Worm and gear grinding wheel

“SG” is Seed Gal. Abrasive hardness, single abrasive containing numerous sharp Angle, can effectively improve the fine cutting force and reduce the number of refurbishment to a minimum. Compared with ordinary corundum grinding wheel, it has good shape preserving property, strong sharpness, anti-clogging, easy to burn workpiece, high abrasion ratio and less dressing. Used for alloy tool steel, high speed tool steel, heat resistant steel, bearing steel, stainless steel and all other hard grinding materials which are not easily ground by ordinary abrasive wheel and the metal material whose surface has been treated by special process.

Worm grinding wheel and gear single/double bevel grinding wheel with uniform structure, good balance performance, good tooth shape of grinding gear, no burn, no crack, high grinding efficiency.

Worm grinding wheel is mainly used for high precision grinding of spur gear, helical gear, bevel gear, crankshaft, worm wheel and worm, etc. It has the characteristics of good shape retention, high gear grinding accuracy and high productivity. Worm grinding wheel is mainly used for high precision grinding of spur gear, helical gear, bevel gear, crankshaft, worm wheel and worm, etc. It has the characteristics of good shape retention, high gear grinding accuracy and high productivity.

Gear single/double bevel grinding wheel is mainly used for grinding inner and outer gears of straight teeth and thread grinding and cutting edge grinding of multi-blade tools. Double bevel wheel is mainly used for grinding tooth surface of gear and single thread。Single bevel is used for grinding all kinds of sawtooth, reamer, milling cutter, gear shaper and so on.

The general principle of grinding wheel hardness is: when processing soft metal, hard grinding wheel is selected in order to avoid the abrasive falling off too early. When processing hard metal, soft grinding wheel is selected in order to make blunt abrasive particles fall off in time, thus revealing new abrasive particles with sharp edges and corners. The former is because when grinding soft materials, the working abrasive particles of the grinding wheel wear very slowly and do not need to be detached too early. The latter is because when grinding hard materials, the working grains of the grinding wheel wear faster and need to be updated quickly.

In order to ensure the precision and roughness of grinding, a slightly harder wheel should be used. The workpiece material thermal conductivity is poor, easy to burn and crack (such as grinding hard alloy), the selected grinding wheel should be soft.

Advantages of worm grinding wheel:

1. High hardness, low grinding temperature, low wear rate of dressing tool

2. Higher edge stability

3. Improve the damping performance during grinding and make it difficult to crack.

4. The abrasive is sharp and has high hardness, good heat resistance and toughness

5. Uniform structure, good shape of grinding wheel, high durability, no burn work, high grinding accuracy.

6. High grinding efficiency, improve the processing efficiency, reduce the cost

Higher porosity, stronger grinding capacity, better chip removal capacity
