Description
Sinus 400/3000 D is a conventional universal lathe built on a heavy one-piece cast bed. Designed for machining long shafts and large flanges, it combines classic mechanical drive elements with integrated functions — removable bed bridge, rapid traverses and a taper-turning device — to support flexible production workflows.

Highlights

• One-piece heavy cast bed for high rigidity
• Large spindle bore (105 mm) for long shafts and pipes
• Mechanical multi-plate clutch for controlled spindle start-up
• Rapid traverse on X and Z axes to reduce non-productive time
• Taper turning device included for external and internal tapers

Machine bed

• Heavy, single-piece cast base frame to minimise vibration
• Induction-hardened and ground guideways (›HB 400) for durable accuracy

Headstock and drive

• Designed for precision and smooth running under load
• Spindle bore 105 mm, spindle mount D1-8, spindle taper ø113 mm / 1:20
• Mechanical multi-disc clutch provides smooth acceleration of heavy workpieces

Support

• Support movable in rapid traverse longitudinally and transversely to cut auxiliary times
• Integrated overload protection for feed shaft and lead screw
• Lead screw covered to reduce wear from chips and contamination

Tailstock

• Tailstock quill with robust, easy-to-read scale
• Long quill stroke for demanding drilling and centring operations
• Side adjustment for turning conical shafts between centres

Equipment and accessories

• Centralised lubrication on the support for simplified maintenance
• Taper turning device and quick-change tool holder system included as standard
• Fixed and travelling steady rests supplied for long workpieces
• LED lighting, large rear splash guard, coolant system and operating tools included
