This guide helps screen geometry before an RFQ. It does not approve a process. A verified machine, manufacturing source, material route and inspection plan are still required.
Often a Good Starting Point
- Predominantly round geometry beginning from bar-shaped stock
- Several coaxial diameters, shoulders, grooves or end features
- Features on both ends
- Small threads, flats, slots or cross-holes
- A repeat requirement where process consistency matters
Needs Additional Review
- Heat-treated bearing or press-fit surfaces
- Very slender shafts with strict final straightness
- Thin walls or dimensions that change after installation
- Gear teeth, splines, worms or critical internal bores
- Coating or secondary processing that changes final dimensions
- Assembly, balancing or functional-test requirements
Usually Not a Swiss-Type Starting Point
- Large plate, housing, flange or structural components
- Extensive off-center or multi-face milling
- Parts dominated by precision gear finishing
- Dedicated composite, wrapped or sintered bearing products
- Standard catalog hardware with no clear custom requirement
