How to identify and saw the matrix do good piece burr cut big reason

Saw the matrix to identify how to do: Use a permanent marker to make the hole in the middle of the blade near the logo, after the device has a flange on the blocked will not be erased; using laser GUSHI core bits for concrete  marking, such as fast peerless blade; most good is pneumatic marking. Hot rolled plate (plate oil must deformation) material production, saw tooth after punching hole and made a good fly how to remove the burr hole around the edges and tooth equipment and the way equipment with the center point of grinding (also called the hole grinder) it? Using simple equipment on bench below to make a base fixed. Tooth points glitches, buy a serrated grinding machine or by hand with a look. Why aluminum blade cut piece burr is always king, get a new blade also has a glitch, there is some kerf side has no burr burr side?
  There are two effects:
  Material: Soft hardness usually aluminum sawing down after glitches obvious, so you aluminum materials and state is not too soft
 Sawing question: blade and cutting speed, cutting equipment usually used between 5000-6000 rpm, the problem is generally GISHI concrete diamond blades  estimated that the blade is a 9-inch alloy saw Bosch ,60-70 yuan a piece, very durable Gold Fields is also available. Of course, if the condition can also buy Bosch circular saws, one to be in the vicinity of 1,000 yuan, 2100kw Bosch's encroachment up pretty good, at least much better than Rui Qi. Of course, you can also choose metal band sawing machine sawing advantage of small incision, less waste, while the cut is not as smooth, the disadvantage is the high price band, a small range of processing.

Analysis method of diamond grinding wheel cutting wheel

Here today for me to introduce to you a brief analysis about the method of diamond grinding wheel cutting attention to detail the relevant information , I hope to help you in the future when masonry drill bits  you can buy some used, please follow the small series together to look at the contents of the following describes it !
A grinding wheel in the Leads chipping is easy : with a larger angle of the main cutting tool grinding wheel , cut entry provenance easy to chipping . To solve this problem , using a circular blade , changing the main angle , so that the Leads stable. The feed amount of 1 ~ 1.5mm case chipping phenomenon did not occur .
Second, the chip in powder form : Cutting wheel chips in powder form , in the form of tool wear is flank wear , mainly exposed diamond grinding wheel abrasive wear.
Third, the cutting force and the cutting temperature is low : diamond composite sheet has a high thermal conductivity  4 inch circular saw blade of tungsten carbide 1.5 to 9 times , the copper 2 to 6 times , the cutting zone temperature quickly spread . Thus, PDC cutter cutting resin bond or ceramic bonded grinding wheel temperature , many times lower than the cutting of metal . Fourth, with the traditional turning tools, diamond composite sheet in the process of turning almost no dust fly, also able to effectively reduce the noise , diamond wheels to further improve the working environment is conducive to worker health.
 Second, we have to consider is the size of choice, when you want to select coarse grained diamond wheels and vice versa , when faced with ultra- fine grinding wheel to use powder .

For special non-standard tool drilling

Currently, a variety of large composite fastener holes required in the processing more, the machine becomes more and more of a challenge and complexity of a large number of deep hole machining. These are two completely different application areas, but the common denominator is carbide tipped saw blade  processed in order to obtain satisfactory results and competitive processing performance, you must use the customization tool.
Non-standard tool is ideal for cutting the parts completely or partially cutting tool is based on the concept has been proven standards such as the existing blade clamping device, shank and interfaces; it might be equipped with multiple criteria a dedicated blade holder, can be used as two or more standard tool usage; also be a special cemented carbide material and / or channel made of indexable inserts, the use of maximum efficiency, and to provide a longer, more stable tool life. Associated with non-standard tool also includes incomplete standards, as an alternative to standard tool with a very small deviation characteristics.
When you need to process more complex parts, the part of the various features require specialized non-standard tool solutions. This also applies to the processing of simple parts, because the non-standard solutions can eliminate production bottlenecks encountered. The non-standard tools as the best solution for many occasions, including most  cutting blades of the machining range, materials and type of industry, which is the most representative of most of the non-standard tool modular tooling solutions. These solutions are usually based on criteria such as blades, knife cards, tool interfaces, flute, anti-vibration system or tool holder clamping device based on various combinations. With unique properties accounted for purely non-standard tool nearly a quarter of the total number of non-standard tools, and similar to the standard tool for non-standard tools accounted for three quarters.
Processing areas of processing and deep parts made of composite material is that the main processing of the use of non-standard tool places, such composite materials are mainly carbon fiber ring saw blades  reinforced plastic (CFRP), and by stacking the metal support of the composite material of the material.
Deep processing is widely used in a variety of industries, most notably in the energy industry and the aviation industry. Some deep parts are usually difficult to process or that seem difficult to begin processing, but the use of non-standard custom tooling solutions can, through an efficient and secure way to easily solve this problem.

three lines cut into the feed grinding wheel

This method machine adjustment and wheel dressing more convenient, radial cutting force is small, the workpiece thermal conditions are good, high precision machining, grinding acme screw up to three (JB/T2886-1992) highest accuracy, the surface roughness 0.2 to 0.4 microns. You can screw up a different angle grinding, teeth opened a different, a different aspect ratio of the workpiece, suitable for processing a variety  PCD grinding wheel of precision thread and ball screw, but the production is less efficient than multi-line grinding wheel, commonly used in single-piece, small-batch production.Over 2 wire feed grinding wheel vertical As a multi-line grinding of the cutting comb teeth also participate can be completed in a single pass of the workpiece grinding, high production efficiency, but is difficult molding wheel dressing, the large pitch, a large helix angle of the thread and the teeth shaped high precision thread should not be used, suitable for carbide grinding wheels  mass production of grinding teeth is simple, lower-precision thread.
 More than three lines cut into the feed grinding wheel
 This method is suitable for grinding small pitch, small thread lead angle, low precision and stubby threaded parts, and on the threaded grinding wheel spindle and the workpiece clamping tile cutting blades  rigidity demanding.Width of grinding wheel grinding force, grinding power, first of all wheel drive motor power have a reasonable margin. In addition, the main components of the machine should have high accuracy and sufficient rigidity. If higher precision grinding wheel spindle, spindle elongation cantilever should be as short as possible

diamond truing tool used for attention

1 using the new dresser, before finishing the last feeding should exit. Many crisp diamond dressing tools, at the beginning of his contacts with the wheel, are easily damaged.
(2) in an inclined angle of 10 ~ 15 ° diamond dressing tool head mounted to point to the direction of rotation of the wheel.
3 securely installed or clamping dresser dressing tool, not the tool head hanging too long.
4 Where possible, try to use  carbide tipped saw blade coolant. Throughout the finishing time, with coolant pouring dressing tool and the wheel contact point.
5 In the dressing beginning from the highest point of repair from the grinding wheel, usually the middle wheel.
6 Note that except for a slight amount of repair. In addition to the maximum depth of repair, except for tinkering: 0.001 to 0.002 inches. Except for finishing: 0.0005 to 0.001 inches.
7 Press the relevant manuals choose the right lateral quickness. The slower moving laterally (in the allowable range), the lower surface roughness obtained wheel.
8 must be within the specified time interval for dressing the grinding wheel to prevent the wheel blunt, the grinding force increases.
9 at predetermined intervals, the toolholder the dressing tool rotating 1/8 turn, to ensure that the dressing tool is always sharp.
10 When the diamond dresser or tool head blunt or obvious change in peacetime, should be timely adjusted and replaced.
11 According to the diameter of  metal grinding wheel the wheel, the amount of a reasonable choice of diamond CARAT (pure diamond content), the larger wheel diameter, the larger the value of the selected CARAT diamond.
Incorrect:
1 diamond dressing tools in place to clamp head, be careful not to bump into the wheel surface.
2 can not be a single point diamond dressing tool head vertically aligned wheel center to be inclined generally 10 ~ 15 °.
3 heat dressing tools can not be "quenched" (refers to sudden cold). In the dry dressing must be kept trimmed twice the interval sufficient to heat the dressing tool cooling.
4 wheel surface can not be assumed to concrete cutting  have ideal flat. When trimming the beginning to find the highest point of the wheel position for trimming.
5, if possible, in addition to the amount of each wheel of the repair, the radius of the wheel can not be more than 0.001 inches. In addition to the amount of the repair is too large diamond dressing tool head can cause premature wear and often broken.

the stainless steel grinding wheel

he hardness of the stainless steel grinding wheel is generally within the range C ~ N, where J, K, L, M use of the wheel. Microcrystalline corundum grinding wheel face, the selection of appropriate hardness J. In addition, large diameter grinding wheel face bore or grinding, the grinding wheel and the workpiece contact surface, the wheel is easy step pads  to passivation, to be elected lower hardness wheel; grinding forming surface, should increase the hardness of the wheel , otherwise they will be faster wheel wear and damage-surface precision grinding wheel; grinding hollow and thin wall of the workpiece, the workpiece deformation, and  concrete blades therefore should adopt a softer wheel; discontinuous surface grinding, abrasive easy to fall off, you should use a hard wheel.Organization
Stainless steel toughness, strong adhesion, to avoid clogging the grinding wheel, grinding wheel organizations should  diamond cup wheels choose a more loose, generally 5-8 is appropriate. Back to eat large knife and a large contact area should be selected organization loose wheel, the surface roughness Ra values ​​that require low or form grinding should be used in a more compact organization of the wheel.the wheel before use, to floating tapping with a mallet, the sound should be crisp, metallic sound! If the sound is muffled, for the voiceless, usually in transit collision, absolutely not allowed!

Width of grinding wheel

Width of grinding wheel grinding force, grinding power, first of all wheel drive motor power have a reasonable margin. In addition, the main components of the machine should have high accuracy  diamond blade saws and sufficient rigidity. If higher precision grinding wheel spindle, spindle elongation cantilever should be as short as possible, a reasonable choice of spindle bearing structures, such as hydrostatic bearing stiffness and rotation to obtain better accuracy. Workpiece headstock spindle and tailstock sleeve overhang minimize, the choice of a larger size, shorter overhang top, and as far as possible so that the headstock, tailstock rigid consistency. Tailstock sleeve spring should have sufficient clamping force. Wheel rack rails  tile saw blade should also have sufficient rigidity.
 Width of grinding wheel grinding heat large, so should supply sufficient grinding fluid. Estimated according to the following empirical formula Q = bs / 2 (where Q - Flow L / min bs - Wheel width mm).
 Width of grinding wheel, grinding wheel airflow generated large grinding fluid nozzle and the wheel guard should be tuck point blades  set block air baffle, the shape of the nozzle should ensure grinding fluid spray to the entire width of the grinding wheel, and a smoke fog devices.
 Width of grinding wheel grinding with the best grinding force control device, so that both or full width of grinding wheel performance, and avoid overload grinding, in order to ensure safe operation.

Diamond wheel is grinding carbide

glass, ceramics, precious stones high brittle materials effects tools. In recent years, with high-speed grinding ultra-precision grinding technology developed rapidly, put a higher demand on the grinding wheel, ceramic resin bonded grinding wheel has been unable to meet production needs, because of its combination of metal bonded grinding wheel, high  strength, good formability, long life and other significant characteristics of wood drill bits  the production has been widely used. Metal bond diamond wheel manufacturers in different ways according to a major sintering, plating two types. In order to give full play to the role of super abrasive abroad from the 20th century, the early 90s with a high temperature brazing process to develop a new wheel, ie high temperature brazing monolayer superabrasive grinding wheels, this wheel is still in the current domestic research and development stage.
Ceramic diamond wheel vitrified diamond grinding wheel with diamond and vitrified common characteristics, and general 4 inch saw blades  corundum, silicon carbide grinding wheel compared to its grinding force, grinding temperature is relatively low, the wheel wear is relatively small; can be adapted to each species coolant effect; grinding wheel is good shape retention, high precision grind the workpiece; wheel has more pores, grinding and heat conducive chip, clogging, easy to burn the workpiece; wheel good self-sharpening, finishing a long time interval, trimming easier. Therefore, vitrified diamond grinding wheel used in some foreign countries is increasing.
Sintered diamond wheel
Sintered metal-bonded grinding wheels mostly bronze and other metals as a binder, with the manufacture of high-temperature sintering method, which combines high strength, good formability, high  ring saw blades temperature, thermal conductivity, good wear resistance, long life, can withstand greater loads.
Electroplated diamond grinding wheel:
① plating process is simple, less investment, ease of manufacture;
② without dressing, easy to use;
③ monolayer structure determines it can reach very high operating speed, the current foreign countries have been as high as 250 ~ 300m / s;
④ Although only a single layer of diamond, but there is still enough life;
⑤ For high accuracy, roller wheels, electroplated unique manufacturing method. Precisely because of these advantages, plating wheel speed, ultra-high speed grinding occupy undisputed dominance.

thick diamond tool sharpening

Thick diamond tool machining methods: mechanical grinding, hot metal plate polishing, ion beam, laser beam and the plasma etching.sintered diamond toolThe roll grinding with diamond thick destruction method 12 inch saw blade  for processing into an average particle size of 32 ~ 37μm diamond grains or the direct use of the legal system HPHT diamond grains, the grain powder stacked on WC-16wt% Co alloy, and then use Ta foil to isolate, in 5.5GPa, 1500 ℃ under the conditions of sintering for 60 minutes, made of diamond sintered body, using this sintered into tools with high wear resistance.monocrystalline diamond toolSingle-crystal diamond tool is usually fixed on  dry cut blades the diamond crystal knife head, knife head with screws or plates fixed on lathe arbor. Diamond in the knife head fixation methods are: mechanical reinforcement method (the diamond surface polished base and pressurized with pressure plate fixed to the knife head); powder metallurgy (the diamond on the alloy powder by adding pressure in the vacuum sintering, the diamond knife fixed at the head); bonding and soldering method (using an inorganic adhesive or  cbn wheels other adhesive fixing diamond). Because the diamond and the substrate thermal expansion coefficient differences between the diamond easily loose.

Hollow drill called core drill

Hollow drill shank common types: straight shank, universal shank, Nitto handle, handle overtone
Definition is no coring drill, according to the results of the cutting tool called names. People use as a cutting tool twist drill has been a hundred years of history, because the drill twist drill core part is entirely negative cutting angle, cutting resistance is large, so the twist drill cutting forces 50% -60% is due to drill The drill core cause. Coupled with the earlier factors, it can not do much twist drill, processing larger deeper hole drilled holes must start from the expansion step by step until the tile cutting blades  reamer size to meet the requirements so far.
The advent of the hollow drill bit cutting expanded the scope of use of a relatively small force can be processed macroporous deep, hollow drill can also do a very big size, just cutting ruler on the use of better or best Just now, not only reduces the processing costs, also considered impossible processing methods possible.
