Abstract
Description
Technical Field
[0002] The utility model relates to the technical field of high-speed engraving and milling machines, in particular to a tool setter for a high-speed engraving and milling machine.
Background Art
[0004] The commercially available optoelectronic tool setters on the market have relatively large shapes and are suitable for large equipment such as CNC machining centers. Since the high-speed engraving and milling machine has a small workbench and a high spindle speed, it processes small parts with high precision. When using the purchased optoelectronic tool setter for tool setting, the workpiece and the optoelectronic tool setter may not be in full contact and tilt, resulting in tool setting errors and affecting the processing quality. To avoid abnormal quality, each time tool setting in the Z-axis direction, a ∮8mm milling cutter shank is used to slide back and forth between the workpiece and the tool setter. The tool setting reference is determined entirely by personal experience and feel, which is time-consuming and inefficient, increases the operation auxiliary time, and the quality is unstable.
