A new series of internal and external grinders for high volume manufacturing of bearings and similar parts. The machine concept is based on the earlier generations of Lidkoping machines delivered in thousands all over the world. While this concept originally was made for the small range bearing sizes, the all new High Volume™ machines take this well proven concept also into the medium and large segment of bearings and other work pieces.

The direct driven grinding wheel spindle carries a O 610 mm grinding wheel, up to 120 mm wide, with or without automatic balancing built-in to the grinding wheel flange. With the grinding wheel dresser fixed onto the machine base, during the grinding cycle, the grinding wheel spindle is moving between three positions; grinding, loading and dressing.
