2. How Does CNC Milling Work?
CNC milling follows these essential steps:
- Designing the Part – A CAD (Computer-Aided Design) model is created.
- Programming the CNC Machine – The design is converted into a G-code that guides the machine.
- Material Selection and Setup – The raw material is placed onto the milling bed.
- Milling Operation – A cutting tool removes excess material to achieve the final shape.
- Finishing and Quality Control – The product is polished, tested, and inspected.
3. Types of CNC Milling Machines
There are different types of CNC milling machines, each designed for specific applications:
- Vertical Milling Machines – The spindle is vertically oriented, ideal for detailed cutting.
- Horizontal Milling Machines – The spindle is horizontal, used for heavy-duty cutting.
- 3-Axis CNC Mills – Moves in X, Y, and Z axes, perfect for basic milling.
- 5-Axis CNC Mills – Allows movement in five directions for complex geometries.
