What Are The Characteristics Of CNC Machine Tools Compared With Traditional Machine Tools?

Jul. 25, 2019

1. With a high degree of flexibility

Machining parts on CNC Machine Tool depends mainly on the machining program. It is different from ordinary machine tools. It does not need to be manufactured, many molds and fixtures are replaced, and the machine tool does not need to be re-adjusted frequently. Therefore, CNC machine tools are suitable for occasions where parts are frequently replaced, that is, suitable for single-piece, small-volume production and new product development, thereby shortening the production preparation cycle and saving a lot of process equipment costs.

2. High processing accuracy

The machining accuracy of CNC machine tools is generally 0.05-0.1MM. The CNC machine tools are controlled in the form of digital signals. Each time a numerical control device outputs a pulse signal, the moving parts of the machine tool move a pulse equivalent (generally 0.001MM), and the machine tool advances. The average error of the backlash and the screw pitch of the transmission chain can be compensated by the numerical control device. Therefore, the positioning accuracy of the numerically controlled machine tool is relatively high.

3. Processing quality is stable and reliable

Machining the same batch of parts, using the same tool and machining program under the same machining conditions, the tool's path is exactly the same, the parts have good consistency and the quality is stable.

4. High productivity

High-Speed CNC Machine Tool can effectively reduce the machining time and auxiliary time of parts. The range of spindle sound speed and feed rate of CNC machine tools is large, which allows the machine to perform powerful cutting with large cutting amount. CNC machine tools are entering the era of high-speed machining, and the rapid movement and positioning of moving parts of CNC machine tools and high-speed machining have greatly improved productivity. In addition, it can be used in combination with the tool magazine of the machining center to achieve continuous processing of multiple processes on one machine, reducing the turnaround time between the semi-finished products and increasing productivity.
