1.Abrasive: A material that acts as a cutting tool in grinding, grinding, and polishing.
2.Abrasive grain: Abrasive material is artificially made into a specific particle size, used to make the grinding material of the remaining material, grinding and polishing the particle material of the tool.
3.Particle size: measure and diameter of the abrasive grain size
4.Micropowder: Ordinary abrasives that are not coarser than 240 grit, abrasive or fine abrasive abrasives finer than 36/54μm
5.Coarse abrasive grain: diameter of the abrasive particles of 4-220 grit number. Abrasive No. 12 or above must be processed in a special process and must be customized in advance.
6.Granular number: graded mark on the size of the abrasive grain according to the implementation criteria
7.Single crystal: crystal atoms are arranged in a very regular pattern with regular shape and anisotropy
8.Polycrystalline: a crystal shape consisting of many small grains that tend to be different
9.Magnetic substance: a general term for the magnetic properties of magnetically sensitive substances in abrasive grains.
10.Repose angle: the abrasive sample falls from a certain height through a funnel on a horizontal metal plate, and the angle between the tapered surface and the bottom surface of the cone formed is generally calculated from the diameter and height of the cone.
11.Bulk density: the mass of abrasive grains per unit volume of air in the case of natural accumulation, in grams per cubic centimeter
12.Natural abrasive: abrasive that is directly extracted from natural ore, sorted, crushed, graded or otherwise processed.
13.Capillary phenomenon: the abrasive particles are placed in a glass tube of a certain diameter, and the lower end is immersed in water, and the height of the water rises in a given time (mm)
14.Artificial abrasive: An abrasive that is refined or synthesized by an artificial method. The abrasive of Abrasives Industry Co., Ltd. is an artificial abrasive.
15.Specific surface area: The total surface area of a unit mass of abrasive, in meters per gram
16.Impact toughness: impact resistance and fracture properties of abrasives
17.Compressive strength: the load value of a single abrasive grain under static pressure, broken, unit Ñ
18.Free abrasive grain: abrasive grain directly ground or polished in a free state
19.Particle size composition: a combination of graded marks made by a nominal grain size
20.Mixed particle size: abrasive grain size obtained by mixing two or more sizes of abrasive grains in a set ratio
