Final capability depends on part geometry, material, process and the agreed inspection method.Your manufacturing partner
One contact. Project-matched manufacturing.
One point of contact
CathayPort coordinates drawing revisions, supplier questions and production updates.
Machining + finishing
Coordinate machining and surface treatment in one RFQ, including masking and finished-part dimensions.
Prototype to repeat orders
Plan samples, initial batches and repeat production around your purchasing schedule.
Machining processes
Milling, turning & specialist operations.
CNC milling
Plates, brackets, housings and pockets. Three-, four- or five-axis routes are selected after geometry review.
CNC turning
Shafts, bushings, spacers and rotational parts with bores, grooves and threaded features.
Multi-axis machining
Multi-sided features and complex surfaces, with setup and tool access reviewed before quotation.
Additional operations
Ask about grinding, wire EDM, EDM and turn-mill work when your drawing requires a specialist process.

Technical buying guide
Tolerances, sizes & delivery.
| Parameter | Requirements & confirmation |
|---|---|
| Milling part size | Reviewed from your 3D model and overall dimensions.Include the full envelope, workholding surfaces and any heavy or thin-wall features. |
| Turning part size | Diameter and length confirmed with the selected partner.Include stock diameter, finished length, bore depth and concentricity requirements. |
| General tolerances | The applicable standard and grade are agreed in the quotation.If required, specify ISO 2768-1 and its tolerance class. Otherwise, we clarify unspecified dimensions before production. |
| Critical dimensions & GD&T | Confirmed feature by feature after drawing review.Mark fits, datum references, position, flatness, runout and other functional requirements on the 2D drawing. |
| Surface roughness | Agreed for the specified surfaces and manufacturing route.State Ra values in μm and identify sealing, sliding and cosmetic surfaces. |
| Threads, holes & thin walls | Reviewed for tooling access, stability and inspection.Specify thread standard and fit, blind-hole depth, inserts and any distortion-sensitive areas. |
| Quantity & repeat orders | Prototype, initial batch and repeat-production enquiries.Share the order quantity, expected annual volume and planned releases. |
| Lead time | Confirmed with material availability, capacity and finishing steps.Tell us your required delivery date and destination so the quotation can include a realistic schedule. |
Surface finishing processes
Machining + finishing, or finishing only.
Enquire about these processes for new CNC parts or customer-supplied products. Compatibility, partner availability and acceptance criteria are reviewed before quotation.
Anodizing
Clear, black, colour and hard anodizing requests.
Electroplating
Nickel, chrome, zinc and tin plating requests.
Electroless nickel
Specify coating thickness and required properties.
Passivation & conversion
Stainless passivation, chemical conversion and black oxide requests.
Blasting & brushing
Bead blasting, sandblasting and directional brushed finishes.
Polishing
Mechanical polishing and electropolishing requests.
Painting & powder coating
Specify colour reference, texture, gloss and masking.
Marking & printing
Laser marking, engraving and silk-screen printing requests.
Quality & documentation
Inspection planned with your order.
First-article review
Agree sample approval and critical-feature checks before releasing the production batch.
Dimensional reports
Define the measurement scope, sampling plan and reporting format at quotation.
CMM inspection
Request CMM measurement for suitable features; availability and cost are confirmed with the inspection plan.
Material & finish records
Request material certificates, coating checks or test reports before ordering so the required records can be arranged.
