Kim saw blade grinding must be noted at the time

Factor in the use of gold saw blade grinding to note about the : 1 , coolant grinding teeth grinding fluid that is good or bad decision . When a large amount of tungsten partridge grinding , diamond grinding wheel powder, not timely flushing and cleaning of the grinding wheel tool surface pores, resulting in surface grinding tool can not grind finish, there diamond blades  is not enough cooling will burn alloys. 2, the grinding mechanism for grinding teeth affected. Alloy saw blade grinding machine structure and assembly that is good or bad , about the current market two types of models: one is floating in Germany Seoul ink types. The type with vertical grinding off , all the advantages of using hydraulic stepless movement , all the feed system using V -rail and ball screw work , grinding or arm using the jog feed retraction rewind, adjust the fuel tank clip heart, flexible and reliable support piece , pulling teeth accurate positioning, strong self-centering blade positioning heart , any angle adjustment , cooling rinse reasonable man-machine interface , high precision grinding off , pure grinder rational design ; II , which is currently horizontal such as Taiwan and Japan models, the presence of mechanical transmission gears and mechanical clearance dovetail slide accuracy, low steady performance clips , adjust the difficulty heart support piece , pulling teeth institution or poor reliability, after the plane left and right sides and an angle not mind grinding cut , resulting in large deviation angle difficult to control, mechanical wear disaster ensure accuracy. 3 , welding factor. Welding alloys deviation big impact precision grinding , grinding pressure while causing great pressure on the small side , rear corner also produce the above factors, the welding angle difference , inevitable human factors , all of the grinding wheel, and other factors produce an unavoidable impact . 4 , wheel width on the quality and size . Optional wheel run- gold films , pay attention to wheel size , granularity is too coarse grinding wheel produced traces wheel grinding selected fine grain size is less easy to plug , easy to burn knife. Wheel diameter and thickness is based alloy wheel width or different tooth width and the length of each side alloy case may be , not a corner after corner or front wheel can be any size as different tooth grinding , must be targeted to choose a  diamond cut off wheel suitable Specifications wheel. 5 , grinding feed rate. Alloy blade grinding entirely good or bad decision grinding feed rate , generally alloy saw blade feed rate from 0.5 to 6 mm / s can not exceed this value that should be within 20 teeth per minute per minute exceeding 20 tooth feed rate is too large , it will have a serious knife tumor or burn alloy wheel produces concave surface affect the accuracy of the waste grinding wheel . 6 , grinding feed rate , the choice of wheel size on the amount of feed has very important significance. General Wheel suggested the use of 180 # 240 # 240 # to most, the choice not to choose 280 # 280 # to 320 # , or to adjust the feed rate. 7 , grinding heart. All grinding the blade and the substrate for the heart, rather than with the blade of the heart, the heart does not get out surface grinding , horn , front  Dressing plates corner with a processing center can not be sharpened a blade , blade grinding three processes Heart can not be ignored . Grinding side angle still careful observation alloy thickness , thickness change with different grinding heart , no matter how the alloy thickness , surface grinding wheel center line should be kept with the welding position in a straight line , otherwise the impact of cutting angle difference . 8 , pulling teeth institutions can not be ignored . Regardless of how the structure of any grinding , pulling teeth to coordinate accuracy Brothers Design quality , acupressure pulling teeth tooth surface in a reasonable position at the time of transfer machines, and not with the move is extremely critical , when back teeth , pulling teeth jaws should flexible and reliable.

Determination of diamond grinding wheel diamond content Tablets

How to determine the content of the diamond film diamond wheel, we must first understand what it is per cubic centimeter (cm3) containing the number of carats (ct) diamonds to be calculated. Details as follows:
  1. 1.1ct/cm3 = 25%, 2.2ct/cm3 = 50%, 3.3ct/cm3 = 75%, 4.4ct/cm3 = 100%, 5.5ct/cm3 = 125%.
  2. Ct diamond carat refers to  polishing pads for granite the weight not volume, 1ct = 0.2g.
  3 This method is the total content of the resin bond diamond wheel method. Ceramic metal-binding method and binding method, combined with the exception electroforming method.
  4 low levels were used to reduce abrasive grinding Omo impedance, high levels were used for forming an acute  grinding wheels angle grinding in order. Circular or other special shapes.
5 to diamond resin grinding wheel specification illustrate SDC150P100B that SDC diamond abrasives - 150 grit thickness - P end-stage combined hardness - content 100% (per cubic centimeter containing 4.4 kt diamond abrasive) -.

Field of use of diamond tools

Diamond is the hardest, so in stone, building materials processing, diamond cutting tool is a good tool. Diamond tools such as diamond saw blades and wear-resistant materials in non-ferrous metal processing applications, has excellent adaptability. Use the following detailed description of the field of diamond tools.
When using diamond tools, users  concrete diamond blades have two options: one is polycrystalline diamond (PCD), the other is a relatively new chemical vapor deposition (CVD) diamond.
Early use of proven performance
Polycrystalline diamond has a natural diamond hardness, strength and abrasion resistance, but does not damage the sensitivity of natural diamond. It is at high temperature, the polymerization of the synthetic diamond particles. In the process, while the polycrystalline particles is integrally formed is bonded to a cemented carbide substrate on to improve the mechanical strength and impact resistance.
PCD is applicable to high-speed cutting of aluminum, is particularly suitable is required to achieve good surface roughness of the main case, it is in the processing of high wear resistance, and exhibits excellent performance. Typically, PCD recommended for cutting high silicon aluminum alloy, but also for brass, copper, bronze, and carbide processing. Processes used include turning, boring, profiling, grooving, milling and hole processing.
As the chemical reaction between the diamond and iron, in general, does not apply to the processing of ferrous metals PCD material. However, it can deal with the processing of bi-metal material, comprising a combination of aluminum and iron included. For example: a car parts suppliers in the processing of aluminum and cast iron cylinder bi-metal body with a diameter of 305mm wafer type face milling cutter, corner radius 2.36mm, with repair knife, cutting 304.8m/min, feed 0.10 mm / tooth, depth of cut 5mm, processing up to the 5000 cylinder block, indexable inserts only need one.
By the mass production industry, primarily grinding cup wheels  in the automotive industry increasing push aluminum processing speeds. Meanwhile, car manufacturers in order to reduce weight and reduce costs, is on the use of metal matrix composites evaluated, and such materials must be processed by PCD. He said: "Such material can not be processed using carbide tools."
Polycrystalline product manager, said that although the PCD development achievements have been giving a very deep impression,
PCD tools in terms of scope and production efficiency, have brought many benefits to the process. Although the diamond is the hardest available materials, the material characteristics and toughness problems still further. One factor to improve the toughness of PCD is plus cobalt is not directed it into a random arrangement between the diamond grains. Further, the cemented carbide substrate of the diamond abrasive layer can also act as a mechanical support, thereby increasing the impact resistance, and ease of manufacture of brazed tool.
Another benefit of the PCD, the existing series of various grades have been able to meet any need to use non-ferrous metal processing. In general, the fine particles are less wear diamond for materials processing require very high surface roughness of the occasion; diamond  sand paper particles in general as generic brands machining; coarse diamond for roughing the special anti-wear material, but the surface roughness of less demanding place.
Bright future
At present, many production sites do not take full advantage of the diamond. The reason is that a lot of speed and torque tools are not sufficient to ensure the efficient functioning of the tool.
In addition to mechanical problems, there is a difficult problem is to convince people to produce the factory, do not just stare at diamond (PCD or CVD diamond) set the initial price, but to see it brings cost savings and improved performance benefits. You can make a diamond tool than conventional operation (depending on machine performance may be) at a higher speed, thereby enhancing the volume of output. Meanwhile, fewer tool changes. Assume diamond carbide than 50 times to 100 times higher life, you do not often stop it.

etermine the characteristics of the grinding wheel grinding process system can make even micro cutting

 Grinder with grinding wheel as the cutting tool on the workpiece machining methods. This method features:
 (1) Since the abrasive grinding wheel itself wet polishing pad  has a high hardness and heat resistance, high hardness can be processed so grinding materials such as hardened steel, carbide, etc..
 (2) determine the characteristics of the grinding wheel grinding process system can make even micro cutting, the general ap = 0.001 ~ 0.005mm; grinding speed is high, generally up to v = 30 ~ 50m / s; grinder stiffness; adopts hydraulic transmission Therefore grinding energy and affordable access to high precision (it6 ~ it5) small surface roughness (ra = 0.8 ~ 0.2μm). Grinding parts finishing the main methods.(3) As intense friction, leaving the grinding zone temperature is high. This can cause deformation of the workpiece to produce stress, and even cause surface burns. Therefore, a lot of grinding coolant must be injected to reduce the grinding temperature. Coolant may also function as a lubricant chip (4) grinding large radial force. This will cause the machine - grinding wheel - workpiece system flexibility retreat, so that the actual depth of cut less than the nominal depth of cut. Therefore, the grinding will be completed when the light is not to be  diamomd core drill bits infeed grinding to remove the error.(5) After blunt abrasive, grinding force also increased, resulting in grain crushing or off, exposing sharp edges again, this feature is called "self-sharpening." Self-sharpening grinding a certain period of time to make normal, but after more than a certain work should be carried out manually trimmed to avoid grinding force increases caused by vibration, noise and damage the workpiece surface quality.Wheel speed working conditions, in order to ensure safety, should be checked before installation, there should be no cracks and other defects; wheel work to make a smooth, dynamic balance test should be carried out before use.Grinding work after a certain time, its surface will be void debris clogging the abrasive concrete saw blades  acute angle will blunt the original geometry is distorted. Therefore, to restore the cutting ability of the dressing to be correct geometry. Wheel dresser diamond pen required.Structure and surface grinder grinding motionMany different types of grinding machines, mainly surface grinder, cylindrical grinder, internal grinder, universal cylindrical grinding machine (also can grind the hole), gear grinding, thread grinding machine, rail grinding, centerless grinding (grinding cylindrical) tool grinder (grinding tool ), etc.

Practical of diamond tools

Diamond tool is mainly used for a variety of non-ferrous metals such as aluminum turning , copper, magnesium and its alloys , tungsten carbide and wear strong fiber reinforced plastic materials, metal matrix composites, wood and other non-metallic materials . When cutting speed, feed  concrete diamond blades rate and depth of cut depends on processing conditions and the hardness of the workpiece material . Synthetic polycrystalline diamond compact (PDC) properties and applications close PCD tool , mainly used in non-ferrous metals , tungsten carbide , ceramics, non-metallic materials ( plastic , hard rubber, carbon rod , wood, cement products, etc. ) , composite materials such as cutting, gradual replacement carbide cutting tools . Because edge polishing pads  the diamond particles bonded to ask some residual metal and graphite , in which the bonding metal or showed coalescence vein -like distribution state will reduce tool wear and life.
In addition there is a metal residue solvent , solvent metal in direct contact with the diamond surface . Lower (PDC) oxidation resistance and tool heat resistance , the cutting tool is not stable enough. Thick Diamond Tool preparation process is complex, because of the low melting point metals and their alloys and diamond has a high interfacial energy between . Diamond is difficult to be generally low melting point  PCD grinding wheel solder alloy infiltration. Weldability poor , difficult to produce complex geometry tool , it can not be applied TDF welding tool in high-speed milling . Diamond- coated tools can be applied to high-speed machining , because in addition to diamond coated tools have excellent mechanical properties, diamond coating process can be prepared any complex shape cutters for high speed machining aerospace materials such as aluminum alloy and refractory processing of non- metallic material such as graphite electrodes.

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 .

Ceramic coated abrasive grinding wheel of introduction

The abrasive wheel for ceramic coating and metal bonded grinding wheel for which the same advantages , and now small will take everyone to know, I hope we can bring convenience .
Ceramic grinding wheel for the  bandsaw blades superabrasive grains coating shows with metal bonded grinding wheels for the same benefits: helps control between vitrified abrasive and potentially harmful chemical reaction. Titanium is used in such typical material coating superabrasive grains , grains of titanium coating helps to reduce binding agent in adverse chemical reactions may occur . The metal bonded grinding wheel , the coating is to protect the diamond abrasive grains from the bonding agent system; while in vitrified grinding wheels , the coating is to protect the system from the binding agent of CBN grains .
Similarly, the abrasive coating also enhances the gripping force . In the glass ceramic material used in grinding is not ' wet ' , or not with the surface of the uncoated abrasive grains combined well , so the abrasive coating of titanium carbide coated abrasive grains  hole saw blades can improve the wettability and increase gripping force . After grinding wheel diamond pen can be used to stop trench repair , you can also use the wheel cutting blade repairs, but to use the wheel when the usual mundane as possible to add more value appearing grooves.
Hand sharpening wheel using alumina and silicon carbide are greatly wheel, aluminum alloy wheel for carbon steel class tools, such as high speed steel cutting tools and object class steel drill bit . Silicon carbide grinding wheel for carbide tools .

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.

Exchangeable-head tools new progress

It is acknowledged that drilling is the most widely used machining process, both in machining centers, CNC lathes, or in special drilling machine, drilling can be carried out. Processing cost per hole, drilled hole quality and integrity are selected drill and process the key factors to consider when. Often you can put some relevant processing operations such as reaming, chamfer, expanding drilling and boring integrated in a tool, in the drilling easily accomplish together.
Replaceable drill tip drill in the late 1990s came, when the drill bit carbide drill tip wear, can easily be replaced without having to drill cutter body from the holder and / or remove the spindle . Each of the steel blade suitable for the given size range crown of different diameters, the user no need to drill a hole the diameter of each purchase of a specific drill size, which can save costs. Typically, drill cutter body can be covered with pore size of about 1mm, many vendors drill tool tip diameter diamond hole saw  increments of 0.10mm.
In the drill bit replacement carbide steel cutter body concept to guide the drill tip interchangeable modular reaming head cutters and system development, and the same success, allowing users to benefit greatly.
Replaceable drill tip drills advantages in the following areas:
(A) save a lot of machining operations and tool management costs;
(2) reduce the use of carbide cutter body material;
(3) longer tool life and hole machining predictability;
(4) reduces drill inventory;
(5) eliminates the need for regrinding the drill bit, back up the tool and the desired fluidity;
(6) loaded knife significantly shorten the time, because it is in the holder on the machine and replace the drill tip, without presetting, compensation and the knife.
In order to correctly select the drill type, you will need to correctly answer questions about drilling dimensions, tolerances and surface finish requirements, as well as machining tasks or workshop  brick saw blades economy and other issues. For the processing of diameter less than 12.7mm, taking into account the machining precision and performance, solid carbide drill bit is still the recommended solution; diameter greater than 25mm for processing (especially roughing), recommend the use of indexable insert drills. The power tool on the processing of more than 25mm or even 51mm diameter holes, the use of indexable drills particularly effective.
In the range of 12.7-25.4mm diameter between drilling, you can change the drill tip drills have become a common choice because it can provide both precision drill hole on capacity and cost-effective, measurable overall competitive advantage. Carbide drill tip with the concrete cutting blade  workpiece material and processing requirements for optimizing drill tip shape design features, and usually without regrinding, so replace each drill tip is new, its processing performance and all the other new drill tip identical and re-grinding of solid carbide drills can not do this.

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.
