CNC Drill Milling Machines Common Failures and Solution Inventory

Common failure one: Start the main motor does not turn.

Fault analysis:

1. The total power switch is not switched on;

2. The start button is not in good contact;

3. Contactordoes do not pick up, the main motor junction box and the wiring in the electrical disk contact is not good or the connector comes off.

Solution: Turn on the main power switch, check the start button connector, check the contactpoints in the electrical cabinet: check the wiring where the motor is connected.

Common fault two: spindle and outer surface oil leakage.

Fault analysis:

The oil in the mailbox is filled with too much and leaks from the top of the housing.

Solution: Do not allow the amount of oil to exceed the mark in the center of the oil label when filling oil.

Common fault three: spindle box clampis is not tight.

Fault analysis:

1. The 55-degree rail surface combined with the rocker arm combined with the rocker arm has a large gap;

2. The clamping block position of the spindle box is not correct;

3. Clamping the cylinder and brake frame joint oil leakage or related oil leakage;

4. The diamond block is not sufficiently excessive, can not make it stand up and self-locking.

Solution: 1. Adjust the screw so that the 55-degree rail surface should be more than 0.04mm clearance (checked with a 0.04mm stopper) in the release state, loosen the screw adjustment clamped to the appropriate position and tighten the screw.
