ESSENTIAL OXYCUTTING
B-7
7 - RISK OF HEATING
When the machine cuts pieces:
- that are small (e.g. where one dimension is less than 100 mm),
- nested closely,
- with several torches set close to each other (e.g. 150 - 500 mm)
The sheet temperature may rise (above 300°C for instance). As a
result, the mechanical systems located near and above the
oxycutting nozzles may be exposed to high temperatures and be
damaged rapidly (components, pipes, wires).
Heating of parts also disrupts sensing, and thus adversely affects the cutting quality.
THE SOLUTION MAY CONSIST IN :
- modifying the cutting program to distance the succession of cuts while cutting the pieces,
- and/or using a cutting table with fume extraction so as to carry away as many calories as possible from the bottom
of the sheet (so as to avoid the rise of calories above the sheet).
If these measures do not deliver the expected result, the customer should ask for assistance from the
manufacturer.
