We have been manufacturing rock drill parts for over
20 years.
1) Mechanical Analysis
We are an R&D Business Partner with our government's
technology institute. They help us to analyze mechanical
properties, heat treatment techniques used in the genuine
parts.
2) Heat Treatment
After analysis of the case depth and hardness and core
hardness of genuine parts, we reproduce almost the same
parts as the OEM with our advanced metal heat treating
technology.
3) Engineering Design
We pay extra attention to the tolerances of each part.
To control tolerances, we do a thorough inspection 100%.
