WALTER has unveiled a new innovative option Laser Contour Check for non-contact measurement of various tool parameters on cylindrical tools in tool grinding and eroding machines.

In addition to tactile measurement in the grinding and eroding machines, WALTER now offers a new and innovative non-contact option: Laser Contour Check. The new blue laser, in combination with the intelligent measuring system for high-precision measurement of various tool parameters on cylindrical tools with diameters from 1 to 52 mm, avoids possible damage to cutting edges or measuring errors that can occur due to wear on the probe tip during tactile measurements. Measurements are made directly in the analogue laser beam on the entire tool contour and not only at specific points as with the tactile or digital measuring method. 

Deviations can thus be compensated directly in the process. A short measuring time including cleaning of approx. 16 seconds (depending on the tool type) for diameter measurement ensures increased productivity. Optimised programme sequences for cleaning and compensation can be programmed and adapted by the operator. The measuring system is integrated directly into the working area of the machine and moves into position when required. The blue laser beam used offers improved accuracy compared to the conventional red laser, as blue lasers have a shorter wavelength, thus reducing diffraction effects and optimising the laser beam geometry.
