Description

The newly designed PRO models of Knuth’s bestseller V-Turn convince with improved ergonomics and more safety. Equipped with an inverter and a high-performance spindle motor, they can easily reach 3,000 revolutions per minute. Workpieces with a small diameter can thus be efficiently machined. However, the models also offer strength and stability for heavier machining. The built-in function of the constant cutting speed, which adapts the spindle speed to the diameter when facing, enables turning results that are comparable to CNC machines to be achieved.

Features

  • Incl. 3-axis position indicator with integrated spindle speed display, fully assembled
  • The redesigned machine enclosure and added safety features make this machine even more ergonomic, complementing functionality and design
  • Constant cutting speed: during face turning, the spindle speed automatically adapts to the changing workpiece diameter – the constant cutting speed at the cutting edge of the turning tool ensures superior turning results with quality comparable to CNC lathes
  • A heavily ribbed machine bed, rigid headstock and a massive one-piece cast-iron stand form a solid machine base
  • Wide, induction-hardened guideways ensure superior turning results and long life
  • Facing and top slides feature adjustable guideways and spindle nuts
  • High-precision pre-loaded spindle bearings ensure superior concentricity and load capacity
  • A powerful 7.4 HP main spindle motor ensures rapid acceleration and powerful chip removal across the entire speed range
  • Back-gearing ensures high torque for highly efficient machining
  • Rugged feed switch at the support simplifies operation
  • The extensive features of the X.Pos Position Indicator are complemented here with a digital speed indicator and an easy to program auxiliary function
  • 3-axis position indicator
    • More accuracy
