GMSi Group Inc. offers the Dowell VHR-500/600 high-precision, multiple-function grinding machine with a vertical and horizontal spindle. The vertical Y-axis spindle uses a pneumatic counterweight to reduce ballscrew and servomotor loading and make movement smoother and extend machine life. The horizontal spindle uses six ball bearings for heavy grinding.

The Y-axis has a Class 1 50mm-dia. (1.97") ballscrew to provide stability during feeding. Rigid linear roller guides enable smooth vertical and longitudinal feeding while maintaining a high level of stiffness. The grinder's Meehanite Class FC30 casting with slide way provides stiffness and wear resistance. Standard accessories include a flange/grinding arbor, an automatic paper strip filter with magnetic separator and coolant system, an oil mist collector, an inverter and an air conditioner.
