锥、柱形等螺旋角切削刃组合刀具是一种较为理想的优质高效刀具。在铣、铰刀具上均有应用。特点是刀具每一个部位的切削刃的螺旋角相等,故其前角保持不变,对稳定切削性能起重要作用。但是,由于等螺旋角的加工比较困难,所以其发展缓慢。在航空工业中,适宜采用锥、柱形刀具加工的零件较多,如能方便地加工制造等螺旋角切削刃刀具,将有一定的意义。我厂过去采用等导程的锥形螺旋铰刀,由于前角随直径而变化,使零件加工质量不稳定,成为生产中的关键。采用等螺旋角切削刃锥形刀具后,改善了
Cone, cylindrical helical angle cutting edge combination of cutting tools is an ideal tool for high quality and efficiency. In milling, reamer tools are applied. It is characterized by the same helix angle of the cutting edge in every part of the cutter, so its rake angle remains unchanged, which plays an important role in stable cutting performance. However, its development has been slow due to the difficult processing of equal helix angles. In the aviation industry, it is appropriate to adopt conical and cylindrical tools to process more parts, and it is of significance to be able to conveniently manufacture and manufacture helical-angle cutting edge tools. I used to wait for the factory before the cone-shaped spiral reamer, as the angle with the diameter changes, the quality of parts processing instability, a key to production. After using a helix angle cutting edge cone cutter, improved
