ENGINE LATHE

Sinus 400/3000 D

Machine bed

• Maximum stability: The machine is based on a heavy, generously dimensioned bed on a solid, one-piece cast base frame, which effectively eliminates vibrations
• Long-lasting accuracy: For lasting precision and low wear, the bed guideways are induction hardened and ground (>HB 400)

Headstock and feed gear

• Precision under load: The design guarantees high accuracy and exceptionally smooth running, even at high cutting speeds
• Large passage: With a spindle bore of 105 mm, the machine is ideally suited for machining long shafts and pipes
• Proven drive: A mechanical multi-plate clutch ensures smooth spindle start-up – ideal for accelerating heavy workpieces

Support

• Reduced non-productive times: To increase productivity, the support can be moved in both the longitudinal and transverse directions in rapid traverse
• High operator protection: Integrated overload protection for the feed screw and lead screw prevents damage due to incorrect operation or collisions
• Protected design: The lead screw is covered to minimise wear caused by chips and dirt

Tailstock

• The tailstock quill is equipped with a robust and easy to read scale
• The long quill stroke allows for complex drilling and centering jobs
• The tailstock can be adjusted laterally for machining of conical shafts

Equipment and accessories

• The central lubrication system on the support supplies all guideways with lubricant and simplifies machine maintenance
• A taper turning device is included as standard and enables the production of long, slim external and internal tapers in a single pass with automatic longitudinal feed
• Since neither the upper slide nor the tailstock need to be adjusted, quick changing between cylindrical and taper turning is a major advantage
• The standard foot brake pedal is not only practical, but also a safety feature
• The large and stable splash guard at the rear of the machine ensures a clean machine environment
• Bright LED lighting is integrated into the support cover and illuminates the working area optimally
• The multifunctional quick-change tool holder system with a change cassette is standard equipment in this series
• A fixed and a travelling steady rest are also standard accessories, indispensable for long workpieces
• The series is equipped with the latest generation of our position indicators as standard. Higher working accuracy, a lower error rate and increased production reliability pay off
• A coolant system and extensive operating tools complete the equipment package
