Bearings are used to reduce friction between two moving parts. Metal type is important for bearing performance.

• Metal type affects bearing strength, durability, and resistance to corrosion.

• Common bearing metals include steel, bronze, and ceramic.

• Steel bearings are strong and durable, but can corrode in certain environments.

• Bronze bearings are self-lubricating and resistant to corrosion, but not as strong as steel.

• C...read more

Grinding process involves removing material from a workpiece using an abrasive wheel or belt.

• Grinding is a finishing process used to improve surface finish, accuracy, and dimensional tolerances.

• The principle of grinding involves the use of an abrasive material to remove material from the workpiece.

• The grinding wheel or belt rotates at high speed, while the workpiece is held stationary or fed into the rotating whee...read more

The rejection and rework percentage in the current industry varies depending on the sector and the quality control measures implemented.

• The rejection and rework percentage can be affected by factors such as the type of product, the manufacturing process, and the quality control measures in place.

• In the automotive industry, the rejection and rework percentage can be as low as 1% for some manufacturers, while others...read more
