Possesses hole warping modify feature the multiple spindle hole machine

摘要

PURPOSE: To provide a multispindle drilling machine in which a spinle row face itself can be easily corrected about the center of spindles, as a center of rotation, and which has a simple construction. ;CONSTITUTION: Push plates 10A, 10B, 11A, 11B are provided on a holding means 5 across an axis row line C so that the plates 10A, 11A are located in opposition to the plates 10B, 11B so as to be movable back and forth. When a curvature of a hole is being generated so as to incline the line C clockwise, the plates 10A, 11B are advanced and at the same time the plates 10B, 11A are retracted.;COPYRIGHT: (C)1997,JPO
