Arbor material requirements when processing stainless steel, due to the cutting force is large, so the arbor must have sufficient strength and rigidity to avoid chatter during cutting and deformation. This requires the selection of an appropriate cross-sectional area larger arbor, while also higher strength materials used to manufacture Arbor, such as using a No. 45 or No. 50 steel quenched and tempered steel processing.      Portion of the material of the cutting tool when machining stainless requirement, part of the cutting tool requires the material with high wear resistance, and can maintain its cutting performance at higher temperatures. The most commonly used materials are: high-speed steel and carbide. Since the high-speed steel cutting can only maintain its 600 ° C in less, so not for high-speed cutting, and only applies to the processing of stainless steel at low speed. Since the ratio of high-speed steel carbide has better heat resistance and wear resistance, thus cutting tools with carbide material more suitable for stainless steel machining. Tungsten carbide-cobalt alloy points (YG) and tungsten-cobalt titanium (YT) two categories. Tungsten-cobalt alloy has good toughness, the tool can be made using a large rake angle with a relatively sharp edge sharpening, the cutting process chip deformation, cutting light, the chip is not easy to stick the knife, so in general under the circumstances, with the tungsten-cobalt alloy stainless steel processing more appropriate. Especially in larger vibration roughing and interrupted machining case should adopt tungsten-cobalt alloy blades, it is not as brittle as tungsten-cobalt alloy, easy sharpening, easy to chipping. Red hardness of tungsten-cobalt titanium better conditions than at high temperature wear-resistant tungsten-cobalt alloy, but it's brittle, impatient shock, vibration, generally for stainless steel finishing with knives.
