Custom OEM CNC Machining Parts - Precision CNC Parts, Built Like They Should Be
When buyers in the USA, UK, and Europe need CNC parts, they do not ask for buzzwords. They ask for clean tap holes, consistent threads, no finish marks, and tolerances that hold in real world conditions. That is what our CNC machining services are built to deliver.
We machine custom metal alloy like aluminum, brass, and stainless steel parts with ±0.10 mm precision. From 5-axis prototypes to mass production, each CNC component leaves our floor fully inspected, burr-free, and dimensionally exact.

We make parts Aluminum CNC Parts for USA automation systems, for UK drone prototypes, and medical parts for Germany. Our one job last quarter needed ±0.05 mm across bores. First tool ran hot, slight taper showed on bore two. We caught it early, swapped to a coated cutter, and dialed in coolant feed. That batch ran clean after that.
Materials We Know Inside Out
We do not try to be everything to everyone. Instead, we specialize in the materials our machines and machinists that know inside out.
- Aluminum - 6061, 6063, 6082, 7075
Quick to cut. 6061, we slow the finish pass. Threads need sharp taps and they shred. - Brass - C360, CZ121, C385
No coolant, full RPM. Chip clears easy. Tight finish in one pass. - Stainless - 304, 316, 303
Gummy. We use high feed mills and sharp inserts. Slow the last 0.5 mm. - Mild Steel & Carbon Alloys
Standard runs for brackets, fixtures, and tooling. - Copper & Bronze
Soft and grabby. We reduce depth per cut, keep tools razor sharp. - Engineering Plastics - Delrin, Nylon, PTFE, PEEK
PEEK needs high-end fixturing. Nylon melts easy. Delrin cuts clean if dry.
Every material needs a different strategy and we do not just use the same feed rate and hope it works. Whether it is dry-cutting brass or slow-feed finish passes on stainless, we match the approach to the material every time
Complete CNC Machining Parts Capabilities
Turning (Ø150 mm Max)
- Stepped shafts
- Thread cutting – metric, UNC, BSP, UNF, BSPT
- Terminal ends, pins, spacers, threaded inserts
- Grooved features, O-ring seats
- Live checks every 10 parts
We regularly deliver USA and Europe cnc turning parts for electrical connectors, sensor housings, spacers, bushing, fittings and mounting studs. Each part is run with real time checks and in-process inspection, not just batch checked at the end.
One batch of brass studs ran with a chip weld on the insert we scrapped 3, cleaned the insert pocket, and ran the rest smooth.
Milling (3-axis, 4-axis, 5-axis)
- Flats, keyways, slotted blocks
- Frames, plates, clamps
- Engraving, chamfering, counterboring
- Block size up to 400 x 300 mm
- Nested setups for mid-volume production
Complex cnc milling parts often involve both drilling and profile cuts, and we understand how to fixture and tool these for speed and accuracy. We also run nested part setups when production volume calls for it.
We fixture in steel jigs, run dry on aluminum, and debounce every corner before pack out.
5-Axis Machining - For Complex Parts
When jobs call for tight tolerances on multiple faces and unusual part geometries, we turn to 5-axis capability. It is not just about doing fancy cuts, it is about reducing setups, improving precision, and keeping everything in one zero-point reference.
- Angled holes
- Compound faces
- Multi op reduction
- Tight datums held from single zero point
Tolerances & Threads - Where It Matter
- Threads: UNC, UNF, Metric, BSP, NPT
- Tapping: Blind, through, vertical, side
- Bores: Reamed to ±0.05 mm
- Tolerances: ±0.05–0.10 mm production, tighter on prototype.
We check parts on mid-run. Not just at final check dispatch time. Micrometers, bore gauges, plug pins and no overreliance, on calipers.
Finishing & Post-Processing
- Vibratory deburr, manual polish
- Chamfers on all thread exit
- Surface: nitric, brushed, matte, buff
- Plating: nickel, gold, tin, silver, as per requirements
- Press-fit inserts, heat-set threads
- QR code labels, every part batch tagging
One medical client in Texas needed matte-black anodized bracket. We did full pilot run and verified finish on 3 lots then scaled.
Common CNC Part
- 6061 Aluminum Bracket - Used in UK drone prototypes, bead-blasted, ±0.10 mm
- C360 Brass Threaded Insert - Molding press fit, nitric finish, shipped to USA
- Stainless Valve Housing - 316SS, side tapped, polished ports for German pharma
- Mild Steel Spacer Ring - Chamfered ID/OD and black oxide finish
- Sensor Mounting Plate - 6082 aluminum, engraved with milled standoff
- Copper Neutral Bar – Flat milled, deburred edges
Each part run differently, every part we have to fix setup differently, but goal is same quality parts for customers

How We Maintain CNC Quality Standards
- First Article Checks: Before full run
- In-Process Inspection: Every 5–10 pcs, adjusted on the fly
- Final QA: Batches tagged, verified, and signed
- Tooling Maintenance: Cutter wear logs, tool presetting
- Machine Calibration: Verified monthly with gauge block
- Operator Skill: Jobs stay with same machinist when possible
We do not just inspect parts, we inspect the setup. That is how we avoid batch drift.
CNC Machining FAQ
Q1: What tolerances can you hold for CNC parts?
We regularly hold ±0.10 mm. For reamed holes and tight features, ±0.05 mm is possible. Depends on geometry, material and customer requirements.
Q2. Can you handle both low volume prototypes and high volume mass production runs?
Yes. We run small batches for prototyping, pre-series testing. On the other end, we also handle monthly schedules of 10,000+ mass production parts with tool life monitoring and batch traceability. You will get the same dimensional quality across both.
Q3: Do you offer machining for OEM custom parts?
Yes. We accept custom part as per requirements and product drawing or samples.
Q4: What finishes can you provide?
Brushed, matte, bead-blasted, tumbled. Plating available via partners , nickel, tin, gold, silver.
Q5: Can you ship CNC parts to the USA and Europe?
We already do. Regular shipments to USA, UK, Germany, Italy, and more with tracked delivery and lot ID tagging if needed.
Q6: Can you provide surface finishing like anodizing and powder coating?
We can deliver CNC parts with clear or black anodizing, chemical film, bead blasting, and powder coating. Let us know which finish type you need, coating thickness, and color (if applicable). Finishing adds 2 to 3 working days depending on the volume.
Q7: What is your standard lead time for CNC orders?
Standard lead time is 7 to 10 working days for most aluminum and brass CNC job. For complex 5-axis and large-volume batches, it can be 15 to 20 days. If you have a hard deadline, tell us upfront. We do not promise what we cannot ship.
Q8: Do you ship CNC machined parts internationally, including the USA and Europe?
Yes. We regularly ship CNC parts to the USA, UK, Germany, Italy, Netherlands, and Singapore. Shipments are packed with protection, corner guard, and dimension checks. DHL, FedEx, UPS, and sea freight options available based on customer part volume and urgency.
Q9: Can you machine parts directly from 3D files or do you need 2D drawings?
We accept both. STEP file is best for CAM programming. But if your part has GD&T tolerances, thread specs, and special notes, send a PDF drawing too. That saves guessing and avoids revision delays.
Q10: Can I get a prototype first before placing full batch order?
Yes, and we recommend it. One prototype tells you everything fitting, finish, tolerance issues. Once the prototype is confirmed, we use the same setup sheet for the full batch. No surprises during scaling.
Why CNC Buyers Choose Us
- Ask questions - if your drawing has issues, we do not ignore it
- Run test pieces - before blowing through 500 pcs
- Fix issues mid-run - tool broke? We stop and fix, not fudge the result
- Think like builder - if there is a better setup, we tell you
- Quote real timeline - no fake 2-day promise unless we mean it
