The VTC 800/30HD is a 50-taper variant for hard-to-machine materials, such as Inconel and titanium that can cause spindle vibration, the company said.

The variant has a highly rigid column and carrier structure so it can deliver its power with no vibration or loss of accuracy.

Mazak said its 10,000-rpm spindle delivers continuous power of 22kW and a short-time torque of 302Nm. In production, the machine delivers a rapid feed rate of 50m/min in the X, Y and Z axes; 0.5G of acceleration and a 5.7-sec chip-to-chip time. Thirty-six tools are provided as standard.
