PURPOSE:To reduce the size of a whole device, by providing a work elevating means, a work holding means, a swing support table, a base bed, a work swing means, a machining means, and a work moving means. CONSTITUTION:A cylinder block W held to a work holding table 2 is inclined based on a swing support table 4 by means of a work swing means 8, and machining is effected by a machining means 10 on at least one of a plurality of cylinders to form a first row. The block W is moved in the direction of the central axis of a crank shaft by a distance equivalent to a pitch distance between the cylinders by means of a work moving means 9. The direction of a plurality of cylinders arranged in the second row of a pair of cylinder rows is inclined based on the swing support table 4 by means of the work moving means 9 so that the direction is pointed to a machining direction. Thereafter, machining by the machining means 10 on at least one of a plurality of cylinders to form a second row is performed. |
