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.

This machine can run for a long time without any operator intervention, and users can machine finished parts from slug stock or cast blanks while achieving the same high productivity as if they were machining from barstock, the company says.
