More than ever in the grinding business, the focus is on the price per part, whilst maintaining a high quality standard for the final product. That’s why all developments strive to shorten grinding times whilst increasing production safety.
Hommel-Movomatic’s new generation of digital in-process gauge heads let you optimise grinding processes easily and at an affordable price.
As early as 1953, the Swiss manufacturer Hommel-Movomatic launched the first ever in-process gauging systems. These were then further developed, leading to the introduction of the first digital gauging systems with an endless list of advantages for the user:
The new DM400 gauge head is a good complement to the range of digital heads currently available. Whilst the existing Hommel-Movomatic product range focuses on high precision, the new DM400 is designed to address the needs of mass production of standard parts such as transmission shafts, camshafts, and valve spools – and to provide high precision even under harsh or extreme conditions.
The highly robust construction of the DM400 grants the high degree of reliability that characterises all Hommel-Movomatic products.
The DM400 can also be equipped with the crash-safety gauge arms. Available only on the DU200 until now, this option has convinced many users: it prevents all damage to the gauge head in case of a collision with the workpiece or one of the machine components. This feature will significantly reduce any loss in time and profit due to production interruptions.

The DU200 is the solution offered by Hommel-Movomatic for the production of small series, where a high level of flexibility and a short adjustment time are crucial.
Indeed, adjusting to various diameters is quick and easy – no tools required, one knob, easy to access, very few steps.
The ideal complement to these new gauge heads is Hommel-Movomatic’s newly developed numerical control: the ESZ400. Modular and flexible in design, this neat, compact device is particularly easy to install when used with a Profibus interface for the grinding machine: indeed, the entire electronics can be fitted into the electrical cabinet of the machine.
This new generation remains faithful to one of Hommel-Movomatic core values: service.
