加工螺旋沟槽应设计专用成型铣刀。根据刀具的槽型尺寸、齿数、螺旋角等参数,通过计算给定成型铣刀的型面,用来制造专用铣刀。但实际生产中对于小批量甚至单件生产的各种专用螺旋铣刀的沟槽铣削,不可能也没有必要制造各种各样的成型铣刀库存备用。多年来我们一直使用单角铣刀铣螺旋沟槽。实践证明采用单角铣刀代替成型铣刀加工螺旋沟槽是适用的。但是我们在生产中使用的图纸,大部分给出的槽型角不正确或没有给出槽型角。工人在加工时选择铣槽用 Processing spiral groove should be designed for molding cutter. According to the tool groove size, number of teeth, helix angle and other parameters, by calculating the shape of the milling cutter given for the manufacture of special milling cutter. However, the actual production of small quantities or even a single production of various special groove milling cutter, it is impossible and needless to create a variety of milling cutter inventory. For many years we have been using single-angle milling cutter spiral groove. Practice has proved that the use of single-angle milling cutter cutter instead of spiral groove is suitable. But the drawings we used in production, most of the given groove angle is incorrect or does not give groove angle. Workers in the processing of choice milling slot
