Applications

Turbocharger and compressor impellers
Marine propellers and pump rotors
Aerospace turbine rotors
Industrial fan and blower wheels

An impeller is where 5-axis machining stops being a luxury and becomes the only way. The blades curve in two directions at once, so a 3-axis tool either gouges the concave face or leaves a staircase on the convex one. We cut impellers and turbine rotors on simultaneous 5-axis machines with the tool tilting to stay normal to the surface, which keeps scallop height even and gives a real aerodynamic finish instead of a faceted approximation. Blades are balanced by holding thickness within tolerance across all blades of a set, and every rotor is inspected on a CMM before it leaves.

Key features

True simultaneous 5-axis, tool stays normal to surface
Even scallop height — no faceted approximation
Blade thickness held across the set for balance
Full machine simulation with collision check
CMM inspection report with every rotor

Scope of delivery

Foam-separated, individually boxed
Blade edges protected with caps
Balancing and CMM report enclosed
Export carton, palletised for sea freight

Quality control

Every batch is checked on a coordinate measuring machine, with calipers, micrometers and gauge blocks on the shop floor. A dimensional report is available with each shipment and first-article inspection is free on series orders.

Competitive advantages

vs. 3-axis shops (faceted impellers): True simultaneous 5-axis: tool stays normal to the surface, even scallop height, real aerodynamic finish
vs. Cast / forged impellers: No die or forging tooling; a 5-axis programme handles a prototype today and a 500-piece series next month
vs. Additive (SLM) impellers: CNC 7075-T6 / 17-4PH: no powder porosity, no build-direction anisotropy, surface finish for cavitation resistance
vs. Sheet-metal welded fan wheels: One-piece milled rotor, no weld distortion; balanced to G2.5 at your speed

Frequently asked questions

How do you ship, and who handles customs?

DHL/FedEx/UPS express for prototypes and small batches, sea or rail freight for production volumes. We ship EXW, FOB, CIF, DAP or DDP — with DDP the duties and taxes are settled on our side so nothing is owed at customs.

How do you protect my design?

We sign an NDA before you send anything sensitive. Drawings are stored on an access-controlled server and only the programmers and operators assigned to your part can open them.

What file formats do you accept?

STEP (.stp/.step) or IGES (.igs) for 3D, PDF or DWG for 2D drawings with tolerances and surface finish. If you only have a physical sample, we can reverse-engineer it — and a photo with the key dimensions is enough for a budget estimate.
