5-Axis Machine Features Pyramid Fixture to Hold 3 Parts at Once
GROB System Inc.'s machining centers are made in the U.S.A. at the GROB Systems 400,000 sq. ft. full production facility in Ohio and can include advanced automation solutions for dramatically increased productivity.
The GROB G350 that was displayed at IMTS includes a dynamic rotary table with a 200 rpm B-Axis with infinite rotation, and a maximum rotation of 360° in the A-Axis.
The G350 Generation 2 machining center is equipped with a Siemens 840D sl control, 16k rpm spindle, 117-tool holding capacity, and a HSK-A63 tool interface. The GROB G350 features a pyramid fixture holding 3 parts at once -- one each for an aerospace, medical, and mold part.
GROB held multiple machining demonstrations at IMTS, including the following on their G350 5-axis universal machine:
- Aerospace IBR/ Blisk Segment machined from titanium showcased the ability to rough and finish on the same machine resulting in high precision. Fast and accurate rotary axes produced an excellent finish on the leading and trailing edge of the blade, and accurate tool-to-tool blending generated a smooth blade-to-hub blend.
- Medical Bone Plate machined from titanium demonstrated the ability to rough and finish on the same machine to produce a complete part in one setup. The finished part was held by two small tabs, so part removal by hand is fast and easy.
- Injection Mold was 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 prevented the recutting of chips during the machining of a pocket feature.
