Product Overview
GPT Precision manufactures custom CNC-machined POM components according to customer drawings.
Applications may include guides, bagues, spacers, locating elements and sliding mechanical parts.
POM grade, operating temperature, load, environmental conditions and functional fit should be considered when defining requirements.
Key Features
- Thin guide walls, a sliding slot and a controlled entrance edge.
- Consider a POM guide with a narrow sliding slot.
- A local constriction along the guide may restrict movement even when the mating slider enters the opening.
Manufacturing Considerations
- During machining, clamping pressure may deflect the slot walls and temporarily change the opening width.
- When the component is released, the walls can return toward their unloaded shape.
- The component should be supported during machining without unnecessarily compressing its functional guide walls.
- Entrance edges may require controlled deburring or edge breaks.
- Removing too much material can shorten the intended guide contact region or affect alignment.
- The allowable edge condition should be established from the design requirements.
Contrôle de qualité & Inspection
- After machining and required finishing, the slot can be checked at specified locations along its length.
- Where free-state dimensions govern acceptance, inspection support and measurement force should avoid introducing significant distortion.
- Functional movement checks can be agreed when appropriate for the application.
Specifications to Confirm
| POM grade | Confirm grade and operating conditions. |
|---|---|
| Free-state width | Define limits and measurement locations along the slot. |
| Edge condition | Specify the entrance edge break and required guide contact length. |
Assembly Considerations
Sliding fit
Confirm the mating slider and required clearance.
Guide travel
Identify any local constriction that could restrict movement.
