NC system maintenance

NC system maintenance

  1.Strictly abide by the rules and routine maintenance of the system

 2. Numerical control device to prevent dust from entering

  Floating dust and metal powder easily lead to decreased Cnc machining insulation resistance between    components, which failure or even damage to components.

     3. CNC cabinet cooling time cleaning the ventilation system

     4. Regular monitoring system of mains voltage NC

     Rated grid voltage in the range 85% to 110%.

     5. Periodic replacement of storage batteries

      6. When not in NC long-term maintenance of the system

 Often to the NC system power or to run the warm machine program CNC machine tools.

  7. Spare circuit board to maintain the maintenance of mechanical  Cnc machining  components  Maintenance of mechanical parts

    1. Tool and maintenance of mechanical hand tool change 

① Tool to manually upload tool, to ensure that equipment in place to check the reliability of the locking blade seat;

      ② strictly prohibited overweight, long knives into the knife, to prevent the robot tool change out a knife or cutting tool and workpiece, fixtures and other collision;

     ③ The Tool Selection should be noted that the order placed in the magazine on the tool order is correct. Other options should also take note of the way Cutter number for the tool is consistent with the required tools to prevent the wrong tool for the accident cause;    

  ④ keeping a clean tool holder and tool pocket;

 ⑤ always check the magazine's back to zero position is correct, check the spindle back to the tool change position is in place, and adjusting, or can not complete the tool change operation;    

  ⑥ boot, should be made and the mechanical hand tool storage space to run, check each part is working properly, especially the limit switch and solenoid valve can operate normally.     

 2. Maintenance of ball screw      

① periodic inspection, adjustment screw nut axial clearance, to ensure the accuracy and axial stiffness of the reverse drive;    

  ② periodically check the screw connections support and the bed is loose and the support bearings for damage. If these problems to tighten the loose parts in a timely manner, the replacement of support bearings;    

  ③ The grease of the ball screw, lead screw washed once every six months old on the oil, replace oil. The ball screw with lubricating oil, grease once a day before work machine;

      ④ hard to avoid dust or chips into the screw shields, and the work process crashing shields, protective devices should be replaced whenever damaged.

 3. Maintenance of the main drive chain

      ① adjusted periodically with the tightness of the spindle drive;

      ② to prevent all kinds of impurities into the fuel tank. Replaced once a year oil;

     ③ Connect the handle to keep the spindle area clean. The need for timely adjustment of the hydraulic cylinder and piston displacement;

     ④ To adjust the weight in time.   

  4. Hydraulic system maintenance      

    ① or replacement of oil filter on a regular basis; 

    ② control the temperature of the hydraulic system oil; 

    ③ to prevent leakage of hydraulic system;    

 ④ tank and pipe cleaning regularly checked;  

  ⑤ routine point inspection system.    

 5.  Cnc machining  Pneumatic system maintenance   

  ① remove air impurities and moisture;    

 ② Check the oil mist system, the fuel supply;  

   ③ to maintain the tightness of the system;    

 ④ attention to regulating the working pressure;

   ⑤ cleaning or replacement of pneumatic components, filters;
