1，Electrostatic sand planting

According to the principle of high-voltage electrostatic adsorption, The electrostatic sand planting belt can form a neatly arranged and uniformly distributed abrasive layer, and all the sharp end of the abrasive particles are all outwards, therefore, the cutting is sharp so that the grinding efficiency is higher.

2,  Joint belts

Joint belts are the main form of abrasive belts at present.

The joint belt is made by cutting, edging, joint bonding, and slitting of the original roll of the belt, according to different sizes. The length is not constricted. It can be any length. And the production is very convenient. Especially the current joint glue and joint process equipment has made the belt joint easily and efficiently. Even the whole part consistency has reached a very high level.

Open abrasive belt is another type of abrasive belt.

It is a small roll of abrasive belt formed by directly slitting the original rolled abrasive belt according to the size.

The open abrasive belt is very convenient to use. They are often used in fine-grained precision machinings, such as the grinding and polishing of the automobile engine camshafts, crankshafts, and precision external circular parts.

Normally the workpiece movement speed is high, and the belt speed is low, there is always a new abrasive in the grinding area to participate in the grinding, so the consistency of the grinding surface quality is very good.

In next chaper, we will continure on this topic.

Waiting for me there!
