Functions and Specifications
(1) Traceability of raw materials.
(2) Stabilized heat treatment technology.
(3) High precision (good roundness/roughness/hardness).

1. Title:
The first step is for the tunneling machine to cut the wire into short lengths and form a sphere between the molds.
2. Flickering:
A process for roughening a spherical blank and removing excess material around the sphere.
3. Heat treatment:
The ball is hardened by subjecting the alloy metal to controlled heating and cooling to improve its hardness and other properties.
4. Difficult trials and tribulations:
Slow and meticulous grinding ensures proper dimensions and size;
5. Grinding:
This process involves two steps: first, simple grinding, and then fine grinding. Both steps are to achieve a shiny finish and the precise dimensions required by ISO 3290 standards.
6. Cleaning:
First, clean the surface of the ball; then dry the ball with dehydrating oil; the final step is to apply rust-preventive oil to the ball. Once these steps are complete, each ball will be selected by machine or visually to ensure that each ball is perfect.
7. Inspection:
Each batch of products will be measured and inspected by a special inspector to check whether the products meet the customer's requirements.
