Conventional lathe Sinus 330/2000 D

horizontaluniversalD1-8

Description
Sinus D is the largest series in the universal lathes segment. It is built on a heavy one-piece cast bed and uses a manual multi-plate clutch between motor and spindle. Integrated features such as a removable bed bridge, rapid traverse and a taper-turning device make the series suitable for long workpieces and large flanges.

Highlights

• One-piece heavy-duty cast bed for increased rigidity
• Sturdy headstock with large spindle bearings and 105 mm spindle bore
• Rapid traverse on two axes for fast positioning
• Taper turning attachment for internal and external tapers
• Comprehensive safety and overload protections

Machine bed

• Maximum stability: heavy one-piece cast base to suppress vibrations
• Long-lasting accuracy: bed guideways induction-hardened and ground (≥ HB 400)

Headstock and feed gear

• Construction ensures high accuracy and smooth running under heavy cuts
• Large spindle bore (105 mm) for shafts and pipes
• Mechanical multi-plate clutch for controlled spindle start-up

Support

• Movable steady rest in longitudinal and transverse rapid traverse to reduce non-productive time
• Integrated overload protection for feed screw and lead screw
• Lead screw covered to minimise chip and dirt ingress

Tailstock

• Robust, easy-to-read quill scale
• Long quill stroke for drilling and centering operations
• Lateral adjustment for machining tapered shafts between centers

Equipment and accessories (standard / included)

• Central lubrication system on the support for all guideways
• Taper turning device (standard) for long/slim tapers with automatic longitudinal feed
