Chemically-assisted super-hard abrasive metal bond grinding wheel dressing device

Abstract

The invention discloses a chemically-assisted super-hard abrasive metal bond grinding wheel dressing device. The device comprises a grinding machine, a grinding fluid spraying device, a grinding fluid mixing and stirring device, a grinding fluid circulating filtering device and a grinding fluid insufficiency alarm device; the grinding fluid spraying device sprays grinding fluid to the surface of a grinding wheel through a pressure pump and a spray head; the grinding fluid mixing and stirring device is used for quantitatively adding an oxidizing agent into the grinding fluid and sufficiently mixing the oxidizing agent with the grinding fluid; the grinding fluid circulating filtering device enables grinding fluid to circularly flow in the grinding process and filters impurities in the grinding fluid after grinding; and when the grinding fluid in the grinding fluid tank is insufficient, the grinding fluid shortage alarm device can drive the alarm switch to start the alarm device to give an alarm. The method solves the problems that a hard layer is formed on the surface of the grinding wheel by an electric spark method at present, so that the subsequent grinding effect becomes poor, and 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 because of their excellent grinding performance. It is not easy to fall off by itself, which will block the chip pocket and reduce the grinding performance of the grinding wheel. Therefore, it is necessary to dress the grinding wheel 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 grain and the generatrix of the grinding wheel during the grinding process of the grinding wheel. Sharpening refers to exposing the new abrasive grains of the grinding wheel to form a new cutting edge, so that the grinding wheel can obtain good grin...

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.
