Grinding machines

Complete digital control system

For more than fifty years Duplomatic has been present on the machine tool market, i.e. a sector under constant development where the request for a production increase is always combined with machining accuracy. It is the case of the tangential grinding procedure with the complete digital control of the table movement (speed and movement reversal are completely managed with a closed loop). In the last years the role played by electronics in the machine tool sector has become more and more important, to such an extent that the final user can guarantee a growing accuracy level in machining precision.

By cooperating with another sector leading company, Duplomatic has developed a tangential grinding procedure for flat surfaces where the electronic section plays a fundamental role.

The tangential grinding machine for flat surfaces with complete digital control is featured by a structure made of Meehanite cast iron in order to ensure the highest rigidity without vibrations, grinded and scraped guides with a Turcite® coating on the coupling of the base of the transversal table and a high pressure cartridge spindle which guarantees the highest accuracy during the flat, geometric and shaped grinding procedures.

The machine is equipped with a digital 840DI CNC from Siemens supplied with drives, motors and position control performed via Heidenhain linear scales whereas the transversal table is moved through an hydraulic circuit with a Duplomatic DXJ3-DOL/40 proportional valve with integrated electronics; the valve is controlled via Heidenhain millesimal scales in order to obtain, together with the standard swinging, accurate positioning procedures. The table speed is 40 m/min and the positioning and reversal accuracy is equal to 0,01 mm.
The user-friendly and intuitive man-machine interface allows to import geometries from DXF files in order to create any sort of profile.
