This manual provides a comprehensive guide to maintaining a compact lathe, covering essential tasks, tools, and best practices.

1. Understanding the Components of a Compact Lathe

Before diving into maintenance, it is important to understand the components of a compact lathe. These include:

- Lathe Spindle: The central axis upon which the workpiece is clamped and rotated.

- Lathe Bed: The base of the machine, providing support and stability.

- Headstock: Contains the driving mechanism and the workpiece spindle.

- Tailstock: Supports the end of the workpiece and provides a surface for the tool to be mounted.

- Tool Rest: A component that holds and supports cutting tools.

- Hand Wheels and Controls: Used to operate the lathe safely and efficiently.

- Coolant System: Facilitates chip removal and reduces heat generation.

- Electrical System: Provides power to the motor and controls.

Understanding these components helps in identifying where to start with maintenance.
