Description

After positioning, probe head 23 is moved above mounting plate 6 under the drive of probe motor 52 to avoid damaging the probe during cutting. At the same time, the cutting motor 31 drives the cutting back plate 25 to slide, and the cutting back plate 25 drives the cutting head 24 to move downward to perform the cutting work. After the cutting is completed, the cutting head 24 moves upward to a suitable position to avoid the workpiece from hitting the cutting head 24 due to rotation. Then the first servo motor 141 and the second servo motor 142 on both sides drive the workpiece to rotate by a specified angle. After that, the probe is moved downward again to perform edge finding and positioning. After positioning is completed, the probe rises and the cutting head 24 cuts downward. After the workpiece is cut, the hollow rotating platform 113 drives the rotating table to exchange the position of one of the two sets of support groups 13 with the original support group 13 located in the cutting area, and repeats the above positioning and cutting action. After all the workpieces on both sides are cut, the rotating pressing motor is controlled to release the workpiece and replace the profile to be cut.
