A chemically assisted superabrasive metal bond grinding wheel sharpening device

Abstract

A chemically assisted superabrasive metal bond grinding wheel sharpening device, including a grinding machine, a grinding fluid injection device, a grinding fluid mixing and stirring device, a grinding fluid circulation filter device and a grinding fluid shortage alarm device, the grinding fluid The injection device sprays the grinding fluid on the surface of the grinding wheel through the nozzle through the pressurized pump; the grinding fluid mixing and stirring device quantitatively adds the oxidant to the grinding fluid and fully mixes the oxidant and the grinding fluid; the grinding fluid circulates The filter device circulates the grinding fluid during the grinding process and filters out impurities in the grinding fluid after grinding; the insufficient grinding fluid alarm device will drive the alarm switch when the grinding fluid in the grinding fluid tank is insufficient Start the alarm device to alarm. The invention solves the problem that a hard layer is formed on the surface of the grinding wheel in the current electric spark dressing and the subsequent grinding effect is deteriorated, and the problem that the on-line electrolytic dressing is not suitable for dressing the coarse-grained grinding wheel.

Description

technical field [0001] The invention relates to the technical field of grinding, in particular to a chemically assisted superhard abrasive metal bond grinding wheel sharpening device. Background technique [0002] At present, superabrasive grinding wheels are widely used in the field of mechanical processing due to their excellent grinding performance. In the grinding process of grinding wheels, when the hardness of the grinding wheel is relatively large, the binder has a relatively large holding force on the abrasive particles, and the sharp peak of the abrasive particles is worn after the wear. It is not easy to fall off by itself, so that the chip groove is blocked and the grinding performance of the grinding wheel is reduced. Therefore, the grinding wheel needs to be dressed to achieve good grinding performance. The two processes of grinding wheel dressing are shaping and sharpening. The surface is rounded to reduce the parallelism between the surface of the abrasive gra...

Problems solved by technology

[0005] In order to overcome the deficiencies of the prior art, the present invention provides a chemically assisted superabrasive metal bond grinding wheel sharpening device, which is an online sharpening device that sprays strong oxidative grinding fluid onto the surface of a superhard abrasive metal bond grinding wheel. The sharp device solves the problem that the current EDM dressing will form a hard layer on the surface of the grinding wheel, which will deteriorate the subsequent grinding effect and the problem that online electrolytic dressing is not suitable for dressing coarse-grained grinding wheels.
