Grinding Wheel Product Attributes

Grinding wheel is a circular bonded abrasive with a through hole in the center made of abrasive and binder. The characteristics of the grinding wheel are determined by factors such as abrasive, particle size, hardness, binder, shape and size, which are introduced as follows.
Selection of abrasive
Abrasive is the main raw material for manufacturing grinding wheels, and it is responsible for cutting. Therefore, the abrasive must be sharp and have high hardness, good heat resistance and certain toughness.
Particle size and its selection
It refers to the size of abrasive particles. Particle size is divided into two categories: abrasive particles and micro powder. Abrasives with a particle size greater than 40μm are called abrasive particles. When grading by screening method, the particle size number is expressed by the number of holes per inch of the screen through which the abrasive particles pass. For example, 60# abrasive particles indicate that their size can just pass through a screen with 60 holes per inch. Abrasives with a particle size less than 40μm are called micro powder. When grading by microscopic measurement method, W and the number after it are used to indicate the particle size number, and the value after W represents the actual size of the micro powder. For example, W20 means the actual size of the micro powder is 20 μm.
