Techedge offers lddm laser calibration and measurement system: easier, faster and more convenient, as it checks the positional accuracy and repeatability of the machine, and helps diagnosis misalignment, looseness of ball nut, variable backlash etc. So as to set your own preventive maintenance program
The biggest advantage of using this non-interferometer, non-tripod laser system is, as the laser head is mounted in place of the tool position on the spindle and the alignment is made to the test axis, the reference plane is created as if that of a cutting tool and piece to be machined, as both the components conveniently mount on the machine eliminating errors caused by external vibration. Plus typically, fixtures and enclosures do not have to be dismantled to accommodate a tripod.
