Chuck Helps Restore Thin-Walled, Hardened Parts To Roundness

摘要

Heat-treating a delicate, thin-walled workpiece in order to achieve the desired hardness often results in the part coming back "out of round." Although finish turning the part can provide some measure of roundness improvement, it is often not enough to meet specifications. To address this problem, workholding solution provider Hardinge has developed a chuck designed specifically to tackle the problem of thin-walled, hardened parts that require high roundness accuracy. In a recent study, the company reported that a hard-turning process incorporating the chuck improved roundness approximately 10 times better than conventional workholding devices when used on the very same machines.
