The character of stainless steel and cutting machine the note of stainless steel material

5% ) so that be in apparently form conglutinate move and reborn oxidation chromic diaphragm, can achieve stainless steel quality. Most stainless steel is based on Fe-Cr-C and Fe-Cr-Ni-C body, but other alloying element is very important also. Can use a lot of kinds of alloy. Forming the main stage of small structure, can differentiate stainless steel for 5 main categories: Austenite stainless steel, ferrite stainless steel, double photograph stainless steel, martensite stainless steel and PH (precipitation sclerosis) stainless steel. austenite stainless steel and 42CrMo4 (use the alloy steel that makes cutting index referenced material understands thoroughly stainless steel to expect normally namely) undertake comparative, we can discover a few interesting differences: Stainless steel was shown than steel taller adhesiveness (and extend a gender) incline to. This means the data that is used at cutting stainless steel to must have taller tenacity, and their film must be " prevent conglutinate " model. The microcosmic chamfer of cutting blade very important, the Gao Yan malleability that the reason depends on it can compensating stainless steel ensures cut bits outstandingly to form ability. With common steel photograph comparing, should raise cutting rate in order to compensate tall adhesiveness incline to, still answer advertent all the more small collapse (the tumor accumulating bits that manages by point is brought about) , groove wears away and film flakes. Stainless steel still showed trend of taller sclerosis of meet an emergency, because this plants natural reason,data can raise to groove wears away and cause cutting blade small collapse. The correct and microcosmic chamfer of cutting blade can undertake compensating to this, because be in cutting process, sharp cutting blade can weaken sclerosis of meet an emergency. Cutting deepness needs successive change, so that should harden in cutting,dispersive groove wears away overmuch risk, and feed should as far as possible tall. Stainless steel has inferior thermal conductivity, this means a meeting to pass the quantity of heat with the less eduction that cut bits. More quantity of heat can deliver cutting blade to go up to make its heated, the high temperature hardness of cutting material is very accordingly important. Discretion answers when choosing cutting speed and feed, have capacity of the largest absorption of heat with limitation gives out heat and making cut bits. Plasticity is out of shape is consequence of model of tatty of stainless steel cutting tool. The hardness of stainless steel and steel quite, cutting force is in same standard, because this does not need to adopt special precautionary measures in order to compensate cutting force, with steel application is compared, also do not need to restrict cutting deepness and feed. Stainless steel still showed taller wearability, cause crescent moon to wear away quickly depression. The taller wearability of film of have the aid of, cutting tool can achieve higher utilization rate (the metal moves except rate / cutting tool life) . Apparent, cannot resemble pair of common steel the machinability that defines stainless steel in that way. Should use specific cutting tool to choose a process to process stainless steel, choose corresponding cutting operating mode. CNC Milling
