Precision machine tools to reduce what factors

2016-06-24 10:11:27
Causes abnormal processing accuracy faults concealed, diagnosis difficult, summarized the five main reasons:machine toolFeed unit has been altered or varied;machine toolZero offset of each axis abnormalities; axial backlash exception; Abnormal motor running, namely electrical and control part of the anomaly; mechanical failure, such as screws, bearings, couplings and other components. Also the establishment of processing, tool selection and human factors, may also lead to abnormal processing accuracy.
  First, the cause of abnormal processing accuracy failure.
    Causes abnormal processing accuracy faults concealed, diagnosis difficult, summarized the five main reasons: machine tool feed unit has been altered or varied; zero offset each machine axis abnormalities; axial backlash exception; Abnormal motor running, namely electrical and control part of the anomaly; mechanical failure, such as screws, bearings, couplings and other components. Also the establishment of processing, tool selection and human factors, may also lead to abnormal processing accuracy.
  two,CNC machine toolsFailure criteria.
  After the first External InternalCNC machine toolsIs a mechanical, hydraulic, electrical as one of the tools, so the failure occurred will be reflected by these three comprehensive. Maintenance personnel should be from outside to inside one by one investigation to avoid casually unsealed, disassemble, otherwise it will expand failure, so that the loss of precision machine tools and reduce performance.
  After the first electrical machinery in general, mechanical failure easier to find, and numerical control system failure diagnosis is more difficult. Before troubleshooting, first rule out mechanical failure, can often achieve a multiplier effect.
  After the first static and dynamic power to the machine at the stationary state, through understanding, observation, testing, analysis, confirmed after non-destructive fault, only to the machine is switched; in operating conditions, the dynamic observation, inspection and testing, troubleshooting. The destructive fault, you must first rule out the danger, before electricity.
  After briefly complicated when multiple failures are intertwined overshadowed when temporarily unable to start, should be easy to solve the problem after solving more difficult problems. After solving the problem often simple, the difficult problem may become easier.
