Abstract

The invention discloses a grinding tool with high tangential grinding force and low normal grinding force, and belongs to the technical field of efficient and precise grinding of materials difficult to machine. In order to solve the problems that in traditional grinding machining, the high tangential grinding force and the low normal grinding force cause low material removal rate, grinding tool and workpiece damage and deformation, grinding vibration, grinding wheel blockage, poor workpiece surface integrity, frequent grinding burning and the like, the novel grinding tool is provided; and a similar body armor principle is used, abrasive particles generate a constellation effect under impulse loads, the tangential grinding force instantly increases, and the normal grinding force instantly decreases. The novel grinding tool is composed of three parts including a matching ring, a base ring and an abrasive material layer with the abrasive particle constellation effect. The abrasive material layer is bonded to the base ring through a heat bonding method, the base ring is assembled to the matching ring, and therefore the novel high-precision high-self-sharpening grinding tool is manufactured. According to the grinding tool, high-efficiency, high-precision and high-surface-integrity grinding machining of the difficult-to-machine materials such as crisp and hard materials or aerospace composite materials can be achieved with the high tangential grinding force and the low normal grinding force.

Description

technical field [0001] The invention relates to a new type of grinding tool, especially a grinding tool with high tangential force and low normal force for difficult-to-machine materials, and belongs to the technical field of high-efficiency and precision grinding of difficult-to-machine materials. [0002] technical background [0003] Traditional grinding technology uses abrasive tools with many fine and extremely hard abrasives on the surface to process the surface of the workpiece. Due to the large negative rake angle and the arc radius of the cutting edge of the abrasive tool, the cutting depth is very small, and the surface material of the workpiece produces elastic deformation. With the increase of the intrusion depth, the pressure between the abrasive grains and the surface of the workpiece gradually increases, and the The material begins to produce plastic deformation, and the cutting depth continues to increase, and part of the material on the surface of the workpie...
