THE ULTIMATE TURNING MACHINES

V550

13-3/4″x25-1/4″ Variable-speed Lathes

Compact, powerful high speed lathe with precision capability.

The V350’s cast iron base provides maximum support for the torsionally stiffened bed and prevents swarf accumulation. The bed is epoxy resin bonded to the base and provides excellent structural damping and resistance to vibration. The universal gearbox adds to the machines overall ability to handle the small to mid-range turning requirements of many toolrooms, production workshops and educational establishments
