Grinding Wheel
What is a grinding wheel?
Grinding wheel is also called bonded abrasive. Grinding wheel is a bonded abrasive with a certain strength that is formed by bonding ordinary abrasive into a certain shape (mostly round with a through hole in the center). It is generally composed of abrasive, bonding agent and pores, which are often called the three elements of bonded abrasive. According to the different classifications of bonding agents, the common ones are ceramic (bond) grinding wheel, resin (bond) grinding wheel and rubber (bond) grinding wheel.
Grinding wheel is the most widely used abrasive tool. It rotates at high speed when used, and can be used for rough grinding, semi-finishing grinding and fine grinding of the outer circle, inner circle, plane and various profiles of metal or non-metal workpieces, as well as slotting and cutting.
Working principle of grinding wheel
The grinding wheel can perform rough grinding, semi-finishing grinding, and fine grinding, as well as grooving and cutting on the outer circle, inner circle, plane and various surfaces of metal or non-metal workpieces by rotating at high speed.
Factors affecting grinding wheel
Abrasive: The main component of the grinding wheel. Commonly used abrasives include oxides and carbides.
Grain size: Indicates the size of the abrasive particles. The larger the particle size, the coarser the abrasive particles.
Hardness: The hardness of the grinding wheel determines its grinding ability. High-quality grinding wheels should have high hardness and good sharpness.
Binder: Affects the strength and toughness of the grinding wheel. Different binders are suitable for different grinding tasks.
Shape and size: The shape and size of the grinding wheel will affect its scope of application and grinding effect.
These characteristics together determine the performance and applicability of the grinding wheel under different grinding conditions.
Grinding wheel characteristics
1. Physical properties: The grinding wheel has high hardness, brittleness and microporous structure characteristics. It is mainly made of abrasive binders and other additives pressed under high temperature and high pressure. These physical properties enable the grinding wheel to effectively remove materials during the grinding process.
2. Chemical stability: The grinding wheel will come into contact with various materials during the grinding process, so it must have good chemical stability and is not easy to react chemically with the processed materials. This ensures the durability and service life of the grinding wheel.
3. Process performance: The process performance of the grinding wheel is mainly reflected in the grinding efficiency, grinding force and grinding temperature. High-quality grinding wheels can achieve efficient material removal while maintaining low grinding force and temperature, improving processing accuracy and surface quality.
4. High-speed operation: The grinding wheel has high resistance to centrifugal force and thermal shock, and can remain stable when rotating at high speed, ensuring the smooth progress of the grinding process. This is crucial to improving grinding efficiency and processing quality.
In summary, the characteristics of the grinding wheel include its physical properties, chemical stability, process performance and high-speed operation. These characteristics make grinding wheels widely used in metal processing, stone carving, ceramic processing and other fields, and play an important role in improving processing efficiency and product quality.
