CNC Milling Services
We machine CNC-milled prototypes and production parts in metals and engineering plastics, with inspection documentation available on request.
3/4/5-axis CNC milling, typical tolerances ±0.05–0.10 mm; tighter tolerances on CTQ features with GD&T and CMM-based inspection (part-dependent).
AS9100D | ISO 9001:2015 | ITAR Registered
Custom CNC Milling
We machine custom CNC milled parts from prototypes to production runs. Our work supports multi-face datums, deep pockets, thin features, and complex geometry for accurate fit and reliable assembly.
- Multi-face datums for complex parts
- CTQ features with GD&T-defined inspection
- CMM report / Dimensional report / FAI

Precision manifolds & flow blocks
Internal pockets/ports with positional control for sealing and flow alignment
Covers, baseplates & fixtures
Planar surfaces, parallelism, and multi-face datum relationships
Heat sinks & thermal plates
Fin features, surface contact area, and consistent thickness control
5-axis complex geometry components
Multi-side machining to reduce re-setups and improve datum consistency
Why Choose Kemal for CNC Milling Services
DFM Before Machining
DFM feedback is provided during quoting, covering tolerances, datum strategy, and high-risk features, so potential issues are resolved before machining begins.
5-Axis Capability for Complex Parts
5-axis CNC milling enables multi-side machining in a single setup, reducing re-positioning error and improving datum consistency on complex parts.
CTQ-Driven Quality Control
CTQ features are identified upfront and verified through defined inspection requirements, including CMM reports or FAI when specified on the drawing.
Predictable Lead Times
All CNC milling is performed in-house on our own machines, allowing tighter schedule control and more predictable delivery timelines.
Revision & Rebuild Support
Design revisions are managed through controlled change tracking, ensuring consistency across re-builds from prototype iterations to production parts.
No MOQ
No minimum order quantity (MOQ) allows flexible ordering for prototypes, re-builds, and low- to mid-volume production.
FAQs
Lead time depends on part complexity, material, and axis selection. Simple 3-axis CNC milled parts can be completed in as fast as 1 day, while most 4- and 5-axis projects are delivered in about 5 business days. Expedited options are available for urgent requirements.
Typical CNC milling tolerances are ±0.1 mm for most parts. Tighter tolerances down to ±0.05 mm are available for 5-axis parts, depending on geometry, material, and inspection requirements.
We machine a wide range of metals and engineering plastics for CNC milling, including aluminum, stainless steel, carbon steel, titanium, and brass, as well as ABS, polycarbonate (PC), nylon, polypropylene (PP), and acetal (POM).
Yes. We support CNC milling for prototypes, design iterations, and low-volume production runs, with in-house machining to maintain consistent quality and predictable lead times from first parts through repeat builds.
Yes. Inspection reports and first article inspection (FAI) are available upon request. Options include CMM and dimensional reports aligned with your drawing and validation requirements.
Yes. Post-machining finishing options are available, including anodizing, bead blasting, polishing, electropolishing, tumbling, and heat treatment, based on your part specifications.
Send your CAD file and drawing (tolerances, material, finish, and quantity). We’ll return a quote with lead time, key manufacturability notes, and optional inspection/documentation items if required.
