In choosing ESPRIT to write programs for its CNC grinders and wire EDM machine, MCC Tooling found a CAM system so user friendly that the owner’s young grandchildren sometimes use it. More importantly, ESPRIT’s efficient programming is saving MCC Tooling time and money.
MCC Tooling makes and resharpens custom cutting tools, step drills, form tools and dovetail cutters, in quantities ranging from one of a kind to as many as 100 pieces, for customers in the oil, airline and medical industries. Marcus Alexander founded MCC Tooling in 1984 in Garland, Texas, with leased space and a single grinder. It has since grown into a 10-person business with a variety of machines: a Mitsubishi MV1200-R wire EDM with B-axis, a Walter Helitronic Vision CNC grinder, a Walter Power CNC grinder, a Walter Mini CNC, a TRU TECH grinder, 10 K.O. Lee grinders, a Harig surface grinder, a Gallmeyer surface grinder and a Cincinnati #2 centreless grinder. The company works with metals including carbide, stainless steel and high-speed steel.
MCC Tooling began using ESPRIT in 1999, when it purchased its first wire EDM machine, a Mitsubishi FX 10. “After hours of extensive research and vetting different programs and software, we felt ESPRIT would fit our needs and our price range perfectly,” Marcus says. “ESPRIT is user friendly, works seamlessly with our machines, and it integrates well with SolidWorks. It’s so easy that my grandchildren have come here and programmed their own things for us to cut out for them.”
In 2013, ESPRIT helped the shop move to a Mitsubishi MV1200-R with B-axis, which Marcus purchased because it could hold closer tolerances. Initially unfamiliar with the ins and outs of programming it, MCC machinists resorted at first to trial and error. ESPRIT enabled them to get up to speed quickly with the machine.
“One thing that helped us was being able to see the heads moving on the simulation in ESPRIT before running it on the EDM. This ensures we don’t waste time running an incorrect part and saves us money by not scrapping parts,” says Marcus.
The B-axis, a MMK Matsumoto, changed MCC’s world, making indexing from tooth to tooth far more accurate. MCC cuts a lot of multiple flute form cutters. Before the B-axis, making these parts took the shop several operations on different machines and a longer setup time on the EDM. Now, it takes less than two minutes to set up the B-axis, and using ESPRIT, MCC can program tools in only four additional steps.
“We can mount the tool in B-axis and walk away knowing that we’ll get the perfect tool every time,” Marcus says. “Also, with ESPRIT, we can check all the clearance and rake angles on tools to make sure they will work well and that the dimensions are correct.”
