Product Details

• Workpiece length (max.): 118”
• Workpiece weight (max.): 8,800 lbs.
• Turning diameter over bed: 33”
• Turning-Ø over support: 20”
• Description
• 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.
• Features
• Extra heavy, wide machine bed with heavy ribbing and mono-block construction
• Induction-hardened and ground guide slots ensure long-term accuracy and minimum wear
• Massive headstock with high-precision main spindle on a tapered roller bearing with 4 inch spindle bore for excellent stability under heavy loads
• Very quiet operation at maximum spindle speed
• Joystick control for X and Z feeds is mounted directly to support
• Manually shifted 4-step gearbox with high-quality frequency control combined with a powerful main spindle motor with up to 10 Hp power allow exact tuning of rpm and high torque to provide maximum power even under heaviest loads
• For quick positioning and reduced down-time, the support is equipped with a rapid feed on X- and Z-axes
• Adjustable overload clutch in apron protects the feed mechanics from damage and failure
• Central, practical controls for feeds and thread leads
• The auxiliary gearbox features a wide spectrum of diametric, inch, module, and metric threads
