KNUTH SINUS 330/3000 D MANUAL LATHES

Technical Description

The KNUTH SINUS 330/3000 D is a precision horizontal engine lathe engineered for heavy-duty turning operations with exceptional rigidity and accuracy. Built on a solid one-piece cast machine bed, this machine delivers maximum turning diameters of 660 mm (26 inches) over the bed and accommodates workpieces up to 3000 mm (118 inches) in length, making it ideal for long-shaft machining applications. The machine features a powerful 7.5 kW (10 HP) main drive motor operating at speeds up to 1,600 RPM with a spindle bore of 105 mm and D1-8 spindle mount. The X-axis provides 368 mm of travel with rapid feed rates of 2000 mm/min, while the Z-axis offers 230 mm travel with rapid traversal speeds reaching 4000 mm/min, ensuring efficient chip removal and reduced cycle times. A removable bridge measuring 320 mm extends the turning diameter capability to 900 mm for large-diameter workpieces, demonstrating remarkable versatility. The precision tailstock features a 5 MT taper with 235 mm quill stroke and ± 12.5 mm traverse adjustment for accurate workholding and center support. Threading capabilities span metric (0.45-120 mm), diametric (0.88-160 DP), and module specifications, accommodating diverse fastening requirements. The machine's overall dimensions are 4.71 m × 1.23 m × 1.6 m with a substantial weight of 3,300 kg, providing the mass necessary for vibration damping and precision work. This configuration enables simultaneous multi-tool operations with exceptional surface finish and dimensional accuracy across demanding production environments.
