CNC router machine spindle motor fault often appear

Spindle motor is the basic guarantee of carving processing fine, because of the high precision, such as the axis of the cone accuracy within 0.002 mm, became the most vulnerable link in CNC router machine use.Can high speed spindle motor, drive tool to engraving, so prone to failure.Common faults are:
1. The electrical heating
Reason: 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. The noise is too large
Reason: it could be hit to the main shaft, or bearing local damage, or bearing normal wear.Method: the need to replace the bearing.
3. The tool card head, not down
Reason: knives, card head not according to the requirements in the nut, or the card head, or a nut has fault.Excluded methods: should use small tool to remove the card head, tapping the motor shaft, it is strictly prohibited to replace the nut after processing.
4. Partial drilling
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.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. The cutting tool is not straight
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.Excluded methods: head of the foreign body between the clear in time, according to the requirements to install card cutter, the handle into tool card head length must be > = 18 mm.Need to change in time card.
6. The motor spindle cone and card head is damaged
Reason: knives, 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. The cutting tool card head, not down
Reason: knives, card head not according to the requirements in the nut, or the card head, or a nut has fault.Excluded methods: should use small tool to remove the card head, tapping the motor shaft, it is strictly prohibited to replace the nut after processing.
8. Open the spindle speed spindle turn
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.Method: retightened connectors.To weld will take off the welding place, or change the connection cable.Use voltage regulator.http://www.morngraver.com
