New Laser contour check for improved non-contact tool measurement


Laser Contour Check is the new non-contact cutting tool measurement innovation that ensures high-precision and fast in-process measurement of tool parameters in Walter tool grinding and eroding machines.

Walter Ewag UK reports that the new development utilises blue laser technology in conjunction with an intelligent measuring system to accurately and efficiently measure various features on cylindrical tools from 1 to 52 mm diamenter. Any deviations are compensated for directly during the machining process.

Laser Contour Check’s analogue laser beam measures a tool’s entire contour rather than measuring at specific points as with tactile or digital methods. Laser technology also avoids possible damage to the tool’s cutting edges as well as measuring errors that could occur due to probe tip wear during tactile measuring routines.

A short measuring time of just 16 seconds, including cleaning, for diameter measurement (depending on tool type) ensures high productivity, and optimised sequences for cleaning and compensation can be easily and quickly programmed and adapted by the operator.

The measuring system – which will be available as an option for Walter’s extensive range of tool grinding and eroding machines – is integrated directly into the machine’s working area and moves into position when required.

Walter Ewag UK says the blue laser beam used offers improved accuracy compared to a conventional red laser. Blue lasers have a shorter wavelength and so optimise the laser beam geometry and reduce the effects of diffraction.
