HARDINGE INC. QUEST GT27SP HORIZONTAL MACHINING CENTER

Technical Description

The Hardinge Quest GT27SP is a precision CNC gang-tool turning center engineered for high-accuracy small-part production. This horizontal machining center features a robust 1.060" maximum bar diameter capacity with an 11.760" swing diameter, enabling workpieces up to 4.000" in turning diameter and 3.000" in turning length. The machine is equipped with a powerful 10 HP main spindle capable of speeds up to 8,000 RPM, paired with a 4.000" chuck diameter for secure workholding. The gang-slide tool carrier accommodates up to 10 turning tools and 2 rotary tools, with one simultaneous cutting tool capability, providing flexibility for complex multi-operation cycles. The machine operates on two axes with 11.970" X-axis travel and 11.060" Z-axis travel, delivering rapid traverse rates of 708 IPM on both axes for efficient cycle times. An auxiliary 0.70 HP rotary tool spindle rotating at 6,000 RPM enables secondary operations such as drilling and milling without requiring part reorientation. The system is controlled by a Fanuc 21iT 32-bit CNC controller featuring custom macro B, rigid tapping, and laser ball-bar tested dynamic balancing for superior part accuracy. Renowned for exceptional precision, the QUEST-Series delivers .000015" part roundness and 0.0008" (Ra) surface finish capabilities. The machine's Harcrete polymer composite base provides vibration isolation and thermal stability, weighing approximately 5,700 lbs and occupying 70" × 58.7" × 62" of floor space.
