Offering fast and accurate collet change from the front of the machine, the spring-loaded GDS system offers a clamping length of 50mm for tools up to 20mm diameter on the Helitronic machine range (up to 12mm on the Helitronic Mini Automation and Helitronic Micro) and boasts impressive concentricity and repeatability values both of 0.002mm.
Additional time-savings are also on offer with the automatic (rather than manual) measurement of machine axis positioning via electrical contact.
Available soon as a retrofit for Helitronic tool grinders with Fanuc CNC systems, a setting disc with electrical isolator is easily and quickly interfaced with the control. The functionality not only eliminates the possibility of human error but also frees up operators for other tasks.
Together, the two developments further enhance the cost-effectiveness of Walter Helitronic tool grinders.
