在机床外进行刀具的预调整(以下简称机外对刀)是提高生产效率和减少对刀废品的有效手段。这里介绍一种简单、可靠、经济的定位测量机外对刀法。这种方法要求制造特殊的刀杆,以便按照零件加工部位,保证刀具要求的尺寸,在刀杆的侧面带有可调节的定位螺钉。机外对刀装置简图见图1。 Pre-adjustment of the tool outside the machine tool (hereinafter referred to as the external knife) is to improve production efficiency and reduce the tool on the effective means of scrap. Here is a simple, reliable, economical positioning measuring machine outside the knife method. This method requires the manufacture of a special arbor in order to guarantee the dimensions required by the tool in accordance with the parts to be machined, with adjustable set screws on the sides of the arbor. Outside the knife device diagram shown in Figure 1.
