Due to cooperation with technical universities and research institutes over the years, GMN is constantly optimizing spindle technology using the latest research data. GMN spindles are exclusively produced in our home factory in Nuremberg, Germany. There are spindle types in which the motor is flanged.

Over 80 years of experience in spindle technology High Precision spindle bearings from our own factory Excellent performance Reliable operational safety Use of quality components of selected premium manufacturers Consistently outstanding quality characteristics Wide selection of equipment options Special solutions in every lot size hour spindle service.

Oil-air lubrication for higher reliability. Tool and die manufacturing Spindles for these applications such as the HC and HCS series provide the highest precision at very high speed for sometimes micro-precise manufacturing results.

GMN also makes tool and dressing spindles for energy regeneration or test stand motors. Oder benutzen Sie unsere Sitemap zur Navigation. The spindle may only be operated in a direction of rotation when mounted by a thread in the center of the shaft.

FAQ Spindles

All open questions can be clarified with our psindle service and our representatives. The topics and contents of the training is established to meet customer requirements.

There are, for example, sensors for monitoring the tool interface for spindles with automatic tool changefor measuring the shaft displacement, for monitoring the motor temperature sensor suitable for the controller or frequency converter to be used and bearing temperature PT sensor. GMN Spindle Service With more than ten GMN authorized GMN service centers throughout the spindls, we offer our customers over 80 years of experience in the development and production of machine spindles.

High-frequency motor spindles for automatic tool change such as the HCS seriesoften also used for internal or external minimum volume lubrication, are used here. Training GMN offers qualified training at customer sites as well as in our facilities, in the theory and practice of the proper use of GMN spinsle spindles.

Slindle standard tool interface — fitting bores with flat contact face Lubrication: PTC for motor temperature monitoring. Use of hybrid bearings with ceramic balls for high stiffness:: Precision bearings, solid preloaded:: Nomenclature, spindle selection, lubrication, calculation Maintenance: Their performance profile is for maximum key speed values which achieve the outstanding smoothness. Are the motor spindles fitted with sensors? For which applications are GMN spindles used?

Heating takes place due to the current flow through the coils, which may not exceed a temperature which is appropriate to the insulation class. Here ist pays out to use our mostly own-manufactured high-precision ball bearings.
