为减少操作辅助时叫,提高数控机床的工作效率,目前较普遍地采用了机外刀具预调措施。对于数控车床来说,就是加工前在刀具预调仪(亦称对刀仪)上预先调定刀具在机床X向(横向)和Z向(纵向)的长度尺寸,以便控制刀尖在机床座标系中的起始位置。为了达到这个目的,通常使用可调式刀扪(图1)。可转位刀片或小刀头以机械零件夹紧固定的方式安装在刀杆上,刀杆的尾部和侧部分别设有一个和两个可调螺钉。改变这三个螺钉拧入的深度,就可以控制图1中的刀具预调尺寸Lx和LZ。这两个尺寸一般由编程员选定,并在
In order to reduce the number of auxiliary operations to improve the work efficiency of CNC machine tools, the more commonly used outside the tool presetting measures. For CNC lathes, the length of the tool in the X direction (horizontal direction) and Z direction (longitudinal direction) of the tool is pre-set on the tool presetter (also known as the tool setting tool) before machining so as to control the tool tip on the machine tool base The starting position in the label. To achieve this goal, usually using adjustable knife palpable (Figure 1). The indexable blade or knife head is mounted on the arbor with the clamping of the mechanical parts in a fixed manner. One or two adjustable screws are provided at the tail and side of the arbor respectively. By changing the depth at which these three screws are screwed in, you can control the tool preset dimensions Lx and Lz in Figure 1. These two sizes are generally chosen by the programmer and are
