What are milling machines and lathes, and what is the difference between them?

1. What is a lathe?
Lathes create cylindrical parts by spinning material on a stationary tool.
Making parts using a lathe is called turning.
2. What is a milling machine?
Unlike a lathe, a milling machine holds the material in a jig and cuts it with a rotating tool.
3. The difference between the two.
(1) Different structures.
The lathe is a workpiece rotating tool with a fixed longitudinal and transverse movement to process circles and surfaces. The milling machine fixes the blank and clamps the parts on the machine tool spindle through a three-grip chuck.
(2) Different operating methods.
Lathes move parts around an axis and tools around an axis, while milling machines fix workpieces and process parts by moving fixtures and milling cutters.
(3) Different processing objects.
Lathes can be used to process various rotary forming surfaces, such as internal and external cylindrical surfaces, internal and external conical surfaces, internal and external threads, end faces, grooves, knurling, etc.
The milling machine can process planes (horizontal planes, vertical planes), grooves (keyways, T-shaped slots, dovetail grooves, etc.), toothed parts (gears, spline shafts, sprockets), spiral surfaces (threads, spiral grooves) and various Kind of surface.
