GROB Group
GROB Systems Inc. will demonstrate a range of 5-axis machining applications on its compact G350 Generation 2 universal machining center at PMTS in Booth #6047 at Huntington Convention Center, Cleveland, Ohio from April 18-20, 2023. Attendees can see how GROB meets and exceeds the demands of aerospace, medical and die/ mold machining, and GROB personnel will be on-hand to answer specific customer application questions.
GROB machining centers are made in the U.S.A. at the GROB Systems 400,000ft2 full production facility in Ohio and can include advanced automation solutions for dramatically increased productivity. The GROB G350 on display at the show will include a dynamic rotary table with a 200rpm B-axis with infinite rotation, and a maximum rotation of 360° in the A-axis. This G350 Generation 2 machining center is equipped with a Siemens 840D sl control, 16,000rpm spindle, 117-tool holding capacity, and an HSK-A63 tool interface. The GROB G350 will feature a pyramid fixture holding 3 parts at once – one each for an aerospace, medical, and mold part.
Multiple machining demonstrations will be held throughout each day on the G350 5-axis universal machine, and three applications will be featured.
Medical bone plate machined from titanium will also demonstrate the ability to rough and finish on the same machine to produce a complete part in one setup. The finished part will be held by two small tabs, so part removal by hand is fast and easy. With the GROB G350 machine’s unmatched part accessibility via its tapered spindle nose and positive angle reaching capability, challenging features can easily be reached.
Aerospace IBR/ blisk segment machined from titanium will showcase the ability to rough and finish on the same machine resulting in high precision. Fast and accurate rotary axes will produce an excellent finish on the leading and trailing edge of the blade, and accurate tool-to-tool blending will generate a smooth blade-to-hub blend.
Injection mold machined out of P20 mold steel has many adjoining part features that require high machine accuracy for smooth surface blending. The G350 machining center’s horizontal spindle design and multiple coolant functions will also prevent the recutting of chips during the machining of a pocket feature.
