Honing method and honing machine

摘要

A honing processing technology for making uniform the load applied to honing grindstones by cooperating the reciprocal motion of the honing grindstones with the feeding and expanding motion at high precision by a specified relation. Servo motors are used as drive sources respectively for spindle reciprocal drive part and grindstone depth cutting part, and these two servo motors are mutually cooperated, and the feeding and expanding motion of the honing grindstones is controlled to be synchronized and tuned with the ascending and descending (reciprocal) motion of the honing tool so that the processing load applied to the honing grindstones may be averaged. Hence, without modifying the basis existing mechanical elements, the load applied to the honing grindstones may be averaged, and the honing process may be stabilized in precision and enhanced in precision.
