The diamond parting-off grinder DS750 NC 4 is an innovative production machine

The workpiece can be processed on four axes with any interpolation. The wire is driven by a three-phase current motor controlled by a frequency transformer. The speed of the wire can be set at any point between 100 and 3000 m/min. Unlike the DS750 NC, the DS750 NC 4 machines workpieces in an upright position. The cut part does not fall downward. This allows several parts to be cut in succession without operator intervention. To insert and tension the wire, the drive motor and the drive roller are moved with a pneumatic cylinder. The wire tension is controlled by the adjustable air pressure on the pressure reducer.

The process of programming the workpiece contour with external CAD programs is supported by such features as automatic tool radius correction, automatic closure of the contour and the graphic display and process simulation. Precision in following the contour is ensured by ball screws, which achieve an optimum result in combination with the automatic delay in movement when radii are being processed.

The dust is extracted directly under the work area. The sawdust is pulled down by the wire and then directly extracted.
