Metal lathe, Knuth Sinus 330/2000 D

Metal lathe, Knuth Sinus 330/2000 D

Manufacturer: Knuth, Germany

Sinus D is the largest series of machines in the segment of universal machines. The construction of the machine is based on the classic design, but built on a heavy, cast base. As a high-power metal lathe, it uses a manual multi-disc clutch that connects the motor and the drive shaft. Incorporating features such as removable bridge, quick transitions and taper lathes, this series offers additional solutions for machining long products or large flanges.

• One - piece heavy casted bed for increased rigidity.
• Sturdy headstock design with minimum vibrations.
• Rapid feed on 2 axes ensure fast positioning.
• Taper turning attachment for additional applications.
• Well thought out safety protection.

More detailed description:

• Removable bridge (250 mm) to allow machining of large parts up to 1035 mm in diameter.
• High precision and silent operations, even with high cutting power.
• Heavy and large bed.
