不锈钢加工对刀具的要求及加工过程中刀具参数的选择。机械零件加工针对不锈钢时,刀具切削部分的几何形状,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。增大刀具的前角可减小切屑切离和清出过程中所遇到的阻力。对后角选择要求不十分严格,但不宜过小,后角过小容易和工件表面产生严重摩擦,使加工表面粗糙度
Stainless steel processing requirements of the tool and the choice of tool parameters in the process of processing. Mechanical parts processing For stainless steel, cutting tool geometry, generally should be from the front angle, the angle of choice to consider. In the choice of anterior horn, to consider the volume groove, with or without chamfering and inclination angle of the positive and negative angles and other factors. No matter what kind of tool, when processing stainless steel must use a larger rake angle. Increasing the rake angle of the tool reduces the resistance encountered during chip removal and removal. The choice of the rear angle is not very strict, but not too small, too small after the corner and the workpiece surface serious friction, the processing surface roughness
