diamond tool on the part of the surface roughness of

Diamond tool in the machining of stainless steel, the cutting force of the diamond, the shank must have sufficient strength and rigidity, in order to avoid chatter occurs during the  tile cutting blades cutting and deformation processing of stainless steel, diamond tool cutting portion geometry, generally should rake angle, clearance angle, the options to consider. In the choice of the anterior horn, consider the volume crumbs groove, without chamfering and edge inclination angle of the sign size and other factors. Regardless of the tool, machining stainless steel must use a larger rake angle. Increasing the rake angle of the tool can be reduced, and cleared from the chip during the cutting resistance encountered. Right rear corner selection requirements are not very strict, but not too small, after the angle is too small and the surface is easy to cause serious friction, so that surface roughness deterioration accelerated tool wear. And due to strong friction and enhancing the effect of hardening the surface of stainless steel; tool clearance angle is not too large, after the angle is too large, the tool of the wedge angle decreases, reducing the strength of the cutting edge, accelerated wear of the tool. Typically, the posterior horn should be higher than ordinary carbon steel processed appropriately larger.
Diamond tool cutting part of the tool surface roughness requirements
Improve the surface finish of the cutting part of the tool can reduce the formation of diamond chips curled resistance, improved durability of the tool. Compared with the processing of ordinary carbon steel, stainless steel processing should be appropriately reduced to slow the cutting tool wear; also select the proper coolant in order to reduce the cutting process of cutting heat 14 inch saw blade  and cutting force, extend tool life.
Material requirements for Arbor
Stainless steels, the cutting force of the diamond, the shank must have sufficient strength and rigidity in the cutting process in order to avoid chatter and distortion occurs. This requires the choice of appropriate cross-sectional area larger arbor, while also using higher strength materials to create Arbor, such as the use of quenched and tempered steel 45 or 50 gauge steel.
Cutting portion of the tool material requirements
Stainless steels, the required portion of the cutting tool material has a high wear resistance at high temperatures and can maintain its cutting performance. The most commonly used materials are: high-speed steel and carbide. As high-speed steel only 600 ° C the following to maintain its cutting performance, it is not appropriate for high-speed cutting, but only to the case of stainless steels at low speeds. Since carbide than ring saw blades  high speed steel with a better heat resistance and wear resistance, hence the cemented carbide cutting tool made of a material more suitable for cutting of stainless steel.
Carbide of tungsten-cobalt alloy (YG) and tungsten-cobalt alloy (YT) two categories. Especially in larger vibration roughing and interrupted machining circumstances should adopt tungsten-cobalt alloy blades, it is not as brittle as tungsten-cobalt alloy, diamond grinding is not easy, easy chipping. Tungsten-cobalt alloy red hardness is better at high temperatures than tungsten-cobalt alloy wear, but it's brittle, intolerant shock, vibration, generally made of stainless steel finishing with a diamond cutter.
