A pair of centering spindles are disposed away from cutting spindles and movably in the direction of Z or parallel with the axial center line of cutting spindles. A plurality of log center detecting means are disposed along the Z direction in relative to a log chucked by the centering spindles. A pair of holding members are mounted movably in the directions of X, Z, and Y including components orthogonally intersecting the X and Z. By way of controlling means, the centering spindle holding a log is caused to rotate at least one revolution thereby enabling the log center detecting means to determine each position of axial center which is assumed to constitute the axial centers at both end faces of the log, the virtual line passing through every positions of axial centers in Z direction is aligned with the Y, and the holding members are moved in the Z direction to hold the log, after which the chucking of log by the centering spindles are released. The holding members are moved in the X direction toward the cutting spindle, as well as in the Y direction to align every axial centers with the rotational center of cutting spindles, thus allowing the log to be chucked by the cutting spindle.
