Introduction to through-hole grinding wheel

A through-hole grinding wheel is a circular bonded grinding tool with a central through-hole formed by bonding the abrasive with a binder. The following is a detailed introduction to through-hole grinding wheels:
1, Basic composition
A through-hole grinding wheel is generally composed of abrasive, binder, and air holes. Abrasive is responsible for cutting, binder is used to fix abrasive particles, and pores help to remove chips and dissipate heat.
2, Types and shapes
There are various types of through-hole grinding wheels, which can be divided into ordinary abrasive (such as corundum and silicon carbide) grinding wheels and natural abrasive superhard abrasive (such as diamond and cubic boron nitride) grinding wheels according to abrasives; According to their shape, they can be divided into flat grinding wheels, beveled grinding wheels, cylindrical grinding wheels, cup-shaped grinding wheels, etc. Their common feature is that they all have a central through-hole, which facilitates installation on the grinder for high-speed rotation.
3, Purpose:
Through hole grinding wheel has a wide range of applications in grinding processing, which can perform rough grinding, semi precision grinding, and precision grinding on the outer and inner circles, flat surfaces, and various profiles of metal or non-metal workpieces, as well as operations such as slotting and cutting.
4, Specifications and Selection
The specifications of through-hole grinding wheels are usually determined by three dimensions: outer diameter, thickness, and aperture. When choosing, it is necessary to comprehensively consider the processing requirements, grinder model, and characteristics of the grinding material. In addition, attention should be paid to the abrasive type, particle size, hardness and other parameters of the grinding wheel to ensure processing quality and efficiency.
5, Manufacturing process
The manufacturing process of through-hole grinding wheels includes stages such as mixing, forming, sintering, finishing, and inspection. Among them, mixing refers to stirring abrasives, binders, and chemical raw materials; Forming is the process of compression molding the mixed raw materials into a grinding wheel mold; Sintering is the process of placing the formed grinding wheel into a kiln for high-temperature sintering; Refinement is the process of adjusting the sintered grinding wheel to achieve the correct dimensional accuracy and shape; Inspection involves conducting various performance tests on the grinding wheel to ensure its quality.
In summary, through-hole grinding wheels, as important tools in grinding processes, have broad application prospects and significant economic value.
