数控对刀仪是数控加工中心、数控车床不可缺少的辅助工具。它的基本工作原理如图1，通过刀具底下的高强聚光灯，将光束投射在刀具上，其阴影在刀具上方的显示屏上显示出来．通过移动头部（显示屏和灯头），在X方向和Z方向上的移动，使刀具阴影对准显示屏中心，这时，控制屏上通
CNC tool setting instrument is a CNC machining center, CNC lathe indispensable auxiliary tools. Its basic principle of operation is shown in Figure 1, which projects the beam onto the tool with a high-intensity spotlight under the tool, with the shading on the display above the tool. By moving the head (display and lamp) in the X and Z direction of the move, so that tool shadows aligned display center, this time on the control panel
