加大刀具切削刃工作部份的作用长度,是精车和半精车加工中提高生产率的最有效方法之一。应用切削刃作用部份大的车刀,如:小偏角的车刀,宽头车刀等,在高速加工时,使生产率显著的提高。但用上述车刀来切削时,会产生一种宽而薄的切屑,这在形成震动的观点来说,是一个不利的倏件。 Increasing the working length of the cutting edge of the tool is one of the most effective ways to improve productivity in finishing and semi-finishing machining. Application of cutting edge part of the role of large lathe, such as: small declination of the lathe, wide lathe, etc., in high-speed processing, so that productivity was significantly improved. However, when cutting with the turning tool described above, a wide and thin chip is produced, which is an unfavorable artifact in terms of vibration.
