What is CNC Machining?
Computer-controlled machines are able to cut and shape metal blocks for prototyping and manufacturing.
How It Works
CNC Machining starts with a raw block of metal that gets cut away and shaped
down to the final shape by computer-controlled machines, such as mills and lathes. This process is typically
used for manufacturing, fixtures, and even art, but it can also be used to create product prototypes.
Typical Uses
- Production Parts
- Special-purpose Parts or Fixtures
- Rapid Prototypes
Costs

So, you can see how volume discounts can be a big factor, especially for processes that are slow in the vertical direction.
