Description

Technical Field

[0001] The utility model relates to the technical field of ball screw processing, in particular to a device for tempering the shaft end of a ball screw. Background Art

[0002] In modern precision machinery and CNC machine tools, ball screws, as key transmission components, undertake the important function of converting rotary motion into linear motion or converting linear motion into rotary motion. The performance of ball screws directly affects the positioning accuracy, repeatability and working stability of machine tools;
