Honing processing method and honing head structure used in the processing method

摘要

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.;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.
