5. Electric Control System
E. Superiority of Control Technique in Wuxi JACK CNC-CP5-1400/L 5 Axis CNC Pipe Thermal Gas Cutting Machine:
1. At the early stage of CNC Pipe Cutting Machine, 5 Axis was the high end version for Φ1400mm diameter pipe;
2. At that time, the impetus on exploiting 5 Axis control for the purpose of chamfering and beveling is, this machine is for making prepare for next step of welding and or assembly, in corresponding Welding Roller Bed. So, the ability of beveling the critical performance index, for any set of machine on pipe cutting;
3. For those pipes with thick wall, without groove of kerf (3 Axis model machine can not attain this target), it will be difficult to have accurate assemble under the condition of oblique intersection of pipe;
4. The reason is, in CNC Pipe Intersection Cutting Machine, programming is done on the basis of external diameter of pipe. So, the wall thickness multiply with cos of oblique angle of pipe, the result will be bigger or smaller than the accurate result, which causes difficulty on later on assembly;
5. For this 5 Axis configuration CNC machine, the difficulty mainly lies in precision and stability of kerf cutting unit, which calls for sophisticated technology;
6. Recent years sees burgeoning on technique of CNC control pipe cutting, and the 5 Axis CNC version is the mainstream, which has advantages of best cost effectiveness, delivering stable and good quality performance from machine nowadays.
