Sinker EDM Features Simplified Control Mechanism
Sodick’s eco-friendly AG100L sinker EDM features a simplified control mechanism that provides a direct link between the drive and the control.
The sinker EDM is equipped with linear motor drives on the X, Y and Z axes and a glass scale feedback. A zero electrode wear circuit and a fine finishing circuit are standard. X-, Y- and Z-axis travel measures 47.24" × 25.59" × 19.69", respectively. The machine can accommodate workpieces weighing as much as 11,000 lbs.
By systemizing die making into repeatable steps, Dies Plus, a division of Otto Engineering, is using its machinists to effectively make dies. This solution relies on a paperless color-coding system to convey the tolerances machinists need to hit in order for tool and die makers to do the final fitting.
Originally, wire EDM had two things going against it. It was slow, and often it left an undesirable surface finish. In the last few years, wire EDM builders have fixed the speed problem. Now they're well on their way to fixing the surface finish problem.
A new breed of power generators for wire EDMs has options for reducing, even eliminating, one of the unwanted side effects of this very versatile metalcutting process.
