Maximum repeat accuracy
KOMET KomTronic® U-axis systems now also have a direct encoder
KOMET KomTronic® U-axis systems will also be able to be equipped with a direct encoder in future. As an alternative to the usual indirect encoders, it can be used as a modular component and significantly improves repeat accuracy.
The standard version of the mechatronic KOMET KomTronic® U-axis systems is equipped with an indirect encoder that is integrated in the drive unit. In the course of the KOMET KomTronic® HPS (high precision systems) technology project for high-speed machining, a new direct encoder was developed in addition to the modularisation and miniaturisation of the individual components. It takes into consideration the mechanical disturbance variables, i.e. the motor shaft, the transmission and the threaded spindle. The direct measurement system now allows measuring directly on the slider, followed by a reaction with the control system. Although precision was already high, this still constitutes yet another significant improvement in repeat accuracy. This is associated with better compensation methods for progressive wear. If both encoders for indirect and direct position measurement are combined, the position difference and the backlash can be observed over time, meaning that it is even possible to set up a wear (i.e. condition) monitoring system.
This optional type of encoder can be selected by the user depending on requirements. It is a modular component in the construction kit of the KOMET KomTronic® U-axis systems.
