1. High grinding efficiency
2. Has high wear resistance
3.Small grinding force and low grinding temperature
4. The ground workpiece has high precision and good surface quality
Cemented carbide, ceramics, glass, agate, gemstones, semiconductor materials, stones and other non-metallic hard and brittle materials and non-ferrous metal workpieces are suitable for processing with diamond grinding wheels.
The diamond grinding wheel is a surface grinding tool used for various types of refractory materials. This tool is designed to meet different needs. So there are different types and specifications. To make diamond wheels play their best role, we have to learn about diamond grinding wheels. Today we will take a look together: What are the advantages of diamond grinding wheels? Which materials are suitable for processing with diamond grinding wheels?
When grinding cemented carbide, its grinding efficiency is several times that of silicon carbide. When grinding W12 Cr4V4Mo high-speed steel with poor grinding performance, the average efficiency is increased by more than five times.
The wear resistance of diamond grinding wheels is very high, and the consumption of abrasive grains is very small, especially when grinding hard and brittle workpieces. This is most prominent. When using a diamond grinding wheel to grind hardened steel, its wear resistance is 100 to 200 times that of available abrasives; when grinding hard alloys, it is 5000 to 10,000 times that of general abrasives.
The hardness and wear resistance of diamond abrasive grains are very high, and the abrasive grains can stay sharp for a long time and are easy to cut into the workpiece. When using resin-bonded diamond grinding wheels to grind cemented carbide, the grinding force is only 1/4 to 1/5 of ordinary grinding wheels. The thermal conductivity of diamond is very high, 17.5 times that of silicon carbide, and the cutting heat is quickly transferred out, so the grinding temperature is low.
Grinding cemented carbide tools with a diamond grinding wheel, the roughness of the knife face and cutting edge is much lower than grinding with a boron carbide grinding wheel. The arc radius of the cutting edge is small, the blade is very sharp, and the tool's durability can be increased by 1 to 3 times. The roughness of the workpiece processed by the diamond grinding wheel is generally up to 0.1~0.025μm, which can improve the finish by 1~2 levels compared with the ordinary grinding wheel.
