Abrasive of grinding wheel

2024-07-29

1, brown corundum has high hardness and toughness, so in grinding such as carbon steel, alloy steel, malleable cast iron, hard bronze and other high tensile strength metal, can show good grinding performance, more in the removal of a larger margin of rough grinding link, and the price is cheap;
2, white corundum relative to brown corundum, its hardness is higher, but the toughness is slightly lower, grinding process, abrasive fragile; therefore used for such as fine grinding hardened steel, high carbon steel, high speed steel, or grinding thin-walled parts manufacturing.
3. Black silicon carbide has high hardness and high sharpness; but its brittleness is low. It is used more in grinding low mechanical strength materials such as cast iron, brass, aluminum and refractory materials.
4, green silicon carbide abrasive sharpness and thermal conductivity are better, and the hardness and brittleness than black silicon carbide will be slightly higher, in the hard alloy, optical glass, ceramics and other hard brittle material grinding process used more.

Rotation direction of grinding wheel of grinding machine

2024-07-29

The direction of rotation of the grinding wheel of the grinder should be such that the debris flies downward away from the grinding wheel, which is usually counterclockwise. This arrangement ensures safety during operation and prevents wear debris or workpiece fragments from flying to the operator, thereby reducing the risk of accidents. In actual operation, it should be ensured that the rotation direction of the grinding wheel conforms to the safety regulations, and avoid standing in the opposite direction of the grinding wheel rotation to prevent fine particles from being ejected and ensure the safety of the operator.

Check the grinding wheel: Before use, carefully check the grinding wheel for cracks and confirm whether the installation is firm. Make sure that the grinding wheel has not suffered any damage and is installed correctly.

What is the grinding wheel used?

2024-07-29

Grinding wheel is a kind of tool used for grinding. It consolidates ordinary abrasives into a certain shape (mostly round, with a through hole in the center) by bonding agent, and has a certain strength of consolidated abrasives. The main components of the grinding wheel include abrasive, bond and pores, which are collectively referred to as the three elements of the fixed abrasive. There are many kinds of grinding wheels. According to the different binders, the common ones are ceramic (binder) grinding wheels, resin (binder) grinding wheels, rubber (binder) grinding wheels, etc. Grinding wheels are widely used and can be rotated at high speed for rough grinding, semi-fine grinding and fine grinding of metal or non-metal workpieces, as well as grooving and cutting operations. In industrial applications, grinding wheels can process the outer circle, inner circle, plane and various types of surfaces of the workpiece.
