1. ceramic grinding stone: ceramic grinding stones have larger cutting force, suitable for rough grinding and fine grinding. Fine grinding… Equal treatment; porcelain grinding stone has almost no cutting force, and is suitable for polishing and mirror processing.
2. metal polishing media: usually copper, steel, stainless steel, aluminum alloy… The material and powder are the main materials, and they are not used for polishing. They are mainly used for polishing and grinding metal parts.
3. plastic grinding stones: generally used for soft hardness parts, such as zinc, aluminum, copper alloy, plastic injection, acrylic, Boli… This kind of workpiece.
Two, the choice and use of grinding stone:
1. shape size: according to the shape and size of the grooves, corners, corners, holes and holes of the workpiece, the shape and size of the grinding stone are chosen. The grinding effect is good and the grinding stone can not be stuck into the hole of the workpiece. Meanwhile, the convenience of the grinding must be taken into account.
2. material: according to the material, hardness and density of the workpiece. To determine the material of the grinding stone.
3. fineness: according to the process of workpiece, such as rough grinding, fine grinding, polishing. And so on, different surface requirements to choose different kinds of grinding stones.
Three. Note:
1. relative to the size and weight of the workpiece: if the size and weight of the grinding stone and the workpiece are not fit properly, the grinding stone will not be able to drive the workpiece, and the workpiece is aggregated and collided with each other.
2. proportions: the proportion of grinding stone and workpiece is considered 3:1 according to the quality and processing cost required by the workpiece. It is usually required for fine grinding, and the proportion of 6:1 can be used.
3. replenish the opportunity: regularly add new grinding stones, including the amount of wear and the total amount of stone grinding.
4. update time: when most of the grinding stone is small because of the wear and tear, it is easy to insert the whole new batch into the hole of the workpiece. However, the new grinding stone must be grinded out of the rough edge in the working groove in order to avoid injury to the surface of the workpiece.
