The encoder system is located behind the release unit and behind the spindle nut and unfortunately cannot be removed “just like that”. We deliberately go one step further and take care of the complete conversion and thus the improvement of the system. This requires specially trained and highly qualified personnel, and of course the appropriate assembly tools must be available.
Successful repair involves safely removing the encoder wheel from the spindle shaft. The sensor is then replaced. We work with a mechanical cog wheel and robust sensor technology. This encoder wheel remains sufficiently stable even if liquid gets into it.
Added to this is our automatic amplitude stabilisation, which compensates for radial air and bearing wear.
After approx. 5,000 operating hours, the position of the sensor can change vis-à-vis the encoder wheel. The encoder system is located on the back of the motor spindle and makes quick repairs difficult.
The cause of the problems with the spindle encoder is the radial air of the floating bearing. Micro-particles, chips or coolants cause contamination here – natural wear and tear does the rest. Work on the spindle encoder poses a great challenge even for experienced technicians, as ultimately, work has to be done directly on the spindle shaft. As a result, the manufacturer usually wants to replace the encoder, but then discovers that this cannot be done at the customer’s site.
The Spindeldoctor’s BLACK LABEL SERIES encoder system extends the life of your spindle. In addition, the replacement of the encoder system by the Spindeldoctor offers further advantages:
