Case1：medical hip implant ／ cutting and polishing
・The customer supplied us cobalt-chromium alloy bar material.
・Required machining accuracy:
Sphericity＜0.5μm, Surface roughness＜Ra0.03μm
・Our manufacturing process:
NC lathe cutting → spherical surface polishing → mirror polishing finish → inspection
→shipping.
Case2：medical hip implant ／ only polishing
・The customer supplied us blanking material of cobalt-chromium alloy.
・Required machining accuracy:
Sphericity＜0.5μm, Surface roughness＜Ra0.03μm
・Our manufacturing process:
spherical surface polishing → mirror polishing finish → inspection → shipping
Case3：thermal spraying
The customer wanted to use the product in a high temperature pipeline.
In this case, we can spray the surface of the spheres with a special alloy, which is a thermal spraying process.
Thermal spraying has a significant effect on product durability and wear resistance.
Case4：only processing OK
The customer can provide the materials and it is available that we only do the machining.
We have also manufactured many other types of balls and spheres. We manufacture steel balls not only for industrial fields but also for other various industries.
