Capabilities

The Unitech UT 660x4000 is a versatile CNC cycle lathe designed for precision turning and cylindrical machining. With a 4000mm distance between centers and maximum swing diameter of 960mm over the bed bridge, it handles both small detailed components and larger shafts. The 15kW spindle delivers 1600Nm of torque at up to 2000rpm, while the 8-position VDI 40 tool changer enables fast, automated production runs with minimal manual intervention.

Industries & Uses

This machine suits job shops, contract manufacturers, and production facilities working with metals—from automotive suppliers making engine components to industrial equipment manufacturers producing drive shafts and bearing housings. It's ideal for businesses moving beyond manual lathes who need consistent quality and faster throughput without the complexity of full transfer machines.

What to Check When Buying

When evaluating a used unit, request complete maintenance records and spindle bearing history—these are high-wear items. Inspect the bed and ways for wear patterns or scoring, check quill runout and chuck jaw condition, and verify the Siemens control system operates smoothly. Ask about coolant system maintenance and whether any major repairs or spindle rebuilds were performed. Request a test run if possible to assess noise levels and accuracy.
