ADAPTIVE GRINDING METHOD AND ADAPTIVE GRINDING DEVICE

摘要

PROBLEM TO BE SOLVED: To adaptively grind a columnar unfinished article 10f by a centerless grinding machine CLG so as to properly fit to an inner peripheral surface with the inner peripheral surface of a finished cylinder 9f by improving a centerless grinding technique. SOLUTION: Data by measuring the inner peripheral surface of the finished cylinder 9f by an inner diameter measuring instrument 11 is inputted to an automatic control circuit CPU. The automatic control circuit controls a horizontal turning board 6 of the centerless grinding machine so as to grind and finish and outer peripheral surface properly fitted to the inner peripheral surface of the finished cylinder 9f. In short, a stroke of a lower slide 7 is also controlled. A measured cylinder 9g used as a reference and a column 10h of a finished product ground so as to be adaptive to this cylinder are placed on an adaptive pallet 13, and hold a contrapositive relationship therebetween.
