HONING PROCESSING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a honing tool capable of prolonging a life of the honing tool and obtaining high dimension accuracy for a long period of time by inhibiting a reduction of surface roughness of polishing processing. SOLUTION: The honing processing device is provided with a work retaining tool for retaining a cylindrical work; a honing head disposed advanceably/ retreatably against the work retaining tool and butted to an inner periphery surface of the work at an end of the work retaining tool side; a honing tool having a guide part of a larger diameter than an outer diameter of the honing head at a center side; a positioning plate having a guide hole engaged with the guide part of the honing tool and carrying out positioning in an axis vertical direction of the honing tool; and a lubricating means for feeding a lubricant to the inner periphery surface of the work through the guide hole of the positioning plate. An axially extending induction groove is formed on the inner periphery surface opposed to the guide hole of the positioning plate.
