Capability / CNC Machining

CNC machining for critical features after die casting

Secondary machining turns a cast shape into an assembly-ready part by controlling bores, faces, threads, seals and reference features.

CNC Machining in project context

Die casting creates the part geometry. CNC machining controls the features that cannot be achieved reliably by casting alone, including bearing bores, sealing faces, threaded holes and tight interfaces.

The machining plan should be defined with the casting drawing. Datum strategy, stock allowance, workholding, tool access and inspection method need to agree with the casting process.

Technical profile

CNC Machining planning data

Use this table for project planning, then confirm every critical value against the approved drawing and process plan.

Operations	Milling, drilling, tapping, reaming, boring and turning
Machining equipment	30+ CNC units: 20 machining centers and 10 CNC lathes
Machine types	3-axis and 4-axis machining centers; CNC turning by project
Tolerance	±0.05 mm as cast; ±0.01 mm on machined features
Workholding	Fixture concept defined with casting datums and stock allowance
Inspection	Dimensional report and functional checks defined before production

Figures reflect current factory equipment and capacity. Final tolerances, cycle time and lead times are confirmed against the drawing in the quotation.

Project flow

How a cnc machining project moves forward

Each stage produces a decision or document that the next stage depends on. This keeps engineering, purchasing and production aligned.

Datum review

Define casting datums, machining datums and inspection datums.

Stock planning

Confirm casting allowance, fixture access and first-operation stability.

Process design

Select machines, tools, fixtures and inspection frequency.

Release

Approve first article and control the approved process through production.

Buyer questions

Questions to resolve before production.

These answers define the normal project path and the information needed for a useful quotation.

What information is needed for a cnc machining review?

Provide the controlled 2D/3D drawing, material requirement, annual quantity, finishing requirement, critical dimensions, target market and delivery date.

Can the project start from a sample or concept?

An initial feasibility discussion is possible, but the quotation and tooling scope should be based on a controlled drawing revision.

How are tolerances set?

Tolerance and inspection requirements are defined from the drawing, critical features, process capability and agreed datum strategy.

How is tooling ownership handled?

Ownership, storage, maintenance and transfer terms are defined in the quotation or supply agreement before the tooling project starts.

Continue through the project path.

Use the internal links to connect the material, process, industry, product and RFQ pages around one project decision.

Send the drawing. Get the engineering questions first.

Include the material, annual quantity, finishing requirement, target market and delivery date. The review can start from STEP, IGS, DWG, DXF, PDF or ZIP files.
