The Quest CHNC turning center is available with either a 27-mm, 5C or a 42-mm, 16C collet-ready spindle. The machine is designed for high accuracy and quick job changeover to meet the demands of the medical, aerospace, defense and computer/electronics industries. This design configuration allows the use of top plates and tooling used on thousands of previous-generation CHNC machine installations worldwide.
The turning center is built on the same platform as the company’s Quest GT-series gang tool lathes. The Harcrete base is a proven synthetic structure that provides vibration damping, structural rigidity and thermal stability, the company says. The 7.5-kW (10-hp) drive system is a complete Fanuc motor and drive system. A full complement of Hardinge workholding devices is available to accurately grip workpieces including collets, step chucks, expanding collets and Sure-Grip jaw chucks.
Gang tool-style, pre-set, tooled top plates (8-position or 4-position) can be interchanged in minutes, reducing overall setup time, the company says.
The Hardinge/Fanuc 21i-T CNC includes a 0.000010″ (0.00010mm) programmable resolution/tool offset capability. Standard features include an Ethernet card, custom macro B programming, extended part program edit, and a run time and parts counter.
