OverviewThe V-Turn 410/1000 is a precision lathe designed for both accurate workshop turning and small-series production. Fitted with an inverter and a high-performance spindle motor, it provides two continuously variable speed ranges up to 3,000 1/min and delivers stable performance for heavier machining operations. The X-Pos integrated "constant cutting speed" function automatically adjusts spindle speed during facing to maintain cutting-edge speed and surface quality comparable to CNC lathes.
Highlights- Constant cutting speed (X-Pos)
- High spindle speed and 5.5 kW motor power
- Comprehensive standard equipment
- Large roller bearings from NSK
