Manufacturing method for 3D printing diamond grinding wheel with abrasive particles arranged regularly

Abstract

The invention belongs to the technical field of grinding machining and 3D printing and relates to a manufacturing method for a diamond grinding wheel with abrasive particles arranged regularly. Related devices mainly comprise a movement control platform, a grinding wheel printing system and a 3D printing grinding wheel. The movement control platform comprises a base, a rotation movement table, a lifting platform, a horizontal-moving platform, a movement control device and a supporting frame. The grinding wheel printing system comprises a diamond abrasive particle nozzle, a conveying pipe I, a diamond abrasive particle box, a nozzle supporting plate, an air pipe I, an air valve I, an air valve III, an air source, an air valve II, an air pipe II, a metal bonding agent powder box, a conveying pipe II, an air pipe III, a laser source, a laser optical path, a laser beam, a bonding agent nozzle and airflow. The 3D printing grinding wheel comprises a grinding wheel base body, a metal bonding agent and the diamond abrasive particles. The abrasive particles can be regularly arranged in the grinding wheel, when the grinding wheel of this kind is ground, the machined surface is high in quality, grinding efficiency is high, grinding force is even, and the service life of the grinding wheel is prolonged. Thus, the manufacturing technology of the special-shaped grinding wheel is simplified, platform constructing is convenient, and operation is easy and convenient.

Description

technical field [0001] The invention belongs to the technical field of grinding processing and 3D printing, and relates to a method for preparing a diamond grinding wheel suitable for regular arrangement of abrasive grains. Background technique [0002] In recent years, with the rapid development of high-speed, precision and ultra-precision grinding technology, higher requirements have been placed on diamond grinding wheels, and ceramic and resin bonded grinding wheels can no longer fully meet the needs of modern production. Metal bonded grinding wheels are widely used in difficult-to-process engineering ceramics, optical glass, and hard alloys because of their strong holding force, high bonding strength, good wear resistance, good formability, long life, and large grinding. Grinding of materials. In addition, at present, the forming grinding wheel grinding method in which the profiling surface matches the workpiece is mainly used to carry out precision forming processing o...
