# CNC Machined Enclosures & Housings

> CNC milling is a strong route for custom enclosures when the part needs precise connector locations, bearing or seal interfaces, threaded inserts, and better stiffness than a formed enclosure. FabVector machines one-off prototypes and repeat batches, with inspection tied to the drawing rather than a blanket tolerance claim.

## Typical applications

- Electronics and sensor enclosures
- Robot joint and gearbox housings
- Optical instrument bodies
- Pump, valve and actuator housings

## Recommended manufacturing route

1. Machine primary mounting datums and rough the cavity before thin walls are released.
2. Finish bearing bores, seal grooves and connector faces from controlled setups.
3. Deburr internal intersections and protect critical faces before finishing.
4. Inspect interface dimensions, then install inserts or seals only when specified.

## Drawing and RFQ controls

| Control | Guidance |
|---|---|
| Wall thickness | Keep walls uniform where possible; identify flexible walls that need a free-state inspection method. |
| Internal corners | Use realistic tool radii; deep square corners require EDM or a design change. |
| Sealing faces | State flatness, surface finish and gasket or O-ring requirements together. |
| Cosmetic surfaces | Mark Class-A faces and define plug or masking zones before anodizing or coating. |

## Inspection scope to define before production

- CMM report for mounting datums, bores and connector locations
- Flatness and surface-finish verification on sealing faces
- Thread gauges and fit checks for inserts and mating hardware

## Buyer questions, answered

### What files are needed to quote a machined enclosure?

Send a STEP model plus a PDF drawing that identifies datums, toleranced interfaces, threads, finish, quantity and inspection requirements. The drawing controls where the model is nominal only.

### Can deep enclosure cavities be machined without distortion?

Usually, but the route may need staged roughing, stress relief, soft jaws and a final free-state inspection. Wall thickness, depth and material condition determine the risk.

### Can anodizing be included with the machining quote?

Yes. Specify anodize type, color, cosmetic faces, masked threads and any dimensions that apply after coating so machining allowance and inspection are planned together.

### What enclosure quantity can FabVector quote?

The published minimum is one piece. Prototype and repeat-production quantities can use the same RFQ, but final lead time and price depend on geometry, finish and documentation scope.
