White Aluminum Oxide 120 Grit Wholesale Price UK

Copper coated abrasives are used for white corundum dry grinding and tin coated abrasives for wet grinding. The coating of superhard abrasive particles has the following advantages. The abrasive strength is increased by 30% ~ 60%. RVD diamond and CBN are brittle materials. After being coated with a layer of copper or nickel film, the white aluminum oxide 120 grit brittleness can be improved and the impact of external force can be greater.

At the same time, during the plating process, the solution infiltrated into the cracks, pores and holes on the brown aluminum oxide blast media surface, thus repairing the defects and strengthening the RVD diamond and CBN particles. Metal coating has a good thermal barrier effect on RVD diamond and CBN. Phenolic resin modification is to add additives to change some properties of the resin. The formula of resin binder should be adjusted properly and the brown fused alumina grit concentration should be selected reasonably.


The wettability of the resin bond to the superhard material is improved, thus the adhesion of the resin bond to the white fused aluminum oxide 60 grit particles is improved, and the durability of the abrasive tools is increased. The results show that about 70% of the abrasive grains fall off directly when dry grinding the cemented carbide without coating, while coating RVD diamond and CBN abrasive can greatly improve the falling off state of the black silicon carbide suppliers grains.


The brown aluminium oxide manufacturer grinding heat generated in the grinding process is first transmitted to the metal film and then to the binder through the metal film. Therefore, the grinding heat accumulation is less, so that the probability of decomposition of resin bond around RVD diamond and CBN reaches the carbonization temperature is much less, which ensures the bond strength of resin bond to abrasive particles and can fully play the grinding role of aluminium oxide grit 24 mesh particles.


The brown fused alumina for grinding particle size of resin bonded superhard grinding tool is fine, and the coarse particle size will aggravate the wear of grinding wheel. Generally, the particle size is below 100um / 120um to micropowder. The concentration of resin abrasives is relatively low. Generally, the concentration of RVD diamond abrasives is 25% ~ 100%, the concentration of common black aluminium oxide is 75% ~ 100%; the concentration of CBN abrasives is 75% ~ 100%. Hardener is an important part of epoxy resin bond.


Coating metal can reduce the self sharpening of RVD diamond and CBN, thus increasing the white fused alumina power consumption of grinding machine by 10% ~ 20%. When the temperature is over 1300 ℃, the abrasive properties will decrease. High concentration of coarse grinding tools should be used for coarse grinding and low concentration of fine grinding tools should be used for pink alumina fine grinding. There are three types of epoxy resin: glycidyl epoxy resin, epoxide olefin and new epoxy resin.


Hardener can be divided into heating hardener and room temperature hardener according to the white aluminum oxide required temperature; according to the type of chemical structure, it can be divided into high abrasive conductivity, such as molybdenum, silver, graphite powder, etc.; used to promote hardening, such as Cao, MgO, etc.; used to improve the heat resistance of black silicon carbide factory, such as graphite powder, asbestos powder, clay powder, quartz powder, Fe) powder, etc.
