Tools of diameters from 1 to 32 mm and up to 185 mm long can be accommodated by the unit, which uses Walter’s standard robot pallets for blanks and finished tools. Indeed, up to 500 tools of 3 mm diameter can be handled, with each tool change taking 27 seconds.
Walter Ewag is also introducing a compact wheel-changer for the Helitronic Mini Power and Helitronic Diamond Evolution machines that accommodates six grinding wheel sets or electrodes having a maximum diameter of 150 mm. Use of the wheel-changer on machines featuring Walter’s belt-driven spindle extends tool grinding and erosion capacity by 40 mm, to grinding lengths of 225 mm.
