Highlights
Knuth DL S Universal Heavy Duty Lathe Series
The DL S lathe series is slightly smaller than the DL E Heavy, but is also designed for large turning diameters and workpiece lengths. It is the solution for conventional machining of workpieces up to 5000 mm (197 in.) in length and over 720 mm (28 in.) in diameter. The particularly wide and heavily ribbed machine bed accommodates the heavy workpiece weights. The multi-disc clutch gives the operator control over the dynamics of the spindle start-up and the rapid traverse in the support is particularly effective with large bed lengths.
- Center widths up to 5000 mm (197 in.)
- Spindle bore of 100 mm (4 in.)
- Powerful motor
- Spindle speed can be adjusted in 4 steps
- Rapid feed in Y
- and Z-direction
- Complete with assembled 3-axis position indicator
