Conventional lathe Sinus 330/3000 D

horizontal2-axisuniversal

Overview
Sinus D is the largest series in the universal lathe segment. The design follows a conventional layout based on a heavy one-piece cast machine bed. Power transmission between motor and spindle is via a manual multi-plate clutch. Integrated functions such as a removable bed bridge, rapid traverse and a taper turning device provide flexible solutions for machining long workpieces and large flanges.

Highlights

• One-piece heavy-duty cast bed for high rigidity
• Robust headstock with large spindle bearings
• Rapid traverse on two axes for fast positioning
• Taper turning attachment included for cone machining
• Comprehensive safety features

Product details
Machine bed

• Heavy, generously dimensioned one-piece cast base frame to dampen vibrations
• Bed guideways induction hardened and ground for long-lasting accuracy (>HB 400)

Headstock and feed gear

• Design ensures high accuracy and smooth running at elevated cutting speeds
• Large spindle bore 105 mm for machining long shafts and pipes
• Mechanical multi-plate clutch for smooth spindle start-up with heavy workpieces

Support

• Support moves in longitudinal and transverse directions with rapid traverse to reduce non-productive times
• Integrated overload protection for feed screw and lead screw to prevent damage
• Lead screw covered to minimise wear from chips and contamination

Tailstock

• Tailstock quill fitted with robust, easy-to-read scale
• Long quill travel (235 mm) for demanding drilling and centring operations
• Tailstock adjustable laterally for machining conical shafts (±12.5 mm)

Equipment and accessories (standard / included)

• Central lubrication system on the support supplying all guideways
• Taper turning device included for producing long external and internal tapers with automatic longitudinal feed
• Quick change between cylindrical and taper turning without adjusting upper slide or tailstock
• Standard foot brake pedal
• Large rear splash guard to keep the working area clean
• Bright LED lighting integrated in the support cover
• Multifunction quick-change tool holder system with change cassette (standard)
• Fixed and travelling steady rest supplied as standard accessories for long workpieces
• Latest generation position indicators supplied as standard
• Coolant system and extensive operating tools included
