不锈钢加工时对刀具几何参数的要求,一般应从前角、后角方面的选择来考虑。在选择前角时,要考虑卷屑槽型、有无倒棱和刃倾角的正负角度大小等因素。不论何种刀具,加工不锈钢时都必须采用较大的前角。对后角选择不宜过小,但也不宜过大,后角过大,使刀具的楔角减小,降低了切削刃的强度,加速了刀具的磨损。通常,后角应比加工普通碳钢时适当大些。 The requirement of the geometrical parameters of the tool when processing stainless steel, the choice of the former Angle and the rear Angle should be considered. When choosing the front Angle, it is important to consider the Angle of the roll, the Angle of the Angle of the chamfer, the Angle of the Angle of the blade, etc. No matter what the tool, processing stainless steel must use the big front Angle. The choice of the rear Angle should not be too small, but not too big, the rear Angle is too big, the wedge Angle of the cutter is reduced, the strength of cutting edge is reduced, the wear of the cutter is accelerated. Usually, the rear Angle should be larger than the normal carbon steel. 不锈钢零件加工时对刀杆材料的要求,刀杆必须具备足够的强度和刚性,以免在切削过程中发生颤振和变形。这就要求选用适当大的刀杆截面积,同时还应采用强度较高的材料来制造刀杆,如采用调质处理的45号钢或50号钢。 When the stainless steel parts are processed, the tool must be strong and rigid so as not to be flutter and deformed during the cutting process. This is required to select the appropriate size of the blade, and also use the high strength of the material to make the tool, such as the 45 steel or 50 steel that are treated with the adjustment. 不锈钢零件加工时对刀具切削部分材料的要求加工不锈钢时,要求刀具切削部分的材料具有较高的耐磨性,并能在较高的温度下保持其切削性能。目前常用的材料有:高速钢和硬质合金。 To tool cutting part when stainless steel parts processing for processing of stainless steel material for tool cutting part of the material has high wear resistance, and can at high temperature to keep its cutting performance. Currently used materials are: high speed steel and hard alloy. 由于高速钢只能在600°C以下保持其切削性能,因此不宜用于高速切削,而只适用于在低速情况下加工不锈钢。由于硬质合金比高速钢具有更好的耐热性和耐磨性,因此用硬质合金材料制成的刀具更适合不锈钢的切削加工。 Due to the high speed steel can only be below 600 ° C to keep its cutting performance and therefore should not be used for high speed cutting, and is only applicable to stainless steel under the condition of low speed processing. Because hard alloy has better heat resistance and abrasion resistance than high speed steel, the tool made of hard alloy material is more suitable for stainless steel machining
