Compact Five-Axis Machining for Challenging Applications

June 22, 2022
Difficult production sequences for aerospace, medical, and die/ mold machining will demonstrate the range and functionality of the G350 Generation 2 machining center.

GROB SYSTEMS INC. will demonstrate a range of five-axis machining applications on its compact G350 Generation 2 universal machining center at IMTS 2022 – booth 431400, together with YG-1 Tool Co. Attendees will see how GROB’s US-built machines meet the demands of aerospace, medical, and die/ mold machining, and along with advanced automation systems for increased productivity.

The GROB G350 on display will include a dynamic rotary table with a 200-rpm 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-k-rpm spindle, 117-tool holding capacity, and a HSK-A63 tool interface. The GROB G350 will feature a pyramid fixture holding three parts at once --- one each for an aerospace, medical, and mold part.

Multiple machining demonstrations on the G350 5-axis universal machine will be featured, including:

 An IBR/ blisk segment machined from titanium will show its ability to rough and finish on the same machine resulting in high precision. Fast and accurate rotary axes will produce excellent finishes on the leading and trailing edges of the blade, and accurate tool-to-tool blending will generate a smooth blade-to-hub blend.

 A bone plate machined from titanium also will demonstrate the ability to rough and finish on the same machine to produce a complete part in one set-up. The finished part will be held by two small tabs, so part removal by hand is fast and easy. The machine’s part accessibility via a tapered spindle nose and positive-angle reaching capability means that challenging features can be reached easily.

 An injection mold will be machined out of P20 mold steel, with 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 also prevent the recutting of chips during machining of pocket features.
