When to Choose Micro Machining and Miniaturization
Choose micro machining when part size, feature scale or assembly density makes standard machining, molding or fabrication too coarse, risky or difficult to inspect.
- Components include micro holes, tiny slots, fine pins, miniature shafts or compact sensor interfaces.
- Medical, electronics, optics or aerospace assemblies require smaller parts without losing performance.
- Thin walls, delicate features or small datums create tool access and workholding challenges.
- Burrs, surface finish, edge condition or cleanliness can affect final assembly or fluid flow.
- Inspection must verify tiny dimensions, feature position, material, finish and batch consistency.
