VOLLMER VGRIND 340S

VOLLMER VGRIND 340S – SUPERIOR IN EVERY WAYTHE GREATEST PRECISION FOR EVEN THE SMALLEST OF TOOLS

Vertical multi-level machining that sets new standards. The precision and efficiency of the VGrind series is now also available for rotationally symmetric solid carbide tools in the 0.3 mm to 12.7 mm range. The VGrind 340S: A five-axis grinding machine that is equipped with all the attributes that modern tool manufacturing requires. And, what's more, there are plenty of intuitive details for the production of small sizes to boot. New linear induction motors on the x, y and z axes provide a clear increase in performance. The result: Even greater precision, for an even better surface quality.

THE APPLICATION

The VGrind 340S was designed to produce carbide drills and milling cutters with a diameter ranging from 0.3 to 12.7 mm. The high flexibility provided by the possibility to change both grinding wheel packages, the reduced changing times thanks to the positively guided system and the meaningful automation options provide the best prerequisites for efficient and high-quality manufacturing.

THE MACHINE CONCEPT

Precision and efficiency squared: This principle is also followed by the VGrind 340S – thanks to two vertically arranged grinding spindles. This principle is complemented by several useful details and options for machining small radii. The result: Maximum perfection at the lowest tolerances.

• Five-axis CNC grinding machine with innovative kinematics
• Two grinding spindles situated one above the other with the grinding wheel set positioned at the C axis pivot point – for ensuring extremely precise grinding results
• The vertical spindle arrangement solves the well-known problems related to fixed and floating bearings
• New wear-free linear induction motors on the X, Y and Z axes not only guarantee lasting consistency of quality and lower maintenance costs, but are also the key to improved surface quality
• Innovative wall concept with the highest possible rigidity and outstanding damping thanks to polymer concrete
• Equipped with a tool steady rest as standard for the best radial run-out quality on the tool, as well as linear scales for even greater precision
• Effective motor and spindle cooling concept for higher thermal stability and lasting power and precision
• Both spindles can be fitted with various different grinding wheel sets. The automation option ensures seamless conversion
