一般加工方孔和曲线形工件往往用插削。插削生产率一般比铣削低,但是在某些情况下,如方孔要倾角等,还必须用插削的方法。由于插刀工作条件差,所以一般插削的进给量较小,生产率的提高也就受到一定的限制。有些工厂往往在这道工序上形成薄弱环节。由于插削过程是冲击性的运动,在加工中振动大,又是断续的。一般插刀在切削时,首先是刀尖接触工件(或全部刀刃同时接触工件)由于刀具强度低、冲击力大、切削热集中在刀尖上,所以经常产生下列现象:1)由于刀具强度低、冲击力大会把刀尖碰坏;2)由于切削热全部
General processing square hole and curved workpiece is often inserted cut. Insert productivity generally lower than the milling, but in some cases, such as the square hole to tilt, you must also use the cutting method. Due to the poor working condition of the cutting insert, the feeding amount of the cutting insert is generally small, and the improvement of the productivity is also limited. Some factories often form a weak link in this process. As the insertion process is the impact of the movement, vibration in the processing, but also intermittent. General cutting tool in cutting, the first is the tip contact with the workpiece (or all the blades at the same time contact with the workpiece) due to low tool strength, impact force, cutting heat concentrated in the tip, it often produces the following phenomena: 1) , Impact Conference damage to the tip; 2) Due to cutting heat all
