Effective Strategies for Solving Chip Removaling Faults in Slant CNC Lathe

The advantage of slant bed CNC lathes lies in their efficient chip removal, significantly improving productivity and surface quality. However, in actual machining, problems such as poor chip removal and chip buildup blockage can still occur, affecting equipment stability and production efficiency. This article focuses on the diagnosis, daily maintenance, and troubleshooting of chip removal problems during use, helping you quickly locate and resolve issues.

I. Priority of Fault Diagnosis

Abnormal chip removal system function is the core issue and should be prioritized for investigation and calibration. Common causes include loose chip removal chain, deformed scraper, abnormal motor speed, improper chip removal port height, guide plate misalignment, and piping sealing problems in the negative pressure chip removal system.

Mismatch between machining process and chip morphology can exacerbate chip removal problems, such as excessively high or low turning parameters and improper coolant spraying.

Lack of daily maintenance can easily lead to aging and blockage; it should be included in routine inspections and maintenance.

II. Key Points for On-Site Investigation and Handling

· Mechanical Transmission and Positioning

Check the tension of the chip removal chain; if loose, adjust the tensioning device.

If the scraper is deformed, replace it with a new one according to specifications.

· Power and Control

Calibrate the motor speed of the chip removal to ensure it matches the amount of chips generated, avoiding insufficient power.

· Conveying Channel

Adjust the height of the chip discharge port according to the chip morphology (ribbon, granular) to ensure the guide plate fits snugly against the inclined surface of the CNC machine bed, reducing buildup at corners.

· Chip and Process Matching

Adjust cutting parameters according to the material (steel, aluminum, cast iron) to control the chips to be short, coiled, or granular, reducing the risk of entanglement and blockage.

Adjust the coolant nozzle angle and flow rate to ensure effective flushing of the chipping area.

· System Sealing and Negative Pressure

Check the sealing of the chip removal pipeline to ensure the negative pressure chip conveying system is working properly. Repair any leaks promptly.

III. Daily Maintenance and Care Points

· Daily: After processing, clean the residual chips inside the chip removal and check the wear of the scraper and chain.

· Weekly: Disassemble the chip removal pipeline, clean the chips and oil adhering to the inner wall, and check the sealing of the interfaces.

• Monthly: Lubrication and maintenance of the chip removal motor and transmission components to ensure long-term stable operation.

· Maintenance Records: Establish an inspection record form for the chip conveying system, recording problems found, handling measures, and information on replaced parts for traceability and improvement.

IV. Troubleshooting Process

• Initial On-Site Diagnosis: Prioritize addressing any malfunctions in the chip conveying system.

• Item-by-Item Check: Inspect the CNC turning center chain tension, scraper, motor speed, chip outlet height, guide plate, pipeline seals, and chip morphology in sequence.

• Implement Modifications and Testing: After replacement or adjustment, conduct a short test run to confirm smooth chip conveying.

• Recording and Feedback: Record the handling process, replacement part numbers, and results. For further upgrades, contact technical support.

FAQ

Why is the chip removal always clogged?

This may be due to a loose chain, deformed scraper, unsuitable chip outlet height, or insufficient negative pressure. Please check and repair step by step in sequence.

How to quickly determine if the scraper needs replacement?

Replace the scraper if it shows obvious deformation, wear, or cracks, and check the chain condition at the same time.

How to improve chip removal efficiency?

Optimize chip morphology (short curl/granular), adjust nozzle angle and flow rate, and ensure the pipeline is properly sealed.
