The problems often CNCN engraving machine spindle motor

The spindle motor is the basic guarantee of carving processing fine, because of the high precision, such as the axis of the cone precision in 0. Less than 002 mm, became the most vulnerable link in CNC engraving machine use. Can high speed spindle motor, drive tool to engraving, so prone to failure. The common faults are:
( 1) Electrical heating
reasons: improper processing methods, such as low speed selection, turning too much; Antifreezing fluid temperature is too high, influence motor cooling; Water pump failure, there are foreign bodies blocked, leading to poor circulation.
elimination method: choose a reasonable method for processing, often replace the antifreeze, often a foreign body in clear water tank and water pump, water flow.
　　（ 2) Loud noises
the reason: it could be hit to the main shaft, or bearing local damage, or bearing normal wear.
elimination method: need to replace the bearing.
　　（ 3) Tool card head not down
the reason: the knife, the card head not according to the requirements in the nut, or the card head, or a nut has fault.
elimination method: should use small tool to remove the card head, it is strictly prohibited to knock the motor shaft, after processing to replace the nut.
　　（ 4) Slant borehole
reason: knives card is not straight, beating; Tool clamping is not tight, move inside the card head string; Blade is not in the center of a circle or drill head has wear; Into the workpiece speed through high; Cutting tool exposed portion is too long; Bearing wear loss of accuracy, causing shaft system.
elimination method: according to the requirements to install card cutter, bit change, reduce the drilling speed, short blade drill, reduce the cutter length exposed portion.
　　（ 5) Tool pack not
the reason: card head, nut and clean up the debris inside the motor shaft head was not; No loading card tool as required; The handle into tool card head length is too short, clamping rickety; Card head use time is too long wear loss of accuracy.
elimination method: clear in time the head of the foreign body, reload card cutter according to the requirement, and the handle into tool card head length must & gt; =18mm。 Need to change in time card.
　　（ 6) Motor spindle cone and card head damaged
the reason: the knife, card head not according to the requirements in the nut, or the card head, or a nut has fault, the improper handling damage.
elimination method: change the motor, the replacement card head, replace the nut, according to the rules on the knife.
　　（ 7) Tool card head not down
the reason: the knife, the card head not according to the requirements in the nut, or the card head, or a nut has fault.
elimination method: should use small tool to remove the card head, it is strictly prohibited to knock the motor shaft, after processing to replace the nut.
　　（ 8) Open the spindle speed spindle turn not
reason: check the spindle cable connectors are reliable; Check the shaft connecting the normal conduction, do you have any disconnection, sealing off; Check whether the voltage is too low.
elimination method: retightened connectors. To weld will take off the welding place, or change the connection cable. Use voltage regulator.
