Product Overview
GPT Precision manufactures custom CNC-turned components according to customer drawings, including stepped shafts, mangas, bushings, threaded parts and components with internal or external rotational features.
Our manufacturing review considers material grade, geometry, stock form, sujeción, secondary operations and inspection requirements.
For components with critical fits, the relationship between the locating diameter, datum axis and adjacent shoulders is often as important as the dimensions of the individual features.
Key Features
- Consider a shaft containing a bearing seat and a locating shoulder.
- The bearing seat controls radial fit, while the shoulder establishes the bearing's axial position.
Manufacturing Considerations
- If a second setup is necessary, the part must be located from suitable features consistent with the specified datum system.
- Finished functional surfaces should also be protected from gripping damage. Soft jaws, suitable sleeves or other workholding arrangements may be considered according to the component geometry.
Control de calidad & Inspección
- After operations affecting the fit are complete, the released shaft is inspected according to the drawing requirements.
- Checks may include diameter at specified axial positions, shoulder location, and face runout relative to the required datum axis.
- The inspection approach is confirmed according to the part and its acceptance requirements.
Specifications to Confirm
| Bearing seat | Confirm the fit diameter and axial measurement positions. |
|---|---|
| Shoulder face | Specify axial location and face runout where required. |
Assembly Considerations
Bearing fit and location
Check that the mating bearing can seat against the shoulder with clearance at the transition radius.
