Study Notes
Centre or Engine Lathe
- A centre or engine lathe has several basic parts, enabling it to perform various machining operations.
- The main function of a centre or engine lathe is to machine symmetric parts, such as axles, shafts, and cylinders, by rotating the workpiece against a fixed cutting tool.
Types of Lathes
- A speed lathe is used for machining soft materials.
- A bench lathe is mounted on a bench and is suitable for small-scale work.
- A tool room lathe is designed for precision work and is used for working on different ranges of speeds and highly precious work.
- A centre lathe can be adjusted to adapt to different workpiece lengths.
Functional Components
- The spindle drives the lathe at different speeds in a centre or engine lathe.
- A tool room lathe typically consists of a bed, headstock, tailstock, and carriage.
- The tailstock is used to support the workpiece during machining operations.
Operations and Attachments
- With suitable attachments, a lathe can perform various operations, including turning, facing, and drilling.
- Work-holding attachments, such as chucks and collets, can be held in the spindle of a lathe.
- During cutting operations, the cutting tool is fed manually or automatically, depending on the type of lathe and operation.
Centre Lathe Characteristics
- A centre lathe is designed for precision work and is characterized by its versatility and adaptability.
- The main function of a centre lathe is to machine symmetric parts, such as axles, shafts, and cylinders.
