macro-control management
Because the blind development, hardware and tools, especially diamond tools

production layout appears scattered and chaotic situation everywhere, generally

small-scale producers, production is not centralized, process technology, the

lack of market competitiveness, product quality tools sales market instability,

competition disorder, price confusion, economic efficiency is not high.
(2) Product Development: Widening the application areas of diamond

diamond electroplated tools of new technology

Diamond is found in the highest hardness, sharp with good abrasive. The method

of electroplating diamond abrasive "plating out" on the metal base, instead of

the  diamond saw blade  traditional casting sintering, not less investment, low cost, and avoid the

oxidation of the  diamond under high temperature conditions, to ensure the

hardness and sharpness of diamond.
Diamond in the whole process, the plating layer with more than 90% is due to

poor due to poor plating pre-treatment. Therefore, to improve plating quality,

the most important thing is to do pre-plated.
Pre-treatment of the general content include: degreasing, rust, etching,

pickling, cleaning and activation plus auxiliary electrode and fitted pegs.
In order to improve the coating quality, after the electroplating industry at

home and abroad were analyzed and compared with the actual, developed a new

treatment before plating process is as follows: deburring cleaning coating

thermal insulating plastic scrub chemical degreasing, pickling cold water cold

water electricity Chemical degreasing washing anodized flushed into the slot.
1 with sandpaper and hand deburring file to remove burrs on the workpiece, to

prevent the workpiece surface showing dielectric bad state.
(2) The workpiece cleaning with alcohol scrub again, initially cleared the

surface of the oil.
3 plastic insulation coating the  masonry saw blades  workpiece after the scrub, in the non-plated

parts coated with a layer rapid adhesive coated parts of the non-insulated.
4 To prevent the need to scrub plated parts are coated with plastic insulation,

hand file or sandpaper to polish the parts and then again, and then rinse.
5. Chemical degreasing degreasing formulations.
Sodium hydroxide has a strong saponification, and animal and vegetable oils

reacts fly soluble soap and glycerin. THF is a surface active agent call in its

hydrophobic group and a dodecyl sulfate synergy hydrophilic groups should,

lowering the liquid and the surface tension between the work. It acts as a

caustic additive accelerated degreasing speed. Sodium carbonate and sodium

silicate to place relative to the two buffer from the buffer to the acid, the

PH value of the melt remain substantially edges. The workpiece is set with the

above solution at 40 ℃ ~ 60 ℃ case of cleaning for about 30 minutes.
6 hot, cold rinse first with hot water, rinse with cold book, to avoid oil into

the acid solution in addition.
7 pickling acid liquid formulation, its purpose is to remove the oxide surface

of the substrate.
8 cold water after pickling, the workpiece clip out, rinse with cold water, and

then loaded linked to the electrochemical degreasing tank.
9 spark electrochemical degreasing degreasing formulations school
The work clothes hanging in the cbn grinding wheels  solution, the connection with the point source,

the first cathode for 1 minute, 3 minutes and then anodized. The current

density used 10A/dm2, an electrode of stainless steel plate. Degreasing

electrochemical reactions are as follows:
Anode degreasing: 4OH - 2e = O2 + H2O
Cathodic degreasing: 2H + +2 e = H2
Very tired after using the first female co-degreasing method, with degreasing

speed, no hydrogen embrittlement advantages.
10 Rinse the workpiece after electrochemical degreasing sexual activity with a

book rushed into thin wash, prepare hast yang line processing.
11 anodized
Anodizing liquid formulations shown in Table 4, the substrate is mounted hung,

to be inserted into the fluid-plated parts. A negative electrode lead, the

positive electrode substrate. Current density of 25A/dm2, is applied for 3

minutes. Anodized avoid hydrogen embrittlement phenomenon, especially for the

last one into the groove before the procedure.
12. Rinsed into the slot of the anode substrate processed quickly rinsed, into

the plating tank, ready to plating.
This completes the entire diamond plating plating pre-treatment.
(Two) results
The specimen divided into five experimental groups, at various pre-plating

process under the pre-plating, and electroplating in the same plating

conditions into the slot. Specimens of each group specific treatment

conditions.
Specimen using 15152mm2 iron tablets. Experiment, the temperature was 40 ℃ 1

℃, the current density is 40MA/dm2, the anode 2 is pure nickel plate, cathode

specimen.
After the plating adhesion test pieces for both test and brittleness. Coating

adhesion test is a qualitative assay method using the rasp test. The so-called

experimental method refers rasp rasp coating from the substrate to the coating

direction 45o filing edges. If coating is not to be brought up or fall off, was

qualified.
When the binding is good, then the coating brittleness test. Brittle bending

test is used. Bending the specimen caught in the vise repeated bending, but

with a magnifying glass to observe the changes appear curved parts of the first

crack so far.
Table 5 shows the measurement results, the use of new technology, the specimen

surface smooth and good, grease and oxide are Ex, specimen showing a good state

by plating. Coating metal and the substrate has good adhesion between the

metal, coating uniformity, are better integrity.
(Three) Conclusion
1 mechanical deburring, rasp-plated parts required methods to prevent the

workpiece surface showing the bad state of the dielectric;
(2) the sodium dodecyl sulfate as a base additive to enhance the activity of

the matrix surface, to the oil rate, good quality;
3 using low temperature to the oil, so that the substrate from heat stress;
4, after the chemical degreasing and pickling, and by electrochemical

degreasing and anodizing, greatly changed the state of the substrate surface to

improve the dispersibility of the bath and covering ability to improve the

uniformity of the coating, integrity enhance the coating adhesion.
