3D printing grinding wheel with cooling channels, laser 3D printer and preparation method of 3D printing grinding wheel

Abstract

The invention discloses a 3D printing grinding wheel with cooling channels, a laser 3D printer and a preparation method of the 3D printing grinding wheel and relates to the field of grinding wheel manufacturing. The 3D printing grinding wheel is provided with the internal cooling channels. Each internal cooling channel is formed by connecting micro channels communicating with one another. The internal cooling channels are optimized and designed through three-dimensional modeling software. The 3D printing grinding wheel is formed by conducting 3D printing forming on metallic bond and superhardabrasive materials. According to the 3D printing grinding wheel manufactured by the laser 3D printer through the preparation method, the metallic bond and superhard abrasive material grinding wheel with the internal cooling channels is manufactured through the laser 3D printing technology. The internal cooling channels are formed by connecting micro channels communicating with one another. In thegrinding process, the grinding wheel can effectively improve the permeability and wettability of grinding fluid, improve heat dissipation in a grinding zone, reduce grinding burns and improve the quality of ground surfaces.

Description

technical field [0001] The invention relates to the field of grinding wheel manufacturing, in particular to a 3D printing grinding wheel with a cooling channel, a laser 3D printer and a preparation method. Background technique [0002] With the rapid development of high-speed precision grinding technology, the industry has put forward higher requirements for superhard grinding wheels, and resin and vitrified bond grinding wheels can no longer fully meet the requirements. The metal bonded grinding wheel is widely used in engineering ceramics, optical glass, hard alloy, etc. Grinding of difficult-to-machine materials. At present, metal bonded grinding wheels are sintered and formed by traditional techniques. [0003] The traditional sintered metal bond superabrasive grinding wheel, because the bond is relatively dense, there are few or almost no pores in the grinding wheel, poor self-sharpening, small chip space, easy to block the surface of the grinding wheel, poor cooling ...
