What is CNC Machining?
CNC machining is a precision manufacturing method where cutting tools are guided by computer-controlled programs to remove material from a solid workpiece.
Because material is removed rather than added, CNC machining is well suited to metals, engineering plastics, and composites.
Modern CNC machines operate across multiple axes simultaneously.
The Machines We Use
CNC Milling
Rotating cutters work across a fixed workpiece.
What Tolerances Can We Hold?
Standard CNC machining at Oyster-CNC works to general tolerances of ±0.1mm as a baseline.
What Tolerances Can We Hold?
| Process | General | Precision | Notes |
|---|---|---|---|
| CNC Milling (3-axis) | ±0.1 mm | ±0.02 mm | Positional accuracy depends on fixturing |
