Black Aluminum Oxide Media Manufacturers Poland

Grinding wheel is the most important fused aluminium oxide grinding tool in grinding. Grinding wheel is a porous body which is made by pressing, drying and baking after adding binder into the abrasive. The grinding wheel is one of the most widely used grinding tools. It can be used for high-speed rotation, rough grinding, semi-fine grinding, 150 grit aluminum oxide fine grinding, slotting and cutting of the outer circle, inner circle, plane and various profiles of metal or non-metal workpieces.

brown fused aluminum oxide wheel is the most important grinding tool in grinding. Brown corundum grinding wheel is made of brown corundum abrasives and binders by pressing, drying and baking, loose disc-shaped and wheel shaped abrasives. The material used to bond abrasive in white aluminum oxide abrasive 220 grit grinding wheel is called binder. The performance of binder determines the strength, impact resistance, heat resistance and corrosion resistance of grinding wheel.


Because of the different binders, the characteristics of white fused alumina wheel are very different, so it has an important impact on the grinding quality, productivity and economy. At present, there are four kinds of binders: ceramic, resin, rubber and metal. If the bond of the brown corundum wheel is ceramic bond, it is called ceramic white aluminum oxide blast media wheel. The ceramic bond has good heat resistance, corrosion resistance, large porosity and easy to maintain the profile.


It is suitable for various form grinding, gear grinding and thread grinding with V < 35m / s. There is a kind of ceramic white alumina grinding wheel to increase the strength and hardness of the brown corundum grinding wheel and improve its performance. According to the above formula, each component is put into the mixer, mixed for 1-2 hours, and fully mixed; the mixture is poured into the mold, then the mold is put into the aluminium oxide blasting press for pressing, and the mold is heated at the same time. 


The ceramic white aluminum oxide grinding wheel is characterized in that it is made of the following weight parts of raw materials: brown corundum abrasive 40-50, cross corundum abrasive 10-15, garnet sand 3-8, tungsten powder 2-3, walnut shell grain 1-3, hard cool acid zinc 2-3, glycerol triglyceride cool 1-2, limestone 5-10, bentonite 5-10, Yingshi 3-6, quartz sand 2-5. The weight of each raw material component of the ceramic aluminium oxide grit suppliers grinding wheel is as follows:


Raw material: pink corundum abrasive, zirconium corundum abrasive, garnet sand, tungsten powder, walnut grain, zinc stearate, glycerate, limestone, bentonite, fluorite, quartz sand. The limestone, bentonite, Yingshi and quartz sand are melted at a high temperature of 2600-3000 ℃, and the ball is ground into nano ceramic powder after cooling, which can become a ceramic bond. The preparation method of the ceramic pink fused alumina grinding wheel is characterized in that the following steps are included:


First, 1-2 MPa is pre pressurized, the white corundum heating temperature of the upper and lower plates of the press is 300-350 ℃, the time is 2-4 minutes, then the pressure is boosted to 11-12 MPa, the pressure is maintained for 3-5 minutes, and then the treatment temperature is raised to 720-750 ℃, and the temperature is kept for 2-3 hours; Then natural cooling to 40-450 ℃, and heating to 1210-1250 ℃ at 3-5 ℃ per minute, and white fused aluminium oxide heat preservation for 6-7 hours;
