Procedure for measuring boring pattern of deep-hole bores, especially of blind-end bores

摘要

A procedure for measuring the boring pattern of deep-hole bores (1), especially of blind-end bores is described. A probe (2) with a reflector (3) is aligned in the probe output position onto the ideal axis in the bore concerned, and an outside diameter corresponding to the bore diameter is introduced into the bore and is sunk with a measurable depth. A light beam (7) simulating the ideal axis of the bore is generated and projected onto the reflector. The bore is covered by a measuring disc (4) with a central hole (5) aligned onto the ideal axis of the bore. The light beam falls into the central hole and is reflected by the reflector onto the measuring disc. The measured data are determined by consideration of the respective bore depth with the help of the measuring disc.
