CNC Router can be divided into manual tool setting and automatic tool setting. Automatic tool setting machines are generally equipped with tool magazines, row tool changers or disc tool changers. The automatic tool setting instrument is controlled by software, which automatically adjusts the initial position of the tool and the position of the engraved workpiece. Manual tool setting requires the operator to manually adjust the position of the processed object with a tool setting block.

The function of the tool setting instrument on the board CNC Router is to automatically adjust the initial position of the tool and the position of the engraved object, but this work is generally performed by skilled workers manually, so the tool setting instrument does not have high precision. After in-depth research, this technology can only perform simple tool setting, but cannot perform high-precision tool setting.
The market is generally a single-head fixed-spindle CNC Router. If it is necessary to complete engraving, cutting, and side drilling at the same time during processing, then a multi-process CNC Router is required, which is more cost-effective than an automatic tool-changing CNC Router. If you want to improve the efficiency of mass production, you generally choose a multi-head CNC Router.
