由于现代机床的功率不断提高,并能传递更大的扭矩;同时高性能的材料制成的刀具,如今已允许采用高速、大进给进行切削,所以ISO标准锥柄的刚性往往已不能满足要求了。特别是当刀具工作部分直径大于连接部分直径,或者刀具悬伸量大时,这个问题更为突出。通常,刀具的悬伸长度超过其直径4倍时,其刚性即不能令人满意。本文所述的ABS系统,由于连接部分支承面显著增大,定位精度提高,在刚性、可传递的功率、自动换刀精度和时间方面,均有很大的改进。
Due to the increasing power of modern machine tools and the ability to deliver greater torque, tools made of high-performance materials have now allowed high-speed, large-feed cutting to be performed, so the rigidity of ISO-standard taper shanks often fails to meet the requirements It’s This problem is especially noticeable when the diameter of the working part of the tool is larger than the diameter of the connecting part or when the overhang of the tool is large. In general, when the overhang length of a tool exceeds 4 times its diameter, its rigidity is unsatisfactory. The ABS system described herein, due to the significant increase in the bearing area of the connection section, improves the positioning accuracy and greatly improves rigidity, transferable power, automatic tool change accuracy and timing.
