摘要 |
PROBLEM TO BE SOLVED: To provide a means for adjusting the enlargement and reduction of an outer diameter of a reamer mounted on a point of a rotary sheath shaft by rotating a rotary shaft inserted into a rotary sheath main spindle by a predetermined angle by the manual switch operation not by the wrench operation which needs the experience and the perception of an operator. SOLUTION: In a bore finishing machine 1, a rotary shaft 5 rotated by one rotation predetermined angle through a driving pinion 4, is inserted into a rotary sheath main spindle 2 driven by a main spindle driving motor M1 through a transmission system 3, and an outer diameter 6a of a reamer 6 mounted on a point of the rotary shaft 5 is enlarged and reduced along a taper cone 9 by the vertical motion by a screw pitch of an enlargement and reduction bar 8 thread-mounted on a rotary sleeve 7 inside of the reamer body 6.
