Q & A

What is the primary purpose of the video?

The video aims to explain the components and functions of a lathe machine.

What are the dimensions of the small lathe machine described?

The small lathe machine is approximately 1 meter long and 30 to 40 cm wide.

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

The headstock contains controls for operating the machine, including speed adjustments, on/off buttons, and direction control for the spindle.

How is spindle speed adjusted on the lathe machine?

Spindle speed is adjusted using settings A1, A2, B1, B2, and B3, based on a speed chart, with speeds ranging from 175 RPM to 1820 RPM.

What safety precaution must be taken when adjusting the spindle's rotation direction?

The direction of the spindle's rotation should only be changed when the spindle is stationary to avoid accidents.

What does the tool post do in a lathe machine?

The tool post holds and secures cutting tools in place during machining operations.

What features does the tailstock provide?

The tailstock serves as a center point for the cutting tool, can hold a drill bit for creating holes, and provides support for longer workpieces to ensure stability.

How does the feed mechanism operate in the lathe?

The feed mechanism includes manual controls for moving the tool in various directions, with precise measurements for each movement and an automatic feed feature for lateral movement.

What is the maximum angle adjustment possible for creating angled cuts on the lathe?

The maximum angle adjustment for creating angled cuts is up to 45 degrees.

Why is it important to align the cutting tool and the center point in the lathe?

Proper alignment ensures smooth cutting and prevents issues such as uneven surfaces or rough finishes on the workpiece.
