Abstract: The invention provides a machining apparatus, and its machining method, having machining tables whose weight do not increase so much even if a number of machining sections such as spindles is increased.

Abstract: A machine for perforating corrugated tubing at accurately spaced locations includes a double chain conveyor which positively engages the tubing and is driven intermittently to advance the tubing in steps of equal length. Upon completion of each step a pair of clamping members are actuated to engage the tubing, the clamping faces of the members being shaped so as to locate the tubing positively while it is stationary. When the tubing is so located, accurately positioned sets of cutters are brought into operation so as to cut slots or holes in the tubing at the desired locations. Upon completion of the cutting stroke, the clamping members are automatically released and the conveyor advances the tubing by another step. The sequence of operations in each cycle is controlled by limit switches responsive to the positions of the conveyor, the clamping means and the cutters. The cutters may be rotary saws or rotary drills.
