Process of Making Ball Bearings. A Mechanical Parts Manufacturing Factory in Korea.

Summary

YH System, based in Gimpo, Korea, specializes in the production of precise mechanical parts, including ball bearings. The process starts with raw iron material, which undergoes a series of steps: sawing, heating, heat forging, and detailed inspections. Advanced techniques like fine cutting, 3D measuring, and heat treatment ensure precision. The ball bearings are then plated, laser-marked, and finely ground before being assembled, injected with grease, and sealed. The entire process is focused on achieving high-quality, durable bearings for various applications.

Takeaways

• 😀 The ball bearing production starts with selecting iron as the raw material.
• 😀 The first step in manufacturing involves cutting the raw iron material into the required size using a sawing process.
• 😀 The material is then heated to prepare it for shaping and further processing.
• 😀 Heat forging is used to shape the material under high pressure and temperature, improving its structure.
• 😀 After the forging process, the material undergoes a thorough inspection to check its quality before moving forward.
• 😀 A fine cutting process is employed to achieve precise shaping of the components.
• 😀 The use of a 3D measuring machine ensures accuracy and precision in the material's dimensions.
• 😀 The bearing material undergoes a hardening heat treatment to enhance its strength and durability.
• 😀 After hardening, another inspection is conducted to ensure the material has undergone the heat treatment process correctly.
• 😀 The bearings undergo a plating process, which may involve coating for corrosion resistance or other properties.
• 😀 Laser marking is applied to the bearings for identification, branding, and serialization purposes.
• 😀 A fine grinding process is used to smooth the components and achieve the required level of precision.
• 😀 The individual bearing parts are assembled carefully to form the final product.
• 😀 A grease injection process is used to fill the bearings, reducing friction and enhancing smooth performance.
• 😀 The bearings are sealed to protect the internal components and grease from contamination.
