High-speed CNC engraving and milling machine malfunction how to deal with

If you have high speed CNC carving and milling machine surface adsorption, no suction vacuum pump does not turn or reverse, should refer to the following address: 1, electrical line voltage is normal; 2, whether the water circulation pump water little, motor is stuck living removed rust network fan rotation axis; 3, filter blocked in the vacuum pump clean; 4, mesa or pipe leak phenomenon dressing; 5, and positive &negative switching on the motor UVW any two lines to change the direction of motor. High-speed CNC engraving and milling machine is mostly choose vacuum adsorption fixed plate, such not only can be firmly fixed, not happen moving sculpture dislocation, etc. , and relatively fixed splint, can save the plank, carved into the plate edge.
