After cold heading, the ball embryo will form a ring belt, and the Flashing is polished off the ring belt in the grinder.

1. Process principle

The process principle of the photosphere is mainly based on the physical and chemical characteristics of the metal material, and the irregularity of the surface is removed by the grinding principle to achieve high precision and low roughness.

2. Optical ball equipment

Grinding machine: including circular grinding and internal and external circular grinding, for fine grinding, to ensure that the diameter, shape and surface finish of the light ball meet the standards.

Coordinate measuring machine: Used for high-precision size and shape inspection.

3. Flashing process flow

Grinding: Through the grinding process to achieve high precision size and roundness.

Quality inspection: The use of coordinate measuring machine and other equipment to carry out comprehensive quality inspection of the photosphere to ensure that the standard is met.

4. Advantages of Flashing process

The photosphere process can achieve precise control at the micron level to ensure that the diameter, roundness and shape of the sphere meet the process standards.

5. Shortcomings of Flashing process

Large equipment investment: high-precision processing equipment and testing instruments are required, and the investment is large.

High technical requirements: the process requires precise control, and the operator needs to have a high level of professional technology.

Sum up：

The manufacturing process of photosphere is a complex and specialized technology, involving the knowledge of many disciplines such as machining and surface treatment.
