The machine adopts double spindle structure, gun drill and BTA share a set of spindle, which is suitable for processing coaxial holes on shaft parts; When converting gun drill and BTA, it is
necessary to manually change tools, auxiliary tools and switch oil circuit to realize the conversion of the two processing methods.
When machining, the tool and the workpiece rotate relatively,or the workpiece is fixed, the tool rotates and feeds.
Working capacity:
Drilling mode: Gun drilling mode (external chip removal) and BTA mode (internal chip removal)
Gun drill drilling range: φ 6- φ 25mm
BTA drilling range: φ 25- φ 60mm
Max machining depth: 1500mm
Max workpiece OD: Φ 170mm
(For big OD workpiece(More than 170 mm) , you can use single spindle drilling with fixture. Under this mode , the workpiece is fixed)
