All of our eroding machines can alternately erode and grind in one clamping. This not only saves time, but also increases flexibility and precision as the clamping does not need to be adjusted. This combination of eroding and grinding is called the 'Two-in-one principle'.
The eroding machine can also be used as a tool grinder for production and re-sharpening of carbide tools. The change of tools from PCD material to carbide tools is "hot," because the change between PCD tools and carbide tools and vice versa can be made automatically.
WALTER introduced this combination of eroding and grinding at the EMO 2001. And since then, we have continued developing the 'Two-in-one concept'. Even at that time it was clear that a strong grinding spindle was essential for a perfect production result, and that many tools can be made more efficiently by the rotational eroding than wire EDM.
In 2006 WALTER introduced a software module that multiplied the benefits of the "Two-in-one concept" by making it possible to automatically switch in an electrode/grinding wheel changer.
HELITRONIC DIAMOND EVOLUTION
The efficient HELITRONIC DIAMOND EVOLUTION combined eroding and grinding machine can grind and erode tools in one setting.
HELITRONIC POWER DIAMOND 400
The HELITRONIC POWER DIAMOND 400 tool eroding machine can erode tools made of PKD/CBN material and grind tools made of high-speed steel/carbide.
