Title:
HONING METHOD AND HONING DEVICE
Document Type and Number:
Japanese Patent JP3042276
Kind Code:
B2
Abstract:

PURPOSE: To unity the inclination of cross hatches, formed on the inner surface of a machined hole by making the rotating speed and axial moving speed of a honing head at the time of final finish-machining lower than each speed at the time of pre-stage machining before the final finish-machining.
CONSTITUTION: A honing head 3 is rotated by rotating drive mechanism 29, formed of power transmission mechanism 21 and rotating motor 23, through a rod 19 and an expanding pressure cylinder 15. The honing head 3 is further moved vertically by vertical drive mechanism 31, formed of a vertical moving cylinder 25 and a piston 27, through the rod 19 and the expanding pressure cylinder 15 to grind the inner surface of a machined hole 1. At the time of final-machining, the rotating speed and axial moving speed (vertical moving speed) of the honing head 3 holding a grinding wheel 11 are respectively lowered by a control circuit 33 so as to stabilize the movement of the honing head 3. The inclination of cross hatches formed on the inner surface of the machined hole is thereby made uniform.
