What are the binding agents of the grinding wheel

2024-07-29

Ceramic bond is an inorganic bond, which has stable heat resistance, corrosion resistance and other properties, and small porosity. Ceramic bond grinding wheels are the most widely used. They have good performance in the grinding of ordinary carbon steel, alloy steel, stainless steel, cast iron, hard alloy and other materials. They have high grinding efficiency, low wear, but high brittleness. Severe vibration should be avoided in use; usually the speed does not exceed 35 m/s.
The resin binder is an organic binder. The resin binder grinding wheel has high strength and self-sharpening, and certain elasticity, but low heat resistance; it is used in rough grinding, waste grinding, cutting and free grinding such as grinding ingots and casting burrs. The production is simple and the process cycle is short. The working speed of the resin-bonded grinding wheel can be higher than 50 m/s, and it can also be made into a very thin shape. The scope of application is second only to ceramic bond grinding wheels,
In addition, the choice of grinding wheel also needs its specification size.

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.
