A detailed Lathe DAILY preventive maintenance Inspection checklist
1. General Inspection
2. Lubrication
3. Electrical System
4. Spindle and Tooling
5. Alignment and Calibration
- Use a precision level to check the lathe bed.
- Adjust leveling feet as needed to achieve level.
- Recheck with the level after adjustments.
- Ensure the machine is stable and secure.
- Use a test bar between tailstock and headstock.
- Measure the gap at both ends of the test bar.
- Adjust tailstock if misalignment exceeds specifications.
- Recheck alignment after adjustments are made.
- Use standard calibration tools for each device.
- Check zero settings and adjust as necessary.
- Document any deviations and recalibrate if needed.
- Confirm calibration is within acceptable tolerances.

- Adjust chuck mounting if misalignment is detected.
- Recheck runout after adjustments are made.
- Use a square to check the tool post alignment.
- Adjust tool post as necessary to achieve perpendicularity.
- Tighten all fastening screws after adjustments.
- Verify alignment with a test cut if necessary.
- Go through each adjustment point and check tightness.
- Use a torque wrench for critical fasteners.
- Ensure no screws are left loose that could affect operation.
- Document any adjustments made for future reference.
- Create a dedicated section for alignment records.
- Include dates, measurements, and technician's name.
- Note any adjustments made and their impact.
