CNC flame cutter section roughness defect reason
1. Cutting section after the amount of drag is too large
Phenomenon: The cutting section cut is offset backward sharply, and with the size of the offset, there are different degrees of dents.
Reason: 1. Cutting speed is too fast 2. The cut mouth used is too small, the cutting oxygen flow is too small, the cutting oxygen pressure is too low 3. the height of the cutting mouth and the workpiece is too large.
2. Close to the lower edge of the cutting section, cutting ahead too much
Phenomenon: The cutting is too large at the edge near the lower edge of the cutting section.
Reason: 1. Cut mouth blocked or damaged, the wind line is blocked to become bad 2. The torch is not vertical or the cut mouth has problems, so that the wind line is not correct, tilt.
3. In the upper part of the cutting section, the appearance of cutting ahead of the amount
Phenomenon: At the upper edge, a certain degree of cutting ahead is formed.
Reason: The torch is not perpendicular to the cutting direction, the nozzle is blocked or damaged.
