Maintenance Of High Precision CNC Lathe

- May 21, 2019-

High precision CNC lathe is a kind of high precision and high efficiency automatic machine tool.High precision CNC lathe has a wide range of processing properties, can be processed straight cylinder, oblique cylinder, arc and various threads.It has various compensation functions of linear interpolation and circular interpolation, and has played a good economic effect in the mass production of complex parts.

      High precision CNC lathe operators strictly abide by the operating procedures and daily maintenance system CNC lathe operators to strictly abide by the operating procedures and daily maintenance system, the quality of technical and professional operators is an important factor affecting the frequency of failure.When CNC lathe failure, the operator should pay attention to maintain the scene, and truthfully explain to the maintenance personnel before and after the failure, in order to facilitate the analysis, diagnosis of the cause of the fault, timely elimination.

      Prevent dust dirt from entering the internal in the CNC lathe CNC lathe processing workshops usually have oil mist in the air, dust, and even metal powder, once they fall in the CNC system in the circuit board or electronic device, easy to cause the insulation resistance between the components to drop, even cause the damage of components and circuit board, should check whether the CNC on the cooling fan is working normally.Every six months or every quarter to check whether there is a blockage of the air duct filter, if the dust accumulation on the filter network is too much, not timely cleaning, will cause the temperature inside the CNC cabinet is too high.

      In general, the CMOS RAM storage device is equipped with rechargeable battery maintenance circuit in the CNC system to ensure that the contents of its memory can be maintained during the period when the system is not energized.In general, the system should be replaced once a year, even if it has not failed, to ensure the normal operation of the system.Battery replacement should be carried out under the power supply state of the CNC system to prevent the loss of RAM information during replacement.

      When the spare printed circuit board is not used for a long time, it should be installed into the CNC system regularly and run for a period of time to prevent damage.

      Regularly adjust the tightness of the driving belt of the spindle of CNC lathe to prevent the loss of rotation caused by slipping of the belt;Check the constant temperature oil tank for spindle lubrication, adjust the temperature range, replenish oil quantity in time, and clean the filter;CNC lathe spindle tool clamping device for a long time after the use of clearance, impact tool clamping, need to adjust the displacement of hydraulic cylinder piston.Check and adjust the axial clearance of screw pair of CNC lathe screw on a regular basis to ensure reverse transmission accuracy and axial rigidity;Regularly check whether the connection between the screw of CNC lathe and the bed is loose;The screw protection device should be replaced in time if it is damaged to prevent dust or chips from entering.
