White Corundum Cup-shaped Grinding Wheels

White corundum grinding wheels can be categorized by their shape, including flat wheels, beveled wheels, cylindrical wheels, cup wheels, dish wheels, bowl wheels, concave wheels, and tapered wheels. They can also be classified by the type of binder, such as ceramic wheels, resin wheels, rubber wheels, and metal wheels. The main characteristics of grinding wheels include abrasive, grit size, hardness, binder, shape, size, and more.

Product Description

The white corundum cup-shaped grinding wheel, also known as cup grinding wheel, is mainly made from white corundum abrasive combined with a proportionally mixed binder, processed through pressing and sintering, and subjected to a series of production processes from inspection to the finished product. This white corundum grinding wheel is mainly used for the grinding, grooving, deburring, and polishing of cutting tools. It can be used on stainless steel, high-speed steel, 45# steel, quenched steel, cold castings, and more.

Since grinding wheels typically operate at high speeds, it is necessary to conduct a rotation test (to ensure the wheel won't break at the highest operating speed) and a static balance test (to prevent machine tool vibration) before use. After a period of use, grinding wheels should be dressed to restore their grinding performance and correct geometry.

1. When selecting the hardness of grinding wheels, it should be based on the material being ground. For grinding hard materials, a harder wheel should be chosen, while for grinding soft and ductile non-ferrous metals, a softer wheel is preferred.

2. The choice of grit size for grinding wheels is essential. Coarse grit wheels offer higher productivity but result in rougher workpiece surfaces. Fine grit wheels produce smoother workpiece surfaces but with lower productivity. It is advisable to use coarse grit wheels as long as the required surface roughness is met, and coarse wheels are typically used for rough grinding, while fine grit wheels are used for precision grinding.

Grinding wheels need to be dressed after a period of use, and it is recommended to use a dressing stick or a diamond grinding wheel to achieve a smooth and even surface.
