New Viking SuperSeries II Centerless Grinder is Optimized for Precision Production Processes

Powerful, user-friendly control and highly reliable spindle are key features of new grinder model.

Chicago, Ill., Sept. 8, 2004 -- Landis Grinding Systems is introducing, in booth A-8101 at IMTS 2004, a newly enhanced version of the compact and productive Landis Cincinnati Viking CNC Centerless Grinder. The new Viking SuperSeries II centerless grinder has a combination of advanced technology and user-driven features that makes it ideal for high production applications and for grinding a diverse range of materials and components to precise tolerances using either conventional or superabrasive wheels.

The new Viking SuperSeries II centerless grinder incorporates the Landis 6400 CNC, a powerful and versatile PC-based, open-architecture control system that is hardware-independent and frees the end user from expensive and difficult to maintain proprietary hardware. The control's easy-to-use interface is intuitive for operators accustomed to manual grinders, while the readily accessible RS-274 standard "G-code" programming accommodates experienced programmers and more complicated grinding processes.

Landis has also incorporated several new features and components that further improve the reliability and maintainability of the Viking centerless grinder. These include digital servo controls which provide higher torque capability; a SERCOS interface that significantly reduces wiring; a new sealing arrangement for the grinder's anti-friction spindles to prevent ingress of contaminants; an improved stub shaft design that facilitates easier grinding wheel spindle replacement; control cabinet air conditioning as standard for improved reliability; and a standard remote operator hand wheel to permit faster set-ups.

Other key features of the Viking SuperSeries II centerless grinder include a nodular cast iron base for strength, stability and vibration damping. Both wheels utilize Twin-Grip mounting to eliminate orbiting and resist wheel-separating pressures under heavy loads. Even with a Twin- Grip arrangement the design allows for a 15-minute spindle-to-spindle change. The Viking grinder delivers consistent accuracy through a combination of sub-micron control resolution, a 2-1/2 inch diameter ballscrew, dual-axis upper/lower slide arrangement, linear scale feedback, A.C. brushless servomotors, and CNC profile contouring on both wheels.

The Viking centerless grinder accommodates parts from 0.05 to 2.4 inch diameter. The machine has a 20 hp or optional 40 hp grinding wheel drive. Surface speeds range from 8,500 sfpm to 12,000 sfpm for conventional abrasives and up to 16,000 sfpm for superabrasive applications. A 16 inch diameter grinding wheel is standard, with an optional 18 inch wheel available providing up to 10 inch of wheel width. Regulating wheel diameter is 12 inch standard, with a 14 inch diameter wheel optionally available. The all-electric Viking grinder is engineered for fast job changeovers. It has excellent ergonomic functionality and includes advanced mist and coolant containment.

Landis engineers say that the Viking delivers a unique combination of value, precision, productivity and practical usability that sets it apart from other centerless grinders. The Viking is rigid enough to process even hard metals and ceramics to sub-micron accuracy, yet robust enough to thrive in a production environment.
