PROBLEM TO BE SOLVED: To perform machining with fine surface roughness at high machining speed and with high efficiency. SOLUTION: A cutting machine includes a work head part 13, a workpiece rotating means 14, a cutting tool 25, a cutting tool rocking means, a cutting tool rotating means, first and second moving means moving the cutting tool 25 in directions of axes X and Z, a rotation angle detecting means detecting the rotation angle of the work head part 13, a rocking position detecting means detecting a rocking position by the cutting tool rocking means, a first movement position detecting means detecting the distance from the rotary shaft center of a piston base material 40 to the cutting tool 25, a second movement position detecting means detecting the position of the cutting tool 25 to the rotary shaft direction of the piston base material 40, and a control part controlling driving of the cutting tool rocking means so that the outer peripheral surface 40a of the piston base material 40 is subjected to rough cutting and finishing cutting by the cutting tool 25 and the cutting surface of the cutting tool 25 comes in contact with different regions of the surface of the piston base material 40 in the rough cutting and finishing cutting, respectively.
