The classification of abrasive equipment in the stone industry is quite complex. It can be divided into two categories based on the source of the raw materials: natural abrasives and synthetic abrasives. In the mechanical industry, the commonly used natural abrasive is oil stone. Synthetic abrasives can be further categorized based on their basic shape and structural characteristics, including grinding wheels, grinding heads, oil stones, sand tiles (collectively known as bonded abrasives), and coated abrasives. Additionally, abrasive grains are also considered a separate category of abrasives.
Bonded abrasives, also known as conventional abrasive tools, are formed by binding ordinary abrasives into specific shapes with a certain strength. They typically consist of abrasive grains, bonding agents, and pores, which are commonly referred to as the three essential components of bonded abrasives.
Based on the types of abrasive grains used, bonded abrasives can be classified into two categories: conventional abrasive bonded abrasives and super hard abrasive bonded abrasives. The former is made of ordinary abrasives such as corundum and silicon carbide, while the latter is made of super hard abrasives like diamond and cubic boron nitride.
In general, the key characteristics of conventional abrasive bonded abrasives include shape, size of abrasive grains, particle size distribution, hardness, structure, and bonding agents. There are several methods commonly used to measure the hardness of abrasive tools, including the hand cone method, mechanical cone method, Rockwell hardness testing method, and sandblasting hardness testing method.
