What causes CNC plasma cutting machine cutting precision
CNC cutting machine in the field of industry has an important significance, CNC plasma cutting machine is a kind of CNC equipment, in the CNC plasma cutting machine operation application, there will be the phenomenon of the precision size of the work parts is not allowed, what factors lead to it?
A, programming software errors lead to, in the operation of CNC plasma cutting machine, will accidentally appear some mistakes, such as some numbers accidentally pressed wrong, and then did not correct the function, will produce CNC code size problems, line segments many times there is a large error, the formation of entry point introduction and lead out of the phenomenon of misalming, will also cause the whole board set of material time work part spacing deviation.
B, CNC plasma cutting machine's own accuracy problems lead to the main accuracy of machinery is based on parallelity and horizontality to master, cutting platform level also affects the accuracy of the work piece. General idea accuracy is affected by the CNC system and motion control card, especially the pulse, which will cause the cutting circle to produce not round, and then the size of the large part does not conform to the standard of the status quo.
C, CNC plasma cutting machine cutting mouth quality problems lead to, to pay attention to the quality of the general cut mouth will affect the surface quality of the work piece and cutting side of the straightness, cutting degree must be the cutting platform is consistent, otherwise it will also affect its size is not equal to the phenomenon.
D, CNC plasma cutting machine cutting parts deformation caused, programming with a reasonable lead position and cutting direction can reduce deformation, we can add some cooling devices as needed, can fix its model, so as to prevent their deformation. Stress in the material will be released and redloced with the removal of the material, causing the plate displacement and deformation.
E, CNC plasma cutting machine operation, staff running back and forth, regular running to check through simulation whether there is a program problem, if the program is not a problem to check the system software (including the built-in software of the shaft card) problems, data cable loose caused the system and servo control line contact is bad, servo feedback signal loss so we all in the operation if there is a size problem, we can do in this regard.
F, CNC plasma cutting machine operation in the increase or decrease of gas flow caused, so if the gas flow is too large, will make the arc column shorter, loss of heat increase, so that the cutting capacity is reduced, resulting in size errors.
G, CNC plasma cutting electromechanical electrode internal shrinking results in a suitable distance can make the arc in the cut mouth to get good compression, to obtain energy concentration, high temperature plasma arc and effective cutting. Too large or too small, will make the electrode serious burn damage, cut mouth burn and cutting capacity decreased, the general internal shrinkage can not exceed 8-11mm.
