Machining Services
CNC Machining.
Tight tolerances. Repeatable runs. Real materials.
3-, 4- and 5-axis CNC milling and turning across stainless, carbon steel, aluminum, brass, copper and engineering plastics. Mastercam-driven CAM, 10,000+ CAD drawings already vetted, and an in-house QC program with documented inspection reports on every shipment.
Capabilities
One supplier across the full CNC machining stack - milling, turning, hobbing, and the supporting processes that turn raw stock into a packaged, inspected, ready-to-install part.
CNC Milling
3-, 4- and 5-axis vertical machining centers from Okuma, Takisawa Sunmill, Ares-seki, Takumi and Dahlih. Prismatic parts, complex geometries, prototype to series production.
CNC Turning
Fixed-head and Swiss-style sliding-head lathes from Nomura, Star, Moriseiki, Miyano and Takisawa. Live tooling for cross-drilling and milling features in one setup.
4- and 5-Axis Machining
True simultaneous 5-axis for impellers, manifolds, surgical instruments and complex aerospace geometries. Single-setup machining keeps tolerances stacked tight.
CNC Hobbing
Dedicated hobbing for gears, splines and key slots. Module ranges and tooth counts to your spec.
Water Jet and Plasma
CNC water jet for sheet-stock profiles in heat-sensitive materials. CNC plasma for thicker plate. Both feed directly into downstream finishing operations.
Finishing and Post-Processing
Anodizing (clear and colored), heat treatment and case hardening, plating, painting, polishing, friction welding and standard welding - all under the same roof.
Built on industry-standard equipment
High-precision machining centers from the brands you already trust.
Programming and CAM in Mastercam. Additional brands include Ares-seki, Takumi, and Dahlih.
From your CAD to a finished part
A predictable, four-stage workflow that has moved 10,000+ drawings through our shop. You get a quote, a lead time, and a finished part with a documented QC record.
CAD validation
Submit a 2D or 3D CAD plus material, surface finish and quantity. Our DFM engineers vet the drawing, flag features outside our envelope, and propose cost-down options before a quote is issued.
Programming
Skilled CNC programmers convert your CAD into Mastercam toolpaths for the machine that fits the part - mill, fixed-head lathe, or Swiss-type sliding-head.
Production
Manufactured on the right machine for the job, with first article inspection and in-process checks. Post-processing (anodize, plate, heat-treat, polish) runs in the same facility.
QC and shipment
Documented QC inspection report ships with every order. Choose from Ex Works, FCA, FOB, CIF, DDP or DDU - sea or air freight via FedEx, DHL, UPS, TNT or EMS.
Materials we machine
Almost any commercially available metal or engineering plastic. Common grades below; submit anything else and we will quote it. Sheet-metal stock approaches typically cost less than rod or plate machining where geometry allows.

Tolerances and finishes
Standard tolerances
- ISO 2768 medium for general features
- ISO 2768 fine on parts that call for it
- Tight features held to plus or minus 0.005 mm on request
- True position to 0.02 mm achievable on machined faces
Surface finishes
- As-machined: Ra 1.6 to 3.2 micrometer typical
- Fine machining: Ra 0.4 to 0.8 micrometer
- Polishing, lapping, vibratory deburring on request
Coatings and post-processing
- Anodize (Type II clear, Type II dyed, Type III hard)
- Zinc, nickel and chrome plating
- Powder coat and wet paint
- Heat treat (annealing, quench and temper, case hardening)
- Friction welding and standard welding
Standard machining operations
CNC machining vs 3D printing
3D printing wins for design freedom, rapid concept iteration and short-run prototypes in light geometries. CNC machining wins when the part has to perform - tighter tolerances, superior strength, real material properties, refined surface finish.
The honest answer is that the two are complementary. We routinely see customers prototype with 3D prints, then move to CNC machining the moment the part is ready for sample testing or production.
Choose CNC machining when:
- Tight tolerances are non-negotiable
- You need real material properties (heat-treated steel, certified aluminum, food-grade stainless)
- Surface finish, fits and threads matter
- The part will see load, fatigue or fluid pressure
- You're moving from prototype to production volume
