近年来我厂根据国外有关技术资料,并结合生产实际,研制和改进了单刃铰刀。实践证明,单刃铰刀在孔加工刀具中确是一种有前途的刀具,可用于普通孔、深孔、更适用于盲孔加工;半精加工、精加工;零件内孔表面光洁度稳定在▽6,在其他条件选用适当可达▽8,精度稳定在3级,可达2级;工效普遍提高2～4倍,现我厂巳稳定用于生产。特介绍如下: 一、特点1、齿少、容屑空间大、刀齿强度好,便于容屑、排屑。
In recent years, our factory based on foreign technical information, combined with the actual production, development and improvement of the single-edged reamer. Practice has proved that single-edged reamer in the hole machining tool is indeed a promising tool, can be used for ordinary holes, deep holes, more suitable for blind hole machining; semi-finishing, finishing; parts of the hole surface finish stable ▽ 6, in other conditions, the appropriate choice of up to ▽ 8, the accuracy of stability at 3, up to 2; work efficiency generally increased 2 to 4 times, I plant has been stable for the production. Special introduction is as follows: First, the characteristics of 1, less teeth, the chip space, tooth strength, easy to chip, chip evacuation.
