Study Notes
Safety Precautions
- Wear appropriate safety gear, including eye protection and hearing protection.
- Keep the work area well-lit and clutter-free.
- Familiarize yourself with emergency stop procedures.
Lathe Components
- Bed: main component of the lathe.
- Headstock: houses the motor and spindle.
- Tailstock: supports longer workpieces.
- Tool rest: holds the cutting tool.
- Motor: powers the lathe.
Mounting Workpiece
- Secure the workpiece between the headstock and tailstock.
- Use the tailstock to support longer workpieces.
Lathe Operation
- Adjust the speed according to the material and project.
- Use the correct turning technique for the project.
Turning Techniques
- Spindle turning: turning a workpiece mounted between centers.
- Faceplate turning: turning a workpiece mounted on a faceplate.
- Bowl turning: turning a workpiece mounted on a faceplate, with the grain running perpendicular to the axis.
Maintenance and Lubrication
- Regularly clean and oil moving parts.
- Check belts, bearings, and pulleys for wear.
- Keep the lathe bed level and free from debris.
Troubleshooting
- Excessive vibration: check workpiece balance, lathe surface, and drive belt wear.
- Rough surface finish: check tool sharpness, lathe speed, and feed rate.
- Motor stall: reduce depth of cut, ensure proper voltage, and check belts and pulleys.
- Tailstock won't lock: clean quill and spindle, adjust locking mechanism, and lubricate moving parts.
