本文先介绍铰刀中存在的问題和原因,然后提出改进措施:增大容屑槽,采用不等齿距,拉铰刀、复合铰刀、发展刅倾角、螺旋角、大螺旋角铰刀,单办铰刀,硬质合金,金刚石和立方氮化硼铰刀。最后要求提高铰刀的制造精度,保证铰刀质量和发展铰刀的新品种。
This paper first introduces the problems and reasons existing in the reamer, and then proposes the improvement measures: to increase the chip flute, the use of unequal pitch, pull reamer, composite reamer, the development of inclination, helix angle, large helix angle reamer, Single reamer, carbide, diamond and cubic boron nitride reamer. Finally, it is required to improve the manufacturing precision of reamers, to ensure the quality of reamers and to develop new varieties of reamers.
