Machined components can range from simple shafts and bushings to highly complex aerospace connectors and medical instrument parts. Depending on the application requirements, manufacturers can produce parts with different tolerance levels, surface finishes, hardness values, and coating treatments.
Common machining processes include:
- CNC turning
- CNC milling
- Surface grinding
- Drilling and tapping
- EDM machining
- Laser cutting
- Wire cutting
- Precision grinding
- Polishing and deburring
These processes help ensure that each component meets engineering standards and industrial specifications.
