PURPOSE:To obtain an injection type working machine capable of working a round hole small in diameter speedily and accurately by using such a structure that a member supporting a working means small in inertia, etc., is worked by rotation and drive in working a small size piece. CONSTITUTION:When the round hole 59 having a radius RI is made by a laser beam machine 1 on a work 57, the work 57 is put on the mounting surface 3b of a table 3, then, a work starting command is outputted to a main controlling part 41. The main control part 41 reads a working program PRG regarding the work 47 from a memory 46 and respectively moves and drives through an axial control part 50 the table 3 in the directions of arrows A, B, a saddle 9 in the directions of arrows C, D, further, a head 12 in the directions of arrows E, F to work the work 57. In the meanwhile, since a working torch 26 moves in the direction of an axis C while it rotates, the round hole can be worked more accurately than in the linear approximate working by the control of double axes X and Y. |
