Types of CNC Machining

CNC machining refers to a broad range of machining equipment types that use computer numerical control to guide and automate complex cutting and forming processes. Some of the most common types of CNC machining include:

Drilling

Drilling relies on multi-point drill bits to form cylindrical holes in a workpiece. Using CNC machining equipment provides precision computer-guided control over the drill bit, allowing the formation of highly precise vertical holes. CNC drilling allows the incorporation of more complex drilling processes such as countersinking, counterboring, reaming, and tapping using specialized tooling and workholding solutions, also facilitating the creation of angular holes.

Milling

A reductive machining process, milling uses rotating multi-point cutting tools to remove material from the workpiece in accordance with design specifications. In manual milling operations, operators traditionally feed the workpiece into the machine in a direction counter to the rotation of the cutting tools. With CNC equipment, however, the cutting tools can perform precision cuts even while the workpiece rotates in the same direction. The versatility of CNC milling allows capabilities such as:

  • Face milling. Face milling is used to make cuts on flat surfaces or to create flat-bottomed cavities within a workpiece.
  • Peripheral milling. This milling process cuts deep slots or threads into the workpiece.

Turning

Turning is another reductive machining method that uses a single-point cutting tool (or multiple single-point cutting tools) to cut material away from the workpiece. Turning machines rotate the workpiece rapidly while the cutting tool presses against the surface to remove the material. CNC turning machines, also sometimes referred to as CNC lathes, are most commonly used to create cylindrical parts. CNC turning machines can handle a variety of tasks, such as:

  • Boring
  • Facing
  • Grooving
  • Threading

Other CNC Machining Operations

Numerous other machining processes are compatible with CNC technology, such as:

  • Broaching
  • Sawing
  • Grinding
  • Honing
  • Lapping

Materials

CNC machining is compatible with an expansive range of materials, including:

  • Aluminum
  • Brass & copper
  • Composites
  • Exotic metals/alloys
  • Precious metals
  • Plastics/polymers
  • Stainless steel
  • Steel
  • Super hard specialty alloys
