What is the accuracy of machine tools in general?

Different manufacturers and brands of machine tools have different accuracy. Please consult the manufacturer or refer to the product manual for details. At present, the accuracy of CNC machine tools in China reaches 0.0 1mm, while the advanced countries in the world can achieve the accuracy of 0.0001mm.

The best CNC machine tools in China are all in military factories, not to mention micron (one thousandth of a millimeter), 0. 1 micron to 0.0 1 micron, but the utilization rate of CNC machine tools in domestic military factories is often not high, and they are often used only for one process. Also, the penetration rate of CNC machine tools in China is very low, and there are a large number of ordinary machine tools.

Machine tool accuracy is divided into machine tool machining accuracy and machine tool static accuracy; The machining accuracy of machine tool refers to the dimensional accuracy, shape accuracy and position accuracy of the machined parts; The static accuracy of machine tool refers to the geometric accuracy, motion accuracy, transmission accuracy and positioning accuracy of machine tool in no-load state.
