BTA Deep Hole Boring Machine ZK21150D/2000

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.
