Steel-paper sanding discs are also called steel-paper grinding discs, high-speed grinding discs and grinding discs, among which steel-paper sanding discs and steel-grinding discs are used more often. A disc-shaped coated abrasive formed by bonding with resin or other synthetic binders.
Steel-paper sanding disc is one of the most distinctive products in coated abrasives. Its substrate has strong rigidity and toughness. Therefore, its use and manufacture have some outstanding characteristics compared with other varieties. These characteristics are as follows:
(1) Simple production and short cycle
The production mechanization of steel fiber discs is very low, and it is simple mechanical or manual production, so not only the facilities are simple, but also the operation is easy to master. For a batch of products, the production cycle is short, but the production output is not much, that is, the production efficiency is low.
(2) High strength and good toughness
The base of the steel-paper abrasive disc has high strength and good toughness. In addition, the binder it uses is a binder with high bonding strength, so it is suitable for grinding workpieces under high speed and high load, and its linear speed can reach 100— 130 m/s.
(3) Good rigidity and completely reliable use
The steel fiber disc has both good rigidity and certain elasticity. Although the steel paper as the base has poor flexibility, it has high strength and high toughness. Under the action of high-speed rotation and high load, it is not easy to be broken, and the processing process will not produce the danger that may occur during grinding wheel processing. Use safer and more reliable tools.
(4) Easy to use and flexible, good processing effect
The steel fiber disc is small in size and light in weight. It is installed in a portable fan. This kind of machine is small and flexible, and it is very convenient to operate. It can grind a large surface and is also suitable for grinding irregular surfaces. very good.
(5) There are many specifications and varieties and a wide range of uses
The steel fiber disc can be divided into disc shape, polygon shape and lotus leaf shape according to the shape. The steel fiber disc can be divided into multiple specifications according to the size of the hole diameter and the outer diameter of the outer circle.
