BTA Deep Hole Boring Machine
Note
- BTA deep hole boring machine is introduced 1 spindle design.
- The BTA machine is introduced single rotation of drilling spindle. The workpiece is fixed non-rotary.
- Capable drilling concentric, eccentric, indexable and slant hole.
- Bore hole diameter is from 80mm to 150mm.
- CNC control, convenient operation.
Clamping & Positioning
BTA deep hole boring machine’s clamping is by hydraulic chuck and steady rest. And can customize in term of the real situation of workpiece.
