  How to shortlist and qualify a 5-axis supplier

Every machine that tilts a table gets marketed as 5-axis. The distinction that changes your part cost is whether all five axes move at the same time while the tool is in the cut. On a simultaneous machine the tool tip follows a continuous path across a contoured surface. On a 3+2 machine the table indexes to a new angle, locks, and cuts. Two setups become one, but the surface is still faceted between index positions.

That difference shows up in three places. Impeller blades, turbine housings, and bone-screw threads need simultaneous motion because a locked table cannot reach the undercut. Bracket faces, bolt-hole patterns, and pocket floors are fine on 3+2 and often cost less per part. If a supplier quotes a contoured surface but plans it on a positional machine, expect hand blending or a polishing step that was not in the price.

There is a third path worth knowing. Mill-turn centers combine a rotating tool spindle with a turning axis, so a shaft with cross-drilled holes and milled flats comes off in one cycle. For parts that are mostly cylindrical with a few milled features, that beats a pure 5-axis mill on cycle time and on concentricity.

Ask one question to settle it: which machine, by model, will run my part? A supplier who answers with a specific spindle and a specific table size has already done the process planning. A supplier who answers with a brochure has not.

Travel size is the second filter, and it is where most suppliers overstate what they can hold. A Ø400 mm rotary table with a 500 × 500 × 450 mm envelope handles a compact housing or a medical implant. A 750 × 1,150 × 550 mm envelope covers a large automotive fixture plate. A 4,000 × 400 × 150 mm gantry travel is what you need for a long structural beam or an extrusion profile.

The mistake is quoting a long part on a small machine and then adding a second setup to reach the far end. Every extra setup adds locating error and fixture cost. On a ±0.005 mm feature, a second setup can eat the whole tolerance before the tool touches metal.

Kinematics matter too. A trunnion table swings the part; a gantry moves the spindle over a fixed bed. Trunnion machines are faster on small, light parts. Gantry machines hold heavy parts without the table sagging under load. Neither is better in general. The part decides.

One practical check: ask for the maximum part weight the rotary table is rated for, not just the travel. A 300 kg fixture on a table rated for 150 kg will deflect, and no amount of tool-path smoothing fixes that.

A tolerance claim without a feature type is marketing. ±0.005 mm on a 20 mm bore in aluminium is routine. The same number on a 600 mm titanium frame is a different problem, because thermal drift and tool deflection scale with part size. Ask for the tolerance on a feature of your size, in your alloy.

Surface finish behaves the same way. Ra 0.2–0.8 μm is a fine finish that usually needs a dedicated finishing pass or a polishing step. Ra 0.8–1.6 μm is a high finish that comes off the machine on most aluminium and stainless grades. Ra 1.6–3.2 μm is as-machined and is the right call for a bracket that will be painted. Specifying a finer finish than the drawing needs is one of the easiest ways to add cost.

Inspection evidence is the tiebreaker. A supplier that checks raw material on arrival, monitors in process, and inspects 100% before shipment can hand you a report for the features that matter. Ask what the report covers and whether it is included or billed separately.

For prototype runs, the finish number also decides the process. If your drawing calls for Ra 0.4 μm on an internal channel, a 5-axis mill may not reach it and the part will need abrasive flow or hand polishing. Better to know that at quote time than at first article.

Certifications are not decoration. They define which industries will let you bid. ISO 9001:2015 is the baseline for process control and traceability. IATF 16949:2016 is what automotive and EV programs require before they will release a drawing. ISO 13485:2016 covers medical devices. ISO 27001:2022 covers information security, which matters when you send CAD files to an outside shop.

Ask for the current scope statement, not the certificate PDF. A shop can hold ISO 9001 for machining while the process you need, say heat-treat or anodizing, sits outside the audited scope.

Capacity is the other half. A shop running 16 simultaneous 5-axis centers plus 12 four-axis mills, 27 three-axis machines, and 16 mill-turn centers across 127 high-precision CNC machines can absorb a schedule spike. A shop with two 5-axis machines cannot, no matter what its website says. Machine count is not a vanity metric. It is the reason a date holds or slips.

Floor space and headcount tell you whether the shop owns its process. 7,600 m² across three wholly-owned plants and 150 technicians means inspection, finishing, and assembly can stay in house. Every operation you outsource to a third party is a handoff where traceability and schedule control get weaker.

Quote speed is a proxy for process maturity. A shop that returns a price and a DFM note within 12 hours has read your model, flagged the thin walls and the deep pockets, and picked a machine. A shop that takes a week is usually guessing. The DFM note is the valuable part. It tells you whether the quote is real.

MOQ is the next trap. Shops that require 100 pieces to start make it expensive to validate a design. No minimum order quantity, from one prototype to 10,000+ part runs, lets you qualify the process on a single part and then scale on the same setup. That is how you find out whether the ±0.005 mm claim holds before you commit to a production order.

Do not read a lead time as a promise. What matters is the historical distribution. A shop whose late-delivery probability sits below 2% is planning capacity, not quoting hope. Ask how the number was measured and over what period.

Confidentiality belongs in the same conversation. Uploads that stay secure and an NDA available on request are the minimum for anyone sending proprietary geometry. If the shop cannot describe how files are stored and who can open them, keep looking.
