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.

Machine Concept

Slide system

Hydrostatic length slide, driven by servomotor and ball screw. Dovetail type cross-slide, manually operated.


Fast full profile diamond roller dresser for the highest productivity needs or NC-dresser for more flexibility.

Grinding spindles

A direct driven grinding spindle enabling grinding wheel peripheral surface speeds up to 60 m/s. As option the grinding wheel is automatically balanced.

Work head spindle

The work head spindles is direct driven and supported by high precision angular contact ball bearings. The work head can be swiveled -0.5 to 30 degrees.

Gauging method

In-process 1-finger electronic gauging head.

Machine control

Graphical user interface provides user-friendly controls. Control System, Siemens 840D sl.
As an option the machine can be equipped with Acoustic Emission analysis for process supervision and gap-elimination.

Chucking principle

Shoe centerless or centric.


The work pieces are loaded through in- and outlet chutes.

Grinding Operations

External grinding of  bearing rings, rollers or other applications.
