PROBLEM TO BE SOLVED: To increase machining efficiency by concentrically arranging a machining tool having the outer diameter of a prescribed size and a machining tool having the inner diameter larger than the prescribed size on a support section. SOLUTION: A grinding wheel 53 and a lapping surface plate are coaxially fitted to the same flange 51. A prescribed cut quantity is applied to a machining tool 50 by a positioning mechanism 70, and it is rotatively driven by a rotary drive device 60, then a slider is feed-driven at the prescribed speed. The grinding wheel 23 of the machining tool 50 is brought into contact with a work W for grinding. Pressing force is applied to the machining tool 50 by the positioning mechanism 70, and it is rotatively driven by a rotary drive device 30. The slider is reciprocated to reciprocate the work W and the lapping surface plate 55 for polishing. |
