Green silicon carbide 220 # 400 # 800 # for solid carbide tools
Green silicon carbide abrasive is an important participant in the production of solid carbide tools. It is suitable for the passivation of blade edges, and surface treatment before cemented carbide powder coating spraying. And polishing inserts or drills after powder coating.
Solid carbide cutters are usually made from metallurgical powders such as tungsten carbide, cobalt powder, titanium carbide, molybdenum alloy, nickel alloy, etc. For this type of material, green silicon carbide abrasive can play a good grinding role. According to the different materials, the HV hardness of hard alloys ranges from 900 to 2000. High hardness tungsten carbide HV2600, green silicon carbide Vickers hardness HV3280-3400. Although the hardness of green silicon carbide is not as good as superhard material and diamond, it is a good choice in terms of cost performance.
In the production process of solid carbide inserts or drills, passivation treatment is required on the cutting edge to enhance the strength of the cutting edge and reduce the cutting edge gap. Thus achieving the goal of extending service life and improving tool quality. Green silicon carbide abrasive with strong grinding ability is usually for sandblasting and passivating the edges of solid carbide tools. The commonly used brands are green silicon carbide 320 # and green silicon carbide 400 #.
Tools coated with cemented carbide coatings have better cutting performance. In order to make the coating adhere more firmly to the alloy substrate. It usually take surface treatment on the substrate. The increase in surface roughness of the substrate can improve the holding force of the coating. The commonly used sandblasting abrasives for this purpose are green silicon carbide 46 #, green silicon carbide 120 #, and green silicon carbide 220 #.
After polishing and beautifying the solid carbide cutters, the surface presents a beautiful metallic luster. It can enhance the appearance and grade of the product. In this application, commonly used green silicon carbide abrasives are models such as 600 # 800 #.
