MONZESI MONZA

Monzesi, today, is one the main manufacturers in the world of high precision grinding machines, specifically for:

  • Centerless grinders – Monza division;
  • Double disc grinders – Viotto division;

Monzesi’s mission is to achieve the perfection in grinding, continuing a long tradition of innovation in engineering and customized solutions supplied to a large number of customers worlwide.

A century of experience. A piece of history in the machine tool industry. Much more than a plain machine tool builder.

This is what today Monzesi represents, in its continuous production of centerless grinders and double disc grinders. This is what Monzes has been in the past, and what it will be for the future generations.

The MONZA models Line 20 are built upon the foundation of main characteristics which have been distinguishing the Monzesi centerless grinding machines for almost a century: strength, ergonomics and reliability. The main technological innovations of the Line 20 models:

  • The INFEED slide system has been modified allowing it to arrive closer to the Grinding Wheel Housing. The design improvement offers added strength, as well as full support under the workrest when grinding very small diameters and also when the grinding wheel is running at its smallest useable diameter.
  • The dressing process, in the versions where the translation is not controlled by full CNC, is controlled by an electric motor. All hydraulics have been removed from the dressing functions.
  • The FULL CNC Dressing versions have the option of designing and controlling complex wheel profiles directly on the machine using our latest CAD/CAM graphical software.
  • All the machine axis motors use DIGITAL DRIVES (transducers). The Grinding wheel motor is availble with Constantant Peripheral (Surface) Speed (CSS), as well as Automatic Wheel Balancing (AWB).
