Heavy duty machining
High torque, 50 taper machines have been increasingly in demand as the sector searches for machines which can combine power with accuracy. Mazak’s VTC-800/30HD, which stands for ‘heavy duty’, is a 50 taper variant of the highly successful VTC-800 series of machines. The HD version provides an ideal platform for cutting hard-to-machine materials, combining a machine structure that has been optimized for stability, with a high rigidity integral design spindle to deliver class leading machining capability.
In order to deliver outstanding metal removal rates and counteract the potential for vibration, the VTC- 800/30HD incorporates a new highly rigid column, carrier and base structure designed to enable the machine to deliver all of its power with no vibration or loss of accuracy. The high performance machine structure has been designed to provide class-leading static and dynamic stiffness, enabling the HD to deliver the higher levels of spindle torque and power demanded by 50 taper performance.
The Mazak designed and manufactured 10,000rpm spindle delivers continuous power of 22kW and a short time torque of 302Nm. In production, the machine combines agility with power and will deliver a rapid feed rate of 50m/min in the X-,Y- and Z-axes; 0.5G of acceleration and a 5.7 second chip-to-chip time. 36 tools are provided as standard.
