Abstract

PURPOSE:To aim at shortening the time required for machining, by shifting plural spindles in the axial direction, while making a pitch between these spindles adjustable. CONSTITUTION:Plural spindles S1 and S2 being insertedly coupled with each of plural tools on a pallet P, while a device shifting these spindles S1 and S2 in the spindle axial direction and insetting these tools on the pallet P in each spindle and devices 19 and 20 adjusting a pitch between shafts of these spindles S1 and S2 are installed. Therefore, plural work holes are machined at the same time whereby machining time can be shortened and, what is more, making it easily conformable to a variation in a pitch between spindles attendant upon pallet change.
