Precision CNC Machining Services
Your designs demand more than just a shop that can run a CNC machine. They require a manufacturing partner who understands tight tolerances, material properties, and design for manufacturability (DFM).
We provide full OEM machining support and specialize in 3-, 4-, and 5-axis CNC milling and turning. Delivering the same precision and consistency whether it’s a single prototype or a 10,000-part production run. Contact our engineers today for a free expert quote.

CNC Milling
We have 3, 4 and 5 axis machining capablities for simple and complex geometries, holding dimensions to tolerances as tight as 0.002”.
CNC Turning
We have CNC turing capablites for custom precision threads, deep holes, and all types of intricate cylinder and round shapes.
EDM
Electrical discharge machining (EDM) capabilities for deep pockets, complex features, and precision cutting of hard metals.
CNC Machining
CNC, or computer numerical control machining, is a widely used manufacturing process that uses automated, high-speed cutting tools to form designs from metal or plastic stock. Standard CNC machines include 3-axis, 4-axis, and 5-axis milling machines, lathes, and routers. Machines may vary in how CNC parts are cut—the workpiece may remain in place while the tool moves, the tool may remain in place while the workpiece is rotated and moved, or both the cutting tool and workpiece may move together.
Advantages and drawbacks of CNC machining
ADVANTAGES
CNC milling and turning are highly accurate and repeatable processes.
Using standard tooling, a CNC machining service is particularly valuable for creating one-off parts, custom CNC parts.
Achievable mechanical properties.
DRAWBACKS
One trade-off when taking advantage of the high performance of CNC machining processes is that geometric complexity comes at a cost.
Start-up CNC machining costs can be expensive.

Post Processing For CNC Machining
Surface finishes can serve either a functional or aesthetic purpose. Surface finishes that serve both purposes are deemed cosmetic finishes, and are used for cosmetic parts. Producing cosmetic parts requires additional measures to minimize defects such as hang marks and scratches from tools.

High quality parts every time
Precision products machining
From factory audits to part inspections, we follow strict processes to ensure your parts always meet the highest quality standards.
IP protection
We take every measure to ensure the protection of your IP, which is why 27% of Fortune 500 companies trust us with their projects.
Certifications
Our manufacturing partners have all the necessary certifications for your project's needs (ISO 9001, ISO 14001, IATF 16949, ISO 27001).
TESTIMONIALS
Amazing experience. All the expectations fulfilled. Exceptional quality and surface finish. Lead time faster than initially stated.
During the process, we used HLHs capabilities to 3D print many prototypes. That meant we had the option to iterate very quickly, print objects, and test them to see if they were working correctly in terms of complexity, or too much complexity.
HLH has always given us exactly what we needed. We’ve received parts with holes in the right places, with the right finish, and on time. Their user-friendly website means faster turnaround.
