Troubleshooting the Feeder of CNC Bar-Feeding Machines can be addressed through the following steps:
I. Troubleshooting
• Inspect the pressure plate: Verify whether the pressure plate applies force evenly. If uneven, adjust the pressure of the release mechanism.
Check the pneumatic system: If the feeding mechanism uses pneumatic release, verify that the air compressor pressure is normal.
Check the material rack and feeder: Ensure the coil fed from the rack aligns horizontally with the feeder and die.
Check the leveler-feeder compatibility: Confirm the leveler is compatible with the NC feeder, or verify the distance between leveler and feeder, material arc height, and press speed are appropriate.
Check the belt and material: Tighten the belt appropriately. Verify the coil's length, width, and thickness meet specifications.
Check the die and feed direction: Confirm the locating pins inside the die are functioning correctly. Check for any deviation in the feed direction. Verify the working direction and die are in proper condition.
Check the eccentric shaft and release shaft: If the eccentric shaft or release shaft seizes due to oil loss, clean with machine oil and apply grease.
II. Specific Troubleshooting
Stepper Motor Failure: If the stepper motor vibrates without rotating after program startup, check the connection plug for good contact. If contact is good, replace with a single-phase motor for testing. If still non-functional, inspect the high-power transistors and protection components (release diodes) on the driver board.
Mechanical or Control System Failure: During program execution, if the worktable suddenly stops while the stepper motor vibrates, attempt to return to origin and restart the process. If the worktable consistently halts at specific positions, inspect transmission components for damage, deformation, or foreign object blockage.
Tool Overrun During Home Return: If the tool overruns during home return at the end of a program operation, check for excessive mechanical resistance in the transmission system. Inspect for metal shavings or foreign objects in the stepper motor gearbox or on the transmission gears between the stepper motor and lead screw.
III. Preventive Measures
Regular Maintenance: Perform routine cleaning and lubrication of the CNC lathe feeder to maintain optimal equipment condition.
Operator Training: Provide specialized training for operators to ensure familiarity with equipment operation procedures and troubleshooting methods.
Use Premium Materials: Ensure high-quality materials meeting equipment specifications are used to prevent failures caused by material issues.
