Machine concept

Double Disc Face Grinding Machine

By ensuring flat and parallel surfaces, the DG grinding machines enhances the accuracy of subsequent machining operations. Perfect for production line integrations, these machines serves small or large production lots equally well.

Chucking and loading principles

The work piece is placed via an external robot between three rollers and is driven to rotate by two of them. A loading slide is feeding the work piece into the grinding position. For some work piece types the machine doesn´t require any manual change-over for different work piece dimensions. It is all done automatically.

Grinding Spindles

The two grinding spindles are belt driven by motors from 7,5 kW to 33 kW, with fixed or variable speed and selectable direction of rotation. Coolant supply through the spindles ensures efficient cooling.

Grinding Slides

The two linear roller bearing slides are run by belt driven servo motors and ball screws. 


Dressing units are mounted directly on the box frames. The DG300/400/800 are equipped with multipoint diamond dressers and the DG500/600/700 are equipped with driven diamond roller dressers.

Control system

Graphical user interface provides user-friendly controls and integrated program generator, IPG. The control system is Siemens 840D sl (Solution Line).

The SINUMERIK 840D solution line is a distributed, scalable, open and inter-connecting control system that offers a wide range of functions. This flexible, universal CNC can be used for up to 31 axes.
