Abrasives are tools used for grinding, lapping and polishing. Most of the abrasives are artificial abrasives made of abrasives and binders, and there are also natural abrasives that are directly processed from natural ore rocks. In addition to being widely used in machinery manufacturing and other metal processing industries, abrasive tools are also used in food processing, paper industry and processing of non-metallic materials such as ceramics, glass, stone, plastic, rubber, and wood.

Hard abrasives are used when processing soft materials, otherwise soft abrasives are used, but soft abrasives are also used when grinding extremely soft and tough materials.

The gloss of the veneer stone is an important criterion for evaluating the quality of the stone. The size of the gloss depends on the refractive index of the various minerals that make up the rock on the one hand, and is closely related to the microstructure of the stone surface on the other hand.

Terrazzo is a cement-shaped artificial stone with physical properties and characteristics such as high density, high hardness, wear resistance, no dust generation, and not easy to peel off. Ordinary terrazzo is generally rough in construction, and the bright surface depends on cleaning and surface waxing and polishing to obtain a better surface effect in a short time. Even so, the polished effect cannot be compared with the natural marble surface, but because of its unique characteristics, terrazzo is still widely used in modern enterprises, factories, courtyards, schools, office buildings, exhibition halls, squares and other places.

In the process of constructing the concrete sealing and curing agent floor, one of the important steps is polishing, which is mainly divided into preliminary polishing and comprehensive polishing. However, it should be noted that in order to make the concrete floor have a high gloss and a more beautiful appearance, the concrete sealing and curing agent floor polishing should be completed after the wear-resistant aggregate and the concrete penetration hardening agent technology are perfected.

Abrasive is a kind of granular material with high hardness and certain mechanical strength, which is used to manufacture abrasive tools or directly used for grinding and polishing. As a basic characteristic that an abrasive must have, generally speaking, it should meet the following five requirements.

Grinding characteristics of PCD materials (1) Great grinding force (2) The grinding ratio is very small (3) The particle size has a great influence

Cement floor polishing is the same as concrete floor polishing. Due to its excellent characteristics, more and more people are beginning to pay attention.

The pervious concrete floor is environmentally friendly, practical and beautiful, but it is not easy to construct, especially the preparation and maintenance during the construction process are very important, which is related to the quality and cost of the floor after construction.

Diamond tools have excellent adaptability in the processing of non-ferrous metals and wear-resistant materials.

Polishing is the process of processing the surface of ceramic products by using the high-speed rotation of various grinding heads of polishing machinery. The polishing process includes: scraping grinding, rough grinding, medium grinding, fine grinding, polishing, edging and chamfering.

How to judge the strengths and weaknesses of diamonds, every practitioner should know professional knowledge. The following briefly discusses several important indicators for judging the strengths and weaknesses of diamonds.
