The Hardinge Quest Super-Precision GT27 gang-tool turning center is designed for machining small diameters and tight-tolerance parts, such as those required for medical devices. The turning center provides a continuous machining accuracy of 0.0002" on diameter, part-roundness variation of 0.000015" and part surface finish of 0.000008". It can machine bar ranging to 1 1/16 " (27 mm) and chucked parts as large as 4" in diameter using a step chuck. The turning center can be used as a stand-alone unit, a high-capacity system with a bar feed, or a fully automated system with a robot.
The machine’s top plate fastens to the dovetailed cross-slide and is interchangeable for quick and accurate tooling changes that can be performed in less than a minute, Hardinge says. Pre-tooled top plates can be interchanged within 0.0002" repeatability to produce a new part or family of parts. A quick-change collet-ready spindle provides increased rigidity and gripping power because the collet seats directly in the spindle with minimum overhang from the spindle bearings. The Harcrete machine base is said to improve dynamic stability and decrease vibration at the spindle for longer tool life.
