RX 10 is a rotary axis calibration system which provides fully automated axis calibration to +- 0.5 arc second accuracy.
It is used in conjunction with the ML 10 lasersystem, allowing rotary axes to be calibrated to laser accuracy.
This patended method of calibration has revolutionised the measurement of rotary axes. Automated testing enables a rotary axis to be checked in a very short time. This represents a massive time saving over traditional methods.
RX 10 operates either in horizontal, vertical or even upside-down position for easy calibration.
Another fundamental advantage of RX10 versus traditional measurements is that indexing increments can be varied over the whole measurement range.
Data output is provided either in arc seconds or µmdegrees and can be compensated by us within the machine`s controller.
Our measurement software corresponds to the recommendations of the VDE/DGQ guidelines regarding the evaluation of the angular positioning accuracy. Hereby positioning deviation, positioning uncertainty, minimum, maximum and average variance of positioning as well as minimum and average deadspot have to be measured.
