Abstract
PURPOSE:To improve the extent of productivity by constituting the clamp and unclamp of a spindle head to a drive unit so as to be performed in parallel with retreat and advance of the drive unit. CONSTITUTION:When a spindle head 30 is changed, first a drive unit 15 gets retreating from a machining zero position, and the spindle head 30 is engaged with a guide supporter 24, and when the engaging length is reached to a safety engaging range where it becomes more than the specified value, unclamp of a clamp device 40 is started, and unclamp of the spindle head 30 takes place in parallel with retreat of the drive unit 15. After the unclamp is over and the drive unit 15 has retreated to the specified changing position, a swivel body 23 is turned by an index device 20 and the so-far spindle head 30 is moved, and a new spindle head 30 is indexed in the front of the drive unit 15. Next, the clamp device 40 starts its clamp, and almost simultaneously advance of the drive unit 15 is started, and in parallel with this start, the new spindle head 30 is clamped. This clamp should be completed before the spindle head 30 comes off the safety engaging range.
