01CNC milling
CNC milling for housings, plates and brackets with pockets, profiles, holes and mounting faces.
CNC milling,
turning &
five-axis machining.
Machined housings, shafts and structural components, from prototypes to production orders. Send part files for a quote covering material, finishing and inspection.
CNC machining services
Parts can combine milling, turning, grinding, EDM and finishing. The quotation sets out the proposed operations and any exclusions.
01
02CNC turning
CNC turning for shafts, sleeves and housings with diameters, bores and threads. Flats and cross-holes may require additional operations.
03Five-axis machining
Five-axis machining for complex surfaces and features on several faces, with tool access and workholding planned for the geometry.

Measurement probe and component fixture.
Inspection and delivery documents
Inspection requirements can include dimensional checks, coordinate measurement, surface roughness and material verification. The quotation defines methods, coverage and documents.
- 01
Drawing requirements
Critical dimensions, datums, fits and surface conditions form the acceptance criteria.
- 02
Inspection reports
Measurement methods, report contents and sample coverage are agreed for the order, with reporting costs identified in the quotation.
- 03
Drawing revision
Matching model and drawing revisions keep the inspection scope tied to the part being ordered.
Design review examples
Three illustrative design exercises: an airflow prototype, a transmission component and an aluminum structure.
Engineering example / PrototypeAluminum airflow

Turning, gear features
and mating fits.
A transmission component can combine turning, gear features and secondary operations, with fits, burrs and critical dimensions in one finished-part definition.
