What is lathe and milling machine?

Lathe Machine:

A lathe machine is a tool used to shape objects by rotating them against a cutting tool. The primary function of a lathe is to remove material from a workpiece to create a cylindrical or symmetrical shape. It is commonly used in metalworking, woodturning, and even glassworking.

- How it Works: The workpiece is clamped onto a spindle, which spins it while a stationary cutting tool is applied to the surface. By moving the cutting tool along the axis of rotation, you can shape the object.

- Main Operations:

 - Turning: Removing material to reduce the diameter of the workpiece.

 - Facing: Cutting across the end of the workpiece to make it flat.

 - Threading: Cutting helical grooves to create screws or bolts.

 - Boring: Enlarging an existing hole.

- Common Uses: Lathes are used to create cylindrical objects like shafts, screws, and pipes.

Milling Machine:

A milling machine is a tool used to remove material from a workpiece by feeding it against a rotating cutting tool. Unlike a lathe, which spins the workpiece, the cutting tool in a milling machine spins, and the workpiece remains stationary or moves along an axis.

- How it Works: A cutting tool with multiple sharp edges rotates at high speed, and the workpiece is moved along the X, Y, or Z axis to remove material and create the desired shape.

- Main Operations:

 - Face Milling: Cutting flat surfaces on the workpiece.

 - End Milling: Creating complex shapes like slots, pockets, or contours.

 - Drilling: Making holes by lowering the rotating tool into the workpiece.

 - Slotting: Cutting grooves or keyways in the workpiece.

- Common Uses: Milling machines are versatile and can be used to create a wide range of parts, such as gears, molds, and precision components.

Key Differences:

- Lathe: Rotates the workpiece, primarily used for cylindrical objects.

- Milling Machine: Rotates the cutting tool, used for a wider variety of shapes and complex geometries.

Both machines are crucial in manufacturing and machining industries for producing precise and intricate parts.
