EDM from MC Machinery Handles Larger Parts
MC Machinery’s MV2400-ST, an electrical discharge machine, is specifically designed for larger-part production, capable of performing submerged cutting up to 16.5" deep.
MC Machinery’s MV2400-ST, a wire EDM, is specifically designed for large-part production, capable of performing submerged cutting as deep as 16.5". With an annealing length of over 21", its automatic wire threading system can thread the maximum workpiece height both at the start point and through the gap if needed for a broken wire recovery, the company says.
The EDM also features Mitsubishi’s M800-series control with a 19" touchscreen providing easier user interface than previous models. The control uses rotational and tilting functionality while showing job monitoring and other important information in a single view. The new navigation interface is also said to provide intuitive operation for users of different expertise.
The promise of running a wire EDM for long stretches without much operator attention is enticing, but many shops never manage to pull this off. Here are tips to make it happen, as offered by Mark Cicchetti, EDM technical director for Absolute Machine Tool’s Accutex EDM product line.
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.
Hummingbird takes on machining work that is too small for most shops to handle. In fact, Hummingbird tries not to handle it either. To accurately machine the tiniest parts, this shop relies on processes that are as hands-off as possible.
