Hardinge released two new vertical machining centers (VMC) designed to machine components for the aerospace, medical, electronic, defense, automotive, power generation, and other industries.
Both VMCs, known respectively as the GX 250 5F and GXR 320 5F, feature broad work envelopes and small factory footprints. The GX 250 5F has a work envelope of 11.8 by 15.6 by 16.9 in with a 1,181 inches-per-minute traverse speed. The GX 250’s 20-hp, 15,000-rpm spindle is combined with a 30-tool change arm.
The GXR 320 5F’s faster traverse speed of 1,693 inches per minute operates in a larger envelope of 20 by 24 by 20 in. Its larger swing-arm automatic tool changer can quick-change between 48 tools for a 25-hp, 12,000-rpm spindle.
The GX 250 5F and GXR 320 5F Bridgeport VMCs are designed to perform 4+1 machining, in which four axes simultaneously machine a part while a separate axis is devoted to positioning. This technique is used to limit setup and operating time.
