MMS NOVEMBER 2018 98 mmsonline.com BETTER PRODUCTION GRINDING EQUIPMENT bases, rails and other mounting surfaces, as well as parts from its contract machining divi- sion. Many different part sizes and materials would come across this machine. "On any given day, we could be grinding cast iron, aluminum and mild A36 steel," says Manufacturing Man- ager Chris Dolny. "We'll do a 4-by-2-inch part, and then we have a 30-by-70-inch part the very same day," he adds. While Moore Tool's dated surface grinder was sufficient, a good bit of manual lapping and/or scraping was still required to generate the proper geometry and surface finish for certain compo- nents. That, combined with subpar performance and reliability issues, led the company to look for newer surface-grinding technology, ultimately purchasing an ACC3280CHiQ from Okamoto (Vernon Hills, Illinois). This new machine can grind parts to a better geometry and finish, which has reduced secondary, manual operations. It has also sped the production of jig grinder and dia- mond-turning components, increas- ing the company's overall competi- tiveness in those markets. Although the surface grinder the company had been using was very old, the decision to replace it was not easy. "It took us a few years to make this decision to invest in new surface grinding technology," says Newman Marsilius IV, Moore Tool's vice president and general manager. In fact, the company made the decision just in time. On the same day the new machine's purchase order was placed last year, the old machine went down with a fatal electrical error. "Luck- ily, Okamoto was bringing in a machine from Grooving • Turning • Boring • Threading • Parting Profiling • Form Tooling • Special Tooling • Face Grooving With over a million standard tools, we've got the "ings" covered. INTERNAL GROOVING INTERNAL FACE GROOVING INTERNAL THREADING EXTERNAL GROOVING EXTERNAL FACE GROOVING EXTERNAL THREADING "The new machine is allowing us to make parts more efficiently and with better geometry in less time, so it ultimately makes our products a little less expensive and maybe a little bit more competitive in the market."
