PURPOSE:To make a moving mechanism and a moving space of a table unnecessary, and to make a device small-sized by moving a work along on a table fixed to a bed, and also moving a head along an arm overhanged to the upper side of the table. CONSTITUTION:A work W is held by a clamp pawl 6' of a clamper 6 provided on a saddle 5, on a table 4 fixed to a bed 1 of a device A. As for the saddle 5, an intermal thread a' in its inside is engaged to a ball screw S2, therefore, the ball screw S2 rotates by rotating a motor forward and backward, and the saddle fixed to the internal thread a' moves the work W in the left and right directions of the device A. Subsequently, when a plasma head 7 is moved along an arm 3 in the front and rear directions of the device A, the work W can reach a desired working point. Next, the work W is brought to plasma working along an optional curve by a plasma torch held by the plasma head 7. |
