What Are The Solutions To The Failure Of Large-scale CNC Gantry Milling?

Large-scale CNC gantry milling processing is a commonly used processing method for large-scale hardware. When performing large-scale CNC gantry milling processing, we must understand the safety production precautions of large-scale CNC gantry milling operators and the equipment characteristics of large-scale CNC gantry milling processing. To understand the solutions to some common faults in large-scale CNC gantry milling.

Common failure one: The processing surface is not flat at the tool connection.

Solution: Check the parallelism of the worktable, the parallelism of the main axis relative to the worktable, and the verticality of the lifting table relative to the worktable.

Common fault 2: The operating handle of the main shaft gearbox falls off automatically.

Solution: Replace the spring or add a gasket.

Common fault 3: The operating handle of the main shaft gearbox cannot be operated.

Solution:

1. The vertical shaft handle and the hole connection are stuck, remove and repair;

2. The sector gear and the clip are stuck, adjust the gap to about 0.15mm;

3. The shift fork shaft is bent and deformed and straightened;

4. The rack shaft deviates from the hole on the hole cover, changes the speed of other levels, moves the speed change plate, and adjusts the positioner spring.

Common fault 4: Abnormal machining accuracy

Solution:

1. Confirm that the feed unit of the large CNC gantry milling machine has not been changed;

2. Confirm that the zero offset of each axis is normal;

3. Confirm that the axial backlash is normal;

4. Confirm that the motor is running normally;

5. Confirm whether the parts such as screw, bearing, shaft coupling are normal.
