Problems solved by technology

[0002] After the taper hole of the machine tool spindle is worn, it is usually repaired with a manual electric grinding head. The traditional method and repair equipment are low in efficiency and poor in accuracy. usage of;
[0003] There are certain disadvantages in the use of existing machine tool taper hole precision repairing instruments. First, the work efficiency is low, the speed of the electric spindle is not high, and the work feed is not controlled by digital control to adjust the work feed rate. Secondly, the accuracy is poor, and the working time It can’t provide stable support, can’t reduce the vibration, the speed is unstable, and the rotation accuracy is low. Finally, it can’t adapt to large and small models, vertical and horizontal models, which has a certain impact on people’s use process. For this reason, we A new type of portable machine tool taper hole precision repairing instrument is proposed
