CNC machine tools are machines that use digital information to achieve automatic control. It compiles information related to the processing of parts (such as the size parameters of the relative motion trajectory between the workpiece and the tool, the process parameters of cutting, and various auxiliary operations) into a machining program sheet in a specified format using specified text, numbers, and symbols, and then inputs it into the CNC device through the control medium. After analysis and processing by the CNC device, Send out various signals and instructions corresponding to the processing program for automatic processing.

The overall price of ordinary machine tools is relatively cheap, making them more cost-effective in terms of production costs. The main advantage of ordinary machine tools is experience, and experienced operators who have received training on ordinary machine tools will excel in machining efficiency compared to novices using CNC.
