We machine custom quality aluminum, stainless steel and brass parts to your 3D CAD files. Tolerances to ±0.005 mm, 127 CNC machines, and a quote with free DFM analysis inside 12 hours.
Walls thinner than 1 mm and long unsupported sections release stress after the vise comes off. Holes drift, flatness goes, and the assembly no longer closes. Roughing, stress relief and a light finishing pass keep the geometry where the drawing says it should be.
304 and 316 work-harden the moment the tool rubs instead of cuts. Feed and speed get set too low, the edge dulls, and the surface comes back torn. On 17-4PH we set the cut for the heat-treat condition of the bar, not for generic stainless.
Free-machining C36000 cuts fast and throws fine chips. If the deburr step is loose, those chips end up in threaded holes and on sealing faces. Threads get gauged, not just checked by eye.
A callout for Ra 0.8 μm on a face that also needs anodizing is a conflict. Masking, bead blasting and hardcoat all shift the surface. Flagging that at DFM review costs nothing. Finding it after finishing costs a second run.
Aluminum, stainless and brass cut differently, so the setup, tooling and inspection plan change with the alloy.
We keep 6061, 6061-T6, 2024, 5052, 5083, 6063, 6082, 7075 and ADC12 in the material list. For thin-wall housings and heat sinks we rough, let the part rest, then take a light finishing pass so the finished walls stay parallel.
Five-axis work lets us reach the underside of a pocket in one setup. Fewer setups means fewer datum shifts, and datum shifts are where aluminum parts usually lose their tolerance.
304, 316, 316L, 303, 420, 430, 431, 440C and 17-4PH all need a cut that bites. We match carbide grade and coolant to the alloy, and we set feeds so the edge shears the material instead of rubbing it.
Brass behaves the opposite way. C36000 and C28000 want speed and clean chip evacuation, and the risk is deburring, not tool life. Every threaded hole is gauged and every sealing face is checked before the part moves to finishing.
A quick reference for the three families on this page.
| Material | Typical parts | Watch for |
|---|---|---|
| 6061-T6 aluminum | Housings, brackets, heat sinks | Thin walls releasing stress |
| 7075 aluminum | Aerospace and fixture plates | Higher cost, needs sharp tooling |
| 304 / 316 stainless | Shafts, fittings, food-contact parts | Work hardening, poor chip breaking |
| 17-4PH stainless | High-strength valves and pins | Condition affects machinability |
| C36000 brass | Connectors, bushings, fittings | Deburr of fine chips in threads |
| C28000 brass | Valve bodies, marine hardware | Long chips, slower than C36000 |
Sixteen simultaneous 5-axis centers for contoured surfaces, deep pockets and features on several faces in one setup.
27 three-axis and 12 four-axis machines handle prismatic parts, plates and simple turning work at volume.
Mill-turn centers cut round and prismatic features on the same part, so you avoid a second fixture and a second datum.
One prototype or a small batch, machined from the same alloy you plan to produce in. Useful before committing to tooling.
Brackets, chassis and covers in aluminum and stainless when the part is a formed panel rather than a machined block.
Anodizing, plating, powder coating, black oxide, bead blasting and laser marking, all arranged with inspection after finish.
Pick the machine group that matches your part envelope.

Stainless components with gauged threads and documented inspection steps.
6061-T6 is the usual answer when you need stiffness and decent corrosion resistance. It machines cleanly and anodizes well.
If weight matters more than stiffness, 5052 or 5083 bend and form better but machine slower. Send the wall thickness with the file and we will flag any feature that will move during machining.
303 contains sulfur, which breaks chips and lets the tool cut at higher feed. 304 has no such addition, so the material work-hardens under the cutting edge if the tool rubs.
We run 304 with sharper geometry, a deeper cut and a feed that keeps the tool engaged. It costs more per part than 303, and for most non-welded parts 303 is the better choice.
Yes, on features where the geometry supports it. Brass machines easily, so the limit is usually fixturing and thermal drift rather than the material.
Very thin walls or long slender features will relax after the vise opens. We will tell you at DFM review if the tolerance you asked for is not realistic on the geometry.
As-machined faces typically land between Ra 1.6 and 3.2 μm. A controlled finishing pass reaches Ra 0.8–1.6 μm.
Fine finishes down to Ra 0.2–0.8 μm are possible on selected faces. Tell us which faces matter; applying a fine finish to a whole part raises cost without adding function.
Yes. Clear and color anodize build a thin oxide layer, and hardcoat builds more. Threads and bores that must fit a mating part need masking or an allowance.
We check fits at DFM review and mask where needed. It is much cheaper to plan for this than to re-machine after coating.
Long parts are machined on the large-travel machines at 4,000 × 400 × 150 mm. At that length, temperature and clamping are the main variables.
We plan the setup so the part is supported along its length, and we inspect after the part has settled rather than straight off the machine.
A 3D CAD file plus a 2D drawing with tolerances, material, finish and quantity. STEP and IGES files work well.
If the drawing is incomplete we will still quote and mark the open points in the DFM analysis. That analysis comes back with the quotation, within 12 hours.
Yes. We sign an NDA on request, and uploads are handled as confidential. ISO 27001:2022 covers how we manage that information.
