Innovation in Deep Hole Drilling Technology

Jingzuan continues to push the boundaries of deep hole drilling technology with new processes that achieve unprecedented precision and efficiency.

Technical Achievements

Our engineering team has developed proprietary techniques that enable:

• Drilling depth-to-diameter ratios exceeding 100:1
• Surface finishes as fine as Ra 0.2μm
• Straightness tolerance of 0.02mm per meter
• Processing of exotic alloys including titanium and Inconel

These innovations allow us to take on projects that were previously considered impossible, opening new possibilities for our customers in aerospace and defense applications.
