Drawing-based components
PTFE components with pockets, bores, threads and stepped surfaces machined from a dimensioned model. Define functional datums and feature-specific tolerances.
Procurement specification
These components are made to the required geometry. The drawing defines the finished dimensions and interfaces.
| Geometry | Pockets, bores, shoulders, threads and profiles |
|---|---|
| Design inputs | Dimensioned drawing plus CAD model where available |
| Tolerance approach | Feature-specific fit and datum requirements |
| Material input | Identified virgin or filled PTFE stock |
| Inspection focus | Functional dimensions and drawing revision |
A model defines shape, while the drawing identifies the dimensions that control function. Set datums for locating bores, mounting faces and hole patterns so inspection follows the assembly intent.
Do not apply the tightest tolerance to every feature by default. Thin walls and flexible sections need tolerances that account for support, temperature and measurement conditions.
The starting stock and the order of operations affect how a soft polymer part is supported. A turned bore, milled pocket and final face may need different holding arrangements.
Threads and slender features require their engagement and loading duty to be defined. For prototype approval, record the measured critical features and the drawing revision used.
Specific answers
This page specifies the purchased component. The capability page explains the machining process and when it fits a geometry.
A model alone usually does not define tolerances, datums, finish or inspection criteria. Supply a drawing for those requirements.
