Micro-scale grinding online electrolytic dressing device and method thereof

Abstract

The invention discloses a micro-scale grinding online electrolytic dressing device which comprises a pulse power supply, a laser micrometer dial, a grinding wheel, a computer, a numerical control system, a three-dimensional numerical control platform and a rotating electrode. The laser micrometer dial in the electrolytic dressing device measures the rotation accuracy of the grinding wheel in an online manner and transmits the measured rotation accuracy of the grinding wheel to the computer, the rotation accuracy of the grinding wheel is processed and analyzed by the computer to obtain a rotation error of the grinding wheel, the rotation error is transmitted into the numerical control system to perform interpolation operation, an interpolation operation result is used for controlling the three-dimensional numerical control platform to drive the rotating electrode to move in an interpolating manner along an axial profile of the grinding wheel, the grinding wheel vertically and slowly feeds downwards, so that pulse sparks are continuously generated between the rotating electrode and metal bond of the grinding wheel, and the grinding wheel is dressed by discharging. The micro-scale grinding online electrolytic dressing device can automatically adjust the position of the rotating electrode to realize micro-scale online electrolytic dressing, and has the advantages of high efficiency, automation, simplicity and convenience in operation and the like.

AI Technical Summary

Problems solved by technology

In the micro-scale grinding process, the surface microstructure shape of the microstructure will seriously restrict the geometrical dimensions of the diamond grinding wheel, so the grinding wheel usually has a tiny profile structure, which makes the grinding wheel easy to wear during the grinding process, so the dressing of the grinding wheel It is very important, but in the prior art, the precision dressing of the grinding wheel needs to be manually removed from the grinding machine, and the grinding wheel is repaired in other places, and then installed on the grinding machine after the repair.
