- Axle Drives With our balancing machines for front and rear axle transmissions, the measured unbalance is corrected by drilling into the drive flanges of the transmissions (welding optional). We support you with our interdisciplinary expertise in the production of front and rear axle transmissions from the initial idea to the design stage through to series production.

Frequently asked questions
Answers to the most common questions about our products and services
It measures machine-tool spindle growth caused by thermal and centrifugal effects, using a suitable ring as target, with an additional temperature output.
The net span is 500 µm with a 100 µm start offset, giving a 100–600 µm interval from the head.
Do not transfer it automatically. The 250 µm OEM option is a separate configuration and needs performance evidence explicitly covering it.
No. The manufacturer prohibits shortening it. Head, cable and controller form a calibrated system; choose the cable configuration beforehand.
No. Analog update is 64 kHz, while frequency response is 2 kHz. Use frequency response for dynamic-measurement planning.
