Not on every machine – you need the right one!
We have to be extremely careful with this type of machining. The load on the A axis and the spindle is extremely high. A machine that is not prepared for this sort of cutting may be damaged in the process. In our case, the best machine to make this kind of machining in titanium is the Makino T2.

The moving column structure and the ultra-heavy-load type table give this machine the rigidity needed for cutting torques of over 1,000 Nm. The spindle, which has a continuous rating of 1,000 Nm, can generate up to 1,500 Nm if required by the parts. This is especially useful when machining the hard spots appearing on titanium forgings and the increasing radius of old forging dies.
The active dampening system and the semi-floating system gives the machine the ability to damp the vibrations the system generates.
Last but not least, 70 bar, 200 litres/minute is the minimum flow needed when using long porcupines so as to feed coolant to all the cutting edges of the tool.
