Knuth 7.4HP V-Turn 410 PRO Universal Lathe 300822

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 X.Pos 3.2

• Integrating multiple functions, this new generation of 3 axis digital readouts significantly offer a much better control over the machining processes, greatly decreasing down-times and error rates
• It features a totally sealed enclosure made of high quality polyester film which protects it against hazardous enviroments in shop floors, such as dust or fumes and offers excellent chemical resistance to most commonly used industry solvents
