CNC machine tools in precision parts processing are indispensable equipment in modern manufacturing industry, which can efficiently and accurately complete various processing tasks. The positioning accuracy of the machine tool has a great impact on the machining quality, so it is very important to regularly detect and maintain the positioning accuracy of the machine tool. So, how do we detect the positioning accuracy of CNC machine tools?

First of all, the common method is to use a laser interferometer for detection. Laser interferometer is a kind of high precision measuring instrument, which can measure the position error of machine tool table. By placing the laser interferometer on the workbench, the laser beam is shot at the target, and the difference between the actual position and the theoretical position of the workbench is measured by the interference signal, so as to obtain the positioning accuracy of the machine tool.

Secondly, you can also use a test gauge for detection. The measuring gauge is a precision measuring tool that can measure the displacement and positioning error of the table. By placing the test gauge on the workbench, then moving the workbench and observing the pointer of the test gauge, the positioning accuracy of the machine tool can be judged.

In addition, the coordinate measuring instrument can also be used for detection. Coordinate measuring instrument is a kind of high precision measuring instrument, which can measure the displacement error of each axis of machine tool. By placing each axis of the machine tool on the coordinate measuring instrument, then moving the machine tool and observing the display result of the measuring instrument, the positioning accuracy of the machine tool is obtained.

Finally, a digital measuring instrument can also be used for detection. Digital measuring instrument is a kind of portable measuring instrument, which can measure the displacement error of machine tool in real time. By installing the digital measuring instrument on the machine tool, and then processing operation, observing the display result of the measuring instrument, the positioning accuracy of the machine tool is obtained.

In precision parts processing, the positioning accuracy of CNC machine tools can be detected by laser interferometer, test gauge, coordinate measuring instrument and digital measuring instrument. Through regular testing and maintenance, it can ensure the positioning accuracy of the machine tool, improve the processing quality, and provide stable and reliable support for the development of the manufacturing industry.
