Abstract

The invention discloses a metal bonding agent 3D printing grinding wheel with a random porous structure and a device and method. The metal bonding agent 3D printing grinding wheel comprises a grindingwheel base body and a grinding wheel grinding main body, wherein the grinding wheel grinding main body is arranged at the outer side of the grinding wheel base body in a sleeving manner. The grindingwheel grinding main body is formed through 3D printing and provided with the random porous structure and comprises a metal bonding agent and a superhard grinding material. The ratio of the volume ofthe random porous structure to the volume of the grinding wheel grinding main body ranges from 15% to 45%. By means of the metal bonding agent 3D printing grinding wheel, the porosity and chipping containing space of the metal bonding agent 3D printing grinding wheel can be greatly increased; heat dissipation of a grinding area is improved; grinding burns are reduced; and grinding surface qualityis improved.

Description

technical field [0001] The invention relates to the technical field of grinding, in particular to a metal bond 3D printing grinding wheel with a random porous structure, a device and a method. Background technique [0002] In related technologies, 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. [0003] However, the traditional sintered metal bond superabrasive grinding wheel has the following limitations: 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, and poor cooling performance , It is easy to burn the surface ...
