Near-net-shape castings can still need machining where assembly fits, sealing faces or other critical dimensions demand a defined final condition. Treat the casting blank and the machined part as a connected manufacturing plan.
Why Combine Investment Casting with In-House CNC Machining
Drawing-defined dimensional tolerances
Machine critical features to the agreed drawing while distinguishing them from general as-cast geometry. Confirm tolerance feasibility feature by feature.
One coordinated technical scope
Discuss casting stock, fixturing, machining access and inspection together, reducing the handovers involved in separately specifying a blank and finished part.
Consistent quality-control requirements
Use the same drawing revision, material condition and acceptance plan across the route. Agree how changes are reviewed before production.
Parts prepared for final assembly
Define finished interfaces, cleaning, protection and documentation so the supplied condition matches what the next assembly step requires.
Our In-House CNC Machining Capabilities
Tolerance capabilities
No fixed numerical tolerance is applied to every material or feature. Send critical dimensions, datums and inspection requirements for a component-specific capability review.
Machining operations to specify
| Review area | What to define in the enquiry |
|---|---|
| Milling | Faces, slots and profiles shown on the drawing. |
| Turning | Rotational features and finished diameters. |
| Boring | Final bore requirements and their reference features. |
| Drilling | Hole patterns, depth and access. |
| Tapping | Thread specification, depth and acceptance. |
The exact operation mix, equipment and size limits are confirmed during drawing review.
Materials Suitable for Post-Casting CNC Finishing
Review stainless steels, carbon steels and specified alloy requirements. The material condition and manufacturing sequence affect the machining proposal.
Complete Project Workflow: Casting to CNC-Finished Parts
Drawing & DFM → Casting plan → Casting blank → CNC machining → Specified secondary processing → Final inspection
Additional Value-Added Secondary Services
In-house heat treatment and surface processing can be discussed with machining. Plating, painting, blasting, polishing and assembly are RFQ options to verify, not automatically included services.
