Yamazaki Mazak Heavy-duty version of VTC has been designed for hard-to-machine materials
And is said to deliver higher levels of spindle torque and power demanded by 50 taper performance in aerospace, marine, heavy equipment and power generation.
Yamazaki Mazak has developed a heavy-duty version of its UK-built VTC 800 series of vertical travelling column machining centres.
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.
