Cutting tool machining grinding wheel

Abstract

The invention discloses a cutting tool machining grinding wheel. The cutting tool machining grinding wheel comprises a grinding wheel base and a grinding material layer located on the grinding wheel base. The grinding material layer comprises the following components including, by mass, 15%-19% of diamond, 3%-7% of silicon carbide, 4%-6% of silicon dioxide, 1%-4% of resin powder, 2%-6% of pyrite powder, 1%-3% of lime, 9%-11% of a binder, 2%-3% of a pore former and the balance auxiliary grinding materials. Ti2O/Al2O3 film layer coated diamond is adopted as the diamond. A rubber binder is adopted as the binder. Raw materials of the rubber binder comprise, by mass, 11-18 parts of boric acid, 3-8 parts of sodium carbonate, 2-4 parts of lithium hydroxide, 11-18 parts of sodium oxide, 10-19 parts of silicon dioxide, 20-28 parts of alcohol soluble acrylate resin and 4-9 parts of butyl acrylate. One of ammonium bicarbonate and hollow alumina balls is adopted as the pore former. One of microcrystal corundum, microcrystal, black silicon carbide and black silicon carbide is adopted as the auxiliary grinding materials.

Description

technical field [0001] The invention relates to the technical field of grinding wheels, in particular to a grinding wheel for processing cutting tools. Background technique [0002] Grinding wheel, also known as bonded abrasive, is a bonded abrasive that consolidates ordinary abrasives into a certain shape (mostly round, with a through hole in the center) with a certain strength. It is generally composed of abrasives, binders and pores. These three parts are often called the three elements of bonded abrasives. Grinding wheels are the most widely used abrasive tools. They rotate at high speeds and can be used on metals or the outer circle, inner circle, plane and various profiles of non-metallic workpieces, etc., for rough grinding, semi-finishing and fine grinding, as well as slotting and cutting; the grinding wheel in the prior art can be used for long-term grinding. The waste is serious, the replacement frequency is high, and the work efficiency is not high, which has bro...

It is generally composed of abrasives, binders and pores. These three parts are often called the three elements of bonded abrasives. Grinding wheels are the most widely used abrasive tools. They rotate at high speeds and can be used on metals or the outer circle, inner circle, plane and various profiles of non-metallic workpieces, etc., for rough grinding, semi-finishing and fine grinding, as well as slotting and cutting; the grinding wheel in the prior art can be used for long-term grinding. The waste is serious, the replacement frequency is high, and the work efficiency is not high, which has brought great troubles to the staff. In order to prolong the use time and service life of the grinding wheel, reduce the scrap rate and production cost, and improve work efficiency, the present invention proposes grinding wheel
