Plane millstone filling system with self-sharpening function

Abstract

The invention discloses a plane millstone filling system with a self-sharpening function. The plane millstone filling system is prepared from the following raw materials: epoxy resin, a curing agent, microcrystal fused alumina, chromium sesquioxide and absolute ethyl alcohol. An inorganic abrasive material in a filled layer has a micro-crushing function and can be automatically crushed during passivation in the milling process to generate a novel milling cutting edge, so that the self-sharpening performance of the filled layer is improved. When the plane millstone filling system is used for filling a gap of a plane millstone, the preparation process is simple, no special recruitments for raw materials are required, the leveling property is good during filling, and a filler can be in favorable contact with an abrasive block; the filled plane millstone is favorable in heat radiating capability, strength and rigidity, capable of favorably solving the problem of scrap and workpiece burning in the existing milling process, prolonging the finishing intervals and further increasing the milling efficiency and suitable for industrial production and application.

Description

technical field [0001] The invention relates to a grinding disc filling system, in particular to a plane grinding disc filling system with a self-sharpening function, and belongs to the technical field of grinding parts preparation. Background technique [0002] With the development of science and technology, CNC ultra-precision grinding machines, high-speed and high-precision crankshaft grinding machines and camshaft grinding machines, various high-precision and high-speed special grinding machines, etc., have become one of the key development areas in my country, and the improvement of processing efficiency is the development of CNC grinding machines. The important direction requires the cutting force of the grinding wheel to be good and sharp; it is also required to have good shape retention and continuous processing; at the same time, the grinding wheel is required to be resistant to high heat and strong extrusion. [0003] The double-end surface grinding machine is a hig...

AI Technical Summary

Problems solved by technology

Vitrified bond double-end grinding discs are generally made by bonding small round or regular hexagonal grinding blocks to the metal substrate. There is a certain gap between the small grinding blocks. If it is used to process small-sized workpieces (diameter less than 40mm), the gap between the grinding blocks must be filled, if not filled, it will easily lead to collision between the workpiece and the grinding block

At present, the material used to fill double-ended grinding discs is generally pure epoxy resin. Filling with pure epoxy resin will reduce the sharpness of the grinding disc to a certain extent, making the edge-out performance of the grinding disc poor, the grinding process efficiency is not high, and it is easy to produce grinding discs. Surface damage such as chip sticking or burns on the workpiece surface affects the processing quality of the workpiece, and the dressing interval of the grinding disc is relatively short, requiring frequent dressing of the grinding disc
