CNC BTA Drill Machine
- BTA drill machine is introduced 1 spindle design.
- The model is suitable to drill hole diameter from 40mm to 100mm.
- Single rotation of drilling spindle and workpiece is fixed to be non-rotary.
- Dual-chuck clamping to stable and keep rotary precision of workpiece.
- The machine is designed to fit for processing of workpiece with long length and big diameter like hydraulic cylinder, etc.
Clamping & Positioning
BTA drill machine clamping is by hydraulic chuck and self-centering chuck (manually) as standard deisgnation. For some special workpiece, the clamping method can be adjusted to ensure the best stability and precision.
