The invention discloses a grinding device and a grinding method for an inner hole of a main shaft of a numerical control machine tool. The grinding device comprises a pneumatic grinding machine, a movable support, a fixed support and a bottom plate which are sequentially arranged from top to bottom, the fixed support is arranged on the outer side of the movable support in a sleeved mode, the bottom plate is fixed at the bottom part of the fixed support, a plurality of first screws and a second screw are arranged on the side wall of the fixed support in a penetrating mode, the movable support is fixed on the upper part of the fixed support, the pneumatic grinding machine is fixed on the movable support, a pneumatic grinding head is arranged at the top end of the pneumatic grinding machine, an air pipe connector of the pneumatic grinding machine is connected with an air pipe connected with an external air source. The grinding device has the advantages of being simple in structure, stable and reliable, low in manufacturing cost and easy to carry, and grinding precision of the inner hole of the main shaft of the numerical control machine tool can be guaranteed; and the grinding method has the advantages that operation is flexible and convenient, under the condition that the main shaft is not detached, the fast grinding of the inner hole of the main shaft can be realized, the halt waiting time is shortened, the grinding process is completed by automatic operation of machine tool, so that the grinding reliability is good, and the precision is high.
Description
technical field [0001] The invention relates to a grinding device and a grinding method, in particular to a grinding device and a grinding method for the inner hole of a spindle of a numerically controlled machine tool. Background technique [0002] After many years of use of CNC machine tools, due to the complex processing environment or improper daily maintenance of equipment, it is prone to the phenomenon of out-of-tolerance precision of the inner hole of the machine tool spindle, which directly leads to poor contact between the cutting tool handle and the inner hole of the spindle of the CNC machine tool. The cutting chatter marks are obvious, which affects the processing quality of the parts. [0003] The traditional maintenance method is to disassemble the spindle of the CNC machine tool, and then send the spindle to an enterprise with processing capabilities for maintenance. This method has two disadvantages: 1. The cost of spindle repair is high; 2. It takes a long ...
