Service overview
Controlled setups for prismatic and multi-face components.
CNC milling removes material with rotating cutting tools to create faces, pockets, slots, bores, threads, and complex three-dimensional features. It is well suited to housings, plates, brackets, heat sinks, fixtures, and structural parts.
Process planning considers stock selection, setup sequence, workholding, cutter reach, deformation risk, burr control, and the relationship between machined datums and inspected dimensions.
Vertical CNC milling of pockets, bores, faces, and mounting features in a prismatic housing.
Key capabilities
Process planning connected to the drawing and end use.
The manufacturing route is reviewed around geometry, material behavior, critical features, appearance, inspection, and downstream assembly.

Industries
Applications supported across engineering teams.
Materials
Material options linked to technical guidance.
Surface Finishes
Surface Finishes reviewed for material and application fit.
Tolerances and design guidance
Define what is functionally critical.
Milled tolerances depend on feature size, depth, tool access, wall stiffness, setup relationships, material, and inspection method. Critical hole positions and mating faces should be defined from functional datums.
DG 01
Use internal radii that allow practical cutter selection.
DG 02
Keep deep narrow pockets and very thin walls limited to functional need.
DG 03
Define hole position and flatness from stable datums.
DG 04
Account for anodizing or plating buildup on close fits and threads.
Quality assurance
Inspection planning starts with the drawing.
Inspection points are selected from the controlled drawing, functional risk, process behavior, appearance criteria, and documentation requested for the project.
Datum and setup relationship review
Hole, bore, and pocket inspection
Flatness and positional checks where specified
Burr, thread, and cosmetic surface review
CMM inspection supportOptical measurement supportCalipers and micrometersThread and pin gaugesInspection documentation support
Manufacturing workflow
A controlled route from RFQ to shipment.
The exact route changes with process and project risk, but each stage keeps the approved drawings and requirements in view.

CNC Milling questions from engineering and sourcing teams.
What should I provide for a CNC milling quotation?
Send a 3D CAD file when available, a 2D drawing for critical dimensions and tolerances, material, quantity, finish, inspection, and delivery requirements. An engineer reviews the package before quotation.
When is milling preferable to turning?
Milling is generally preferred for prismatic parts with faces, pockets, slots, off-axis holes, and complex contours. Rotational parts are usually reviewed for turning, sometimes with secondary milling.
Can inserts and threads be included?
Yes. Tapped holes, threaded inserts, dowel locations, and hardware requirements can be coordinated when standards, positions, and assembly expectations are defined on the drawing.
How is lead time determined?
Lead time depends on geometry, material availability, quantity, tooling or setup requirements, surface finishing, inspection, and delivery needs. Timing is reviewed with the quotation rather than presented as a fixed promise.
