Abstract
A boring bar adjusting mechanism for automatically correcting an offsize boring cutter. The mechanism includes a measuring gauge and an adjustable boring bar, each mounted in separate tool holders and each stored in the tool storage magazine. The measuring gauge is transferred to the spindle by the machine tool transfer mechanism after a conventional boring operation is completed to measure the work-piece bore. If the bore is inaccurate, the measuring gauge is removed and the boring bar, is loaded into the spindle. The cutting element of the boring bar is adjusted automatically by an adjusting mechanism in response to the bore size measured by the measuring head so that it will machine an accurate bore.
