Abstract

이 발명은 피가공물의 내면에 호닝가공을 행하고 있는 동안, 피가공물의 내면에서의 윗부분으로부터 아래부분까지 냉각액을 공급하여 균일한 냉각을 행하고, 균일한 호닝 다듬질을 가능하도록 한 호닝 가공방법 및 그 가공방법에 이용하는 호닝헤드 구조를 제공하고자 하는 것이다.The present invention provides a honing processing method and a processing thereof in which a cooling liquid is supplied from an upper portion to a lower portion on an inner surface of a workpiece to perform uniform cooling while honing processing is performed on the inner surface of the workpiece, thereby enabling uniform honing finish. It is to provide a honing head structure for use in the method.

피가공물(CB)의 내면(B)을 회전이 자유롭고 또한 왕복운동이 자유로운 호닝헤드(1)의 앞끝단의 호닝툴(7)에 설치된 복수의 숫돌(9)로 호닝가공을 행하는 경우 의부로부터 공급된 냉각액을 상기 호닝헤드(1)에 설치된 냉각액 도입용핀(5A), (5B), (5C)으로 호닝툴(7)의 외주부에 형성된 냉각액 도입용 홈(11)으로 도입함과 아울러, 이 냉각액 도입용 홈(l1)으로부터 상기 냉각액을 상기 피가공물(CB)의 내면(B)으로 도입하여 냉각하는 것에 그 특징이 있다.The inner surface B of the workpiece CB is supplied from the foot when honing with a plurality of grindstones 9 provided on the honing tool 7 at the front end of the honing head 1 freely rotating and freely reciprocating. The coolant is introduced into the coolant introduction groove 11 formed in the outer circumference of the honing tool 7 by the coolant introduction pins 5A, 5B and 5C provided in the honing head 1, and the coolant The coolant is introduced into the inner surface B of the workpiece CB from the inlet groove l1 and cooled.
