Maintenance Guide for Swiss-Type Lathes During Hot And Rainy Seasons

I. Daily Maintenance

Before Daily Startup:

• Check equipment exterior for obvious signs of water stains or rust.

• Check the operational status of the electrical control cabinet's air conditioner/dehumidifier and the color of the desiccant.

• Check cutting fluid concentration, color, odor, and fluid level.

• Check lubricant levels and lubricating system pressure for normalcy.

• Check for foreign objects or accumulated fluid inside the guide rail and lead screw protective covers.

• Briefly jog the spindle and all axes, listening for abnormal noises.

During Operation:

• Closely monitor equipment temperatures (spindle, drive module, electrical cabinet temperature displays).

• Carefully observe the state of the cutting fluid (foam, unusual odor).

• Listen for normal operating sounds of the equipment.

After Shutdown:

• Thoroughly clean chips and cutting fluid from the work area, turret, guide bushing, spindle nose, tailstock, etc.

• Perform anti-rust treatment on critical components (wipe with anti-rust oil).

• Securely cover the equipment protective covers.

• Ensure the cutting fluid circulation pump is running (or follows the scheduled shutdown circulation procedure).

II. Standard Operating Procedures

• Avoid Sudden Temperature Changes: After prolonged shutdown (e.g., weekends) or during significant ambient temperature fluctuations, power on the equipment for a warm-up period of at least 30 minutes (to stabilize electrical component temperature and dissipate moisture) before running programs.

• Anti-Condensation Measures: When the workshop ambient temperature is lower than the internal temperature of the equipment (e.g., at night when AC is off, or early morning), condensation readily forms on surfaces and internally. Critical Action: Activate the electrical cabinet heater or dehumidifier before powering down or immediately after powering on (during the warm-up phase). Avoid directly activating cooling systems (e.g., spindle cooling, cutting fluid cooling) during significant temperature differentials.

• Address Anomalies Promptly: Immediately stop operation and investigate any abnormalities (overheating, overload, lubrication anomaly, pneumatic/hydraulic pressure anomaly). The equipment must never be operated with known faults.

III. Summary: Key Point Checklist

• Constant Temperature & Humidity is Core: Precision air conditioning + powerful dehumidification + strict monitoring.

• Cutting Fluid is Critical: Increase concentration, control temperature, clean frequently, enhance biocide treatment, replace regularly.

• Lubricating Greases Must Be Heat-Resistant: Replace with summer-specific high-viscosity-index greases; increase lubrication frequency/volume.

• Electrical Moisture Protection is Vital: Electrical cabinet sealing, effective AC/dehumidifier, clean and dry interior, waterproof connectors.

• Rust Prevention Requires Diligence: Wipe critical parts daily with specialized anti-rust agents.

• Increase Inspection Frequency: Temperature/humidity, fluid levels, concentration, oil quality, seals, abnormal noises/signs.

• Standard Operations Mitigate Risk: Sufficient warm-up, anti-condensation measures, prompt anomaly handling.

• Contingency Plans Must Be Ready: Prepare for heavy rain, prepare for power outages, conduct thorough post-rain inspections.

Strict implementation of the above maintenance measures will significantly reduce the failure rate of Swiss-type lathe production lines during hot and rainy seasons, safeguarding machining accuracy, extending equipment lifespan, and ensuring production safety. Maintenance records must be detailed to facilitate traceability, analysis, and continuous improvement. As specific conditions vary by factory, it is recommended to develop more granular inspection checklists and maintenance schedules by referencing the equipment manufacturer's manual and your own experience.
