When Mantz Automation decided to upgrade its EDM capabilities to reduce outsourcing and have more control over the EDM process, it started with the addition of an MC Machinery Roku Roku high-speed VMC. The company then purchased MC Machinery’s Ingersoll Eagle V550 graphite machining center and recently added an Ingersoll Gantry 1400 sinker EDM.
Graphite machining can be a shop floor bottleneck, particularly with simultaneous complicated projects.
“A big shop can become very small,” Doerfert said. “That’s when the Ingersoll five-axis graphite machining centers come in–it can build more electrodes faster and more efficiently. The Ingersoll Gantry sinker EDM can do both very large and smaller molds while reducing the amount of carbon used. We can set up more projects on one table and run multiple projects unattended.”
Adding machines with automated functionalities became the path to achieving lights-out operation.
One area where the manufacturing worker shortage has not been an issue is finding skilled operators for its multiple Mitsubishi EDMs, Doerfert said.
“The Mitsubishi EDMs are built stronger and are very accurate,” he said. “And there is a deep well of manpower because they are so ubiquitous within the tool-and-die community.”
In the high-capital tool-and-die business, having high-quality, durable equipment that is fully supported by the Mitsubishi subsidiary’s regionalized service team is important, Doerfert said.
MC Machinery’s service is “spot on,” allowing Mantz Automation to meet challenging turnaround times and avoid downtime, he said.
