Assured performance

High-speed spindles from GMN are designed for extremely high machining speeds in machining. Their performance profile is for maximum key speed values which achieve the outstanding smoothness.

Spindle groups

GMN spindles cover a broad speed range - as grinding spindles of up to 250,000 RPM - and are extraordinarily resilient. You can obtain the best spindle for your tasks from a broad series of designs and options.

Housing designs

GMN offers several housing forms for its high-frequency spindles, which can be combined as needed with various spindle types.



The functionality, effectiveness and lifetime of your spindle can be increased with the right accessories.

IDEA-4S for continuous spindle monitoring and improved production performance

IDEA-4S stands for “Integrated Data Acquisition and Evaluation for Spindles”. It helps to achieve greater power and better performance with all kinds of drives. However, the small embedded system can do even more: it ensures the perfect IIoT (= Industrial Internet of Things) connection of the drive components and the digitization of the drive technology.

It is suitable for machine tool motor spindles, such as milling spindles and grinding spindles, and for other drives and test bench motors.
