Processing of stainless steel, because of the cutting force is bigger, so the tool holder must have sufficient strength and rigidity, so as not to attack in the process of cutting chatter and deformation This request to choose appropriate tool rod sectional area, at the same time should also be made of high strength materials to make tool rod, such as using the tempering treatment or 50 # steel 45 # steel

Processing of stainless steel, tool cutting requests local material with high wear resistance, and can at higher temperatures insists that its cutting performance Now commonly used materials are: high speed steel and carbide Due to the high speed steel only under 600 C insists that its cutting performance and therefore should not be used for high speed cutting, and is only applicable to processing of stainless steel under low speed condition Because the cemented carbide than high speed steel has better heat resistance and abrasion resistance, thus made of hard alloy material cutting tool is more suitable stainless steel machining

Processing stainless steel cutlery, knives cutting local geometric shape, ordinary should horn after former options to consider When choosing rake Angle, to consider volume trough type Presence of chamfering and blade Angle of positive and negative elements such as point size No matter what kind of cutting tools, processing of stainless steel are necessary using large increase of the anterior horn of tool rake Angle can reduce chip encountered in the process of cutting off and clear the resistance To choose a Angle after the request is not very strict, but shoulds not be too small, the Angle is too small to have serious friction and artifacts appearance, worsen the processing surface roughness, speed up the tool wear And because the intense friction, strengthened the effect of strain hardening stainless steel appearance; The corners of the cutter should not be too large, and the rear Angle will be too large to reduce the wedge Angle of the cutter, reducing the strength of the cutting edge and accelerating the wear of the cutter. The rear Angle should be more appropriate than that of ordinary carbon steel

Progress tool cutting locally to reduce the appearance of brightness chip constitute the crimp resistance, the progress of cutting tool durability compared with common carbon steel processing, processing stainless steel should be appropriate to reduce cutting dosage to slow the tool wear; At the same time, the proper cooling smooth solution is also selected to reduce the cutting heat and cutting force in the cutting process and prolong the life of the cutter

Stainless steel cutting tools are not really not rust, just because of chrome steel containing 13% ~ 18% and other alloy elements (such as vanadium molybdenum cobalt) will compare tool steel rust resistance stronger, if still will rust in the case of improper use, such as acid rain water sweat will also accelerate the stainless steel surface oxidation
