Lathe Machine Parts in Hindi

Summary

This video provides an in-depth explanation of the key components of a lathe machine. The presenter covers essential parts like the headstock, four-jaw chuck, tailstock, guideways, carriage, and tool post. It also discusses the functionality of the dead and live centers, the lead screw for precise movements, and the role of the bed and legs in supporting the machine. Additionally, practical features like the lamp for nighttime work and lubrication system are highlighted. The content is aimed at those interested in machine operations, such as SSC candidates preparing for technical roles.

Takeaways

• 😀 The headstock is the main body of the lathe and contains gears to control the speed of rotation, essential for adjusting workpiece movement.
• 😀 The chuck is a clamping device used to securely hold the workpiece. The 4-jaw chuck provides precise holding of round bars.
• 😀 The tailstock is opposite the headstock and provides additional support for the workpiece. It can hold tools such as drills.
• 😀 The tailstock includes two types of centers: the dead center (fixed, does not rotate) and the live center (rotating).
• 😀 The carriage is responsible for moving the tool post along the bed and controls the tool’s movement across the lathe.
• 😀 The cross slide allows for left-to-right movement of the tool during operations, giving precise control over tool positioning.
• 😀 The lead screw controls the automatic movement of the carriage during cutting, and its direction can be set to forward or reverse.
• 😀 The bed of the lathe is the foundational part, made from cast iron, providing a stable base and ensuring accuracy during machining.
• 😀 The lathe machine is supported by heavy legs that stabilize the machine, reducing vibrations during operation.
• 😀 The lathe includes a chip tray to collect debris and a lamp for better visibility during work, especially in low-light conditions.

Q & A

What is the purpose of the headstock in a lathe machine?

The headstock holds and drives the spindle, and houses gears that control the movement and speed of the machine. It is essential for controlling the rotation of the workpiece.

What is the function of the four-jaw chuck in a lathe machine?

The four-jaw chuck is used to securely grip the workpiece. It allows for accurate clamping of round bars or irregularly shaped objects, providing stability during turning operations.

What is the difference between a dead center and a live center?

A dead center is stationary and only provides support to the workpiece, while a live center rotates with the workpiece, allowing it to spin freely and handle axial loads more efficiently.

How does the tailstock function in a lathe machine?

The tailstock provides support to the workpiece, typically used in conjunction with a live center to hold the opposite end of the workpiece. It also facilitates additional operations like drilling.

What is the purpose of the carriage in a lathe machine?

The carriage moves the cutting tool along the workpiece. It holds various components like the tool post and cross-slide, allowing for precise control over the tool's movement during machining.

What is a cross-slide in a lathe machine?

The cross-slide is a part of the carriage that moves horizontally, enabling the cutting tool to approach the workpiece at different angles. It plays a critical role in transverse cutting operations.

What is a compound rest in a lathe machine?

A compound rest allows for precise angular adjustments of the cutting tool. It is mounted on the carriage and supports the tool post, enabling the tool to be tilted for different cutting angles.

What is the function of the lead screw in a lathe machine?

The lead screw controls the longitudinal movement of the carriage and cutting tool. It is used for fine adjustments during operations like threading and turning.

Why is the bed of the lathe machine important?

The bed provides a stable base for all the machine's components, such as the headstock, tailstock, and carriage. It is typically made from cast iron for strength and durability.

What role do the legs of the lathe machine play?

The legs support the bed and the entire machine structure, ensuring stability and minimizing vibration during operations, which is crucial for achieving precise machining results.
