Why is the cutting section of CNC flame cutting machine rough

- Jun 25, 2019-

The amount of dragging after cutting the section is too large

Phenomenon: The cut section of the cutting section is greatly offset backward, and at the same time, different degrees of depression occur with the magnitude of the offset.

Reason:

1. The cutting speed is too fast;

2. The cutting nozzle used is too small, the cutting oxygen flow rate is too small, the cutting oxygen pressure is too low;

3. The height of the cutting nozzle and the workpiece is too large.

4. Near the lower edge of the cutting section, the amount of cutting is too large

Phenomenon: The amount of cutting advance is too large near the lower edge of the cutting section.

Reasons: 1. The cutting nozzle is blocked or damaged, and the wind line is blocked and deteriorated. 5. The cutting torch is not vertical or the cutting nozzle has a problem, so that the wind line is not correct or inclined.

6. In the upper part of the cutting section, there is a cutting amount of advance

Phenomenon: A certain degree of cutting advance is formed near the upper edge.

Reasons:

1. The torch is not perpendicular to the cutting direction, the cutting nozzle is blocked or damaged;

2. The wind wire is blocked and deteriorated;
