CNC machining can be defined as automatically and digitally controlled machining processes. Main machining processes include:
· Milling, where the spindle rotates removing material.
· Turning, where the cylindrical workpiece rotates while spindle is fixed removing the material
· Drilling, where a hole is cut into the workpiece
· Grinding, where a rolling, abrasive wheel removes light amounts of material
· Sawing where material is cut (into parts) with a blade.
· Finishing operations （1-Filing that is about light amounts of material removing, combining grinding and sawing and is used mostly in deburring. 2-Polishing and brushing, where a smooth or shiny surface is created with abrasive process.)

Available CNC machining services
| Name | Description |
|---|---|
| CNC Milling service | CNC milling is a subtractive manufacturing process that rapidly removes material from metal or plastic blocks to produce precision parts with tight tolerances. |
| CNC Turning service | CNC turning produces parts with cylindrical features by removing material from metal or plastic rods using cutters, center drills or live tooling. |
| 5-axis CNC machining | 5-axis CNC machines can produce parts with complex geometries and increase productivity by minimizing the number of machine setups. |
