(One) the requirement of numerical control machine tool to operating maintenance technician
Numerical control machine tool uses the computer to control, drive system has taller technical complexity, the precision demand of mechanical part is higher also. Accordingly, the operation of machine tool of demand numerical control, maintenance and administrator have higher culture level and integrated technology quality.
The treatment of numerical control machine tool has according to the program, program of manual work out can be used when spare parts appearance is simple. When spare parts form is more complex, process designing workload is big, manual process designing is more difficult and often easy make mistake, because this must collect maneuver,consider machine automatic process designing. So, the operation personnel of numerical control machine tool operates experience besides what should have certain technology knowledge and general accuracy machine tool besides, still answer principle of the structural characteristic of numerical control machine tool, job to understand very much, have the capacity that operates the computer adroitly, must undertake grooming technically in to program respect, assess the machine on eligible ability to operate.
Correct maintenance and effective maintenance also are one of machine tool of use numerical control serious problem. The maintenance technician of numerical control machine tool is due taller academic knowledge and maintenance technology, should know the rigid structure of numerical control machine tool, know the electric principle of numerical control machine tool and electronic circuit, due still knowledge of major of wider machine, report, gas, fluid, such ability integration analysis, judge the germ of breakdown, undertake correctly maintaining, the favorable moving situation that assures numerical control machine tool. Accordingly, maintenance technician of numerical control machine tool and operation personnel are same, must undertake grooming technically.
(2) the requirement of numerical control machine tool to clamping apparatus and cutting tool
Numerical control machine tool is simpler to the requirement of clamping apparatus, odd general clamping apparatus is used commonly when production. When batch is produced, to save treatment man-hour, should use special fixture. The clamping apparatus of numerical control machine tool should locate reliable, but automatic clamp or loose workpiece. Clamping apparatus still should have good platoon bit, cooling property.
The cutting tool of numerical control machine tool should have the following characteristic:
(1) have taller precision, durability, geometrical dimension stability, change is little.
(2) cutting tool can mediate beforehand outside implementation machine change a knife quickly, treatment wants to determine its size via trying cutting when high accuracy aperture.
(3) the regulation that the petiole of cutting tool should satisfy petiole standard.
(4) control those who cut bits to break off well with eduction.
(5) have good can cool function.
