What Are CNC Turning and Milling?
CNC Turning Process
CNC turning is a machining process that involves rotating a workpiece while a cutting tool removes material to create cylindrical parts. This process is ideal for producing components such as shafts, pins, bushings, and other rotational symmetric parts. The workpiece is mounted on a spindle and rotated at high speeds, while the cutting tool moves linearly to create the desired shape and dimensions.
Key characteristics of CNC turning include:
- Excellent surface finishes (Ra 0.8-3.2 μm)
- Tight tolerances (±0.005-0.02 mm)
- High production efficiency for cylindrical parts
- Ability to create complex features like threads, tapers, and grooves
CNC Milling Process
CNC milling is a versatile machining process that uses rotating cutting tools to remove material from a workpiece. Unlike turning, where the workpiece rotates, milling machines move the workpiece along multiple axes (X, Y, Z) while the cutting tool spins. This allows for the creation of complex shapes, slots, holes, and three-dimensional features.
Advantages of CNC milling include:
- Versatility in producing complex geometries
- High precision for both simple and intricate parts
- Ability to machine multiple surfaces in a single setup
- Compatibility with a wide range of materials
