<p>PROBLEM TO BE SOLVED: To provide a cutting method and it's apparatus which condenses laser beams split from one laser oscillator by simple means, to the two points on a work for cutting. SOLUTION: A laser torch, having two focus lens which condensates laser beams pulsated from the laser oscillator to two one-pitch removed points on a work, cuts the work which moves in X-Y direction in a plane, rotating around it's axis-line.</p> |
