Abstract

The invention relates to a grinding wheel sharpening device based on a microwave-induced graphite particle bursting effect. The grinding wheel sharpening device comprises a working base table, an electric spindle system, a grinding wheel mounting device and a microwave generating system; a to-be-sharpened grinding wheel is mounted on the working base table through the grinding wheel mounting device, and the electric spindle system is connected with the grinding wheel; the microwave generating system comprises a jetting device and a microwave generating element, and the jetting device and the microwave generating element are oppositely arranged on the two sides of the grinding wheel; the jetting device is used for shooting graphite particles to a grinding area on the surface of the grinding wheel; and the electric spindle system drives the grinding wheel to rotate, so that the grinding area, covered with the graphite particles, on the surface of the grinding wheel is rotated to the position below a heating opening of the microwave generating element, the microwave generating element heats the graphite particles in the grinding area, and the graphite particles are heated to burst to sharpen the grinding wheel. According to the grinding wheel sharpening device, the microwave-induced graphite particle bursting effect is utilized for efficiently completing high-precision sharpening of the grinding wheel, safety and reliability are achieved, efficiency is high, and practicability is high.

Description

technical field

[0001] The invention relates to a numerical control device for grinding wheel sharpening, in particular to a grinding wheel sharpening device based on the bursting effect of microwave-induced graphite particles, which is suitable for processing high-precision precision tool equipment. Background technique

[0002] At present, there are many methods of grinding wheel sharpening, such as free abrasive sharpening, laser sharpening and high-pressure jet sharpening, etc., but due to the influence of the working environment and equipment, these methods are difficult to popularize and apply, and are really used in industrial production. The sharpening methods are mainly oilstone sharpening method and dressing wheel cutting sharpening method. However, the whetstone dressing method has the disadvantage of not being able to obtain a large protruding height of the abrasive grains, so it cannot be used for grinding and sharpening of the grinding wheel with a large amount...
