Our Deep Hole Processes

Advanced techniques for maximum precision, efficiency, and surface quality.

Gun Drilling

Ideal for small diameter deep holes (0.5–50mm), gun drilling uses a single-lip tool with internal coolant supply to achieve high depth-to-diameter ratios and excellent straightness.

L/D up to 300:1
Tight tolerances (±0.02mm)
Smooth surface finish

BTA Drilling

For larger diameters (≥18mm), BTA (Boring and Trepanning Association) drilling offers high material removal rates and superior chip control using external coolant and internal chip evacuation.

High productivity
Excellent chip removal
Ideal for mass production

Honing

Final finishing process that improves geometric form, surface texture, and dimensional accuracy of bores using abrasive stones under controlled pressure.

Ra < 0.2 µm surface finish
Cross-hatch pattern for oil retention
Used in hydraulic cylinders and engine blocks

Milling Center Integration

Combine deep hole drilling with multi-axis milling for complete part processing in a single setup, reducing cycle time and improving accuracy.

Reduced handling
Improved repeatability
Complex geometries supported
