Larger capacity Helitronic two-in-one tool grinding & erosion machine

Walter Ewag UK has announced that its two-in-one Helitronic tool grinding and erosion concept has been extended to tools up to 420 mm long and with diameters of 3 mm to 315 mm.

The new Walter Helitronic Vision Diamond 400L machine can effectively and efficiently grind and erode, in a single set-up, rotationally symmetrical precision tools.

Walter’s two-in-one grinding/erosion process enables the machine to automatically switch between the production of PCD tools – including the latest styles of PCD tooling - and carbide tools, and eroding and grinding, in a single clamping cycle.

The Helitronic Vision Diamond 400L features a mineral cast base and portal construction for extreme rigidity; converting the high dynamism of the digital drives into low-vibration erosion and grinding precision.

The machine features Walter’s Fine Pulse Technology eroding concept which sets new standards in terms of PCD tool surface quality, cutting edge roughness and process reliability.

The new Helitronic Vision Diamond 400L also features an inexpensive belt-driven spindle for the automatic switching of eroding and grinding wheel sets, complementing the options of dual and motor spindle versions.

Electrodes and grinding wheels up to 254 mm diameter can be handled, and up to 24 electrodes and/or grinding wheel sets can be used with the aid of optionally available wheel changers. A variety of different loader solutions are available for tool changing via a six-axis Fanuc robot. The new machine is provided as standard with Walter’s Helitronic Wizard-enabled Tool Studio grinding software, which includes optional functionality for erosion.
