Precision of machine tool

The shape and position errors such as radial runout, end runout and inconsistent rolling body diameter of high precision bearings of machine tools will seriously affect the accuracy of the spindle system and its machined parts. Therefore, the bearing accuracy used in the spindle of precision machine tools is P5 or higher. For the spindle support of high-speed and high-precision machine tools such as CNC machine tools and machining centers, it is necessary to select P4 or higher precision grades and high precision grades. Bearing.
The spindle bearing of machine tool is the spindle bearing of precision machine tool and similar equipment. It guarantees the working accuracy and performance of precision machine tool.
