When cutting machine in cutting carbon steel common problems and solutions
by：ZORON Machinery
2021-01-29
Appear, cutting carbon steel, machined part burr
general mechanical parts appear burr, the possible reasons include:
( 1) Focal shift, focus location tests, adjustments according to the offset of focus.
( 2) The output power is not enough, need to check whether the generator working normally, if the normal, is to observe the control button on the output value is correct, if not correct.
( 3) Cutting speed is too slow, to increase the linear velocity when operating control
( 4) Cutting gas purity is not enough, the need to provide high quality gas cutting work.
( 5) Machine tool operation instability time is too long, need to shutdown restart at this time.
( 6) Adjusting the process parameters.
( 7) To check whether there is a dirty lenses in the process of transmission, or whether the lens is dirty, whether the lens with the naked eye is not easy to find the tiny cracks, these will affect the transmission.
2, not completely cutting
the reasons for not completely cutting:
( 1) Nozzle selection and processing of the thickness of the plate do not match, replace the nozzle or processing board.
( 2) Reduce the linear velocity of the cutting speed is too fast, need operating controls.
3, mild steel cutting occurs when abnormal spark
normal cutting low carbon steel, fire flower long, flat, open fork is less. Appear abnormal spark will affect the smoothness of the cutting section of machined part and machining quality. At this point in the case of other parameters is normal, should consider the following:
( 1) Nozzle head nozzle loss serious, should be timely replacement.
( 2) Under the condition of without a new nozzle replacement, gas pressure should increase the cutting work.
( 3) If the nozzle head joint thread and loose, should immediately stop cutting, check the connection status, again for thread.
