Multi-functionality includes deep-hole drilling
A drilling centre combines deephole drilling with five other operations: spiral drilling and tapping; face and form Milling and counter-boring and measuring to machine in one clamping.
The lack of the drive belts and the spindle integrated coolant coupling eliminate external vibrations, leading to higher hole quality, productivity, and tool life.
The special designed coolant couplings allow the combination of extreme spindle speeds with through the tool coolant pressures up to 3,000 lb/in2.
Automatic tool clamping systems are optional when automatic tool changers are required for the machine.
The gundrilling machines are custom build and utilize linear roller guideways and precision ballscrews.
They can be fitted to almost any drill depth, ranging from 125mm to over 4000mm.
Optional features include full CNC, multiple axis drilling, compound angle drilling, conventional machining, etc * About TBT - TBT is a world-wide manufacturer of standard and special gundrilling machines and gundrill tools.
