5-Axis CNC Machined Open Impeller Blisk, High Precision Custom Part for Aerospace Engine Compressor

This custom impeller rotor is manufactured by 5-axis CNC precision machining, designed for fluid power, vacuum equipment, hydraulic systems and engineering machinery. We support a wide selection of metal materials, complex curved profile machining, good dynamic balance performance and strict surface finish control. It can be customized per your drawing, 3D model or sample requirements.

✅ Highlight Note: Unlike casting impellers, our fully CNC-machined rotor has no internal porosity or shrinkage cavity, which improves reliability under high-speed rotation & pressure cycling.

We provide diversified material solutions to match different working conditions:

1. Aluminum Alloy 6061 / 7075 Light weight, good thermal conductivity, easy for anodizing, excellent machinability.

   📌 Annotation: Suitable for high-speed rotating parts to reduce centrifugal load, widely used for low-medium pressure fluid & air power equipment.

2. Stainless Steel 304 / 316L Outstanding corrosion resistance, acid & alkali resistant, suitable for humid, liquid, chemical medium environment.

   📌 Annotation: 316L is preferred for water pump and corrosive fluid working scene.

3. Titanium Alloy TC4 High strength-to-weight ratio, corrosion resistant, high temperature resistance.

   📌 Annotation: Premium option for high-end fluid equipment, suitable for demanding working condition.

4. Brass / Alloy Steel Brass: Good wear resistance & self-lubrication; Alloy steel: High structural strength, wear-resistant after heat treatment.

1. 5-axis simultaneous machining Complex twisted blade curved surface is finished in one clamping. No secondary positioning error, smooth blade flow channel, small flow resistance.

   📌 Annotation: Cast impellers cannot achieve such precise and smooth blade profile.

2. Strict burr-free control Manual & CNC deburring for blade root transition, avoid turbulence and particle falling off during operation. Critical for clean fluid & vacuum systems.
3. High dynamic balance capability We support dynamic balance testing and correction to reduce vibration, noise and extend bearing service life.
4. 100% dimension inspection before delivery CMM / 2.5D projector inspection for key dimension, report can be provided on request.
5. Full customization service Modify blade angle, thickness, diameter, bore size according to your hydraulic performance simulation data.

✅ Hydraulic pumps & fluid manifold systems ✅ Vacuum equipment, industrial fluid modules ✅ Engineering machinery power components ✅ Air blower, turbo fan & turbine power assembly ✅ Medical fluid transfer equipment ✅ New energy cooling circulation system

📌 Annotation: This rotor fits outsourcing demand for industrial fluid systems.

A: Yes. We accept STEP, IGES, STL, DWG, DXF drawings and physical samples. Our engineering team will review manufacturability and provide DFM feedback before production.

A: We suggest 316L stainless steel or TC4 titanium alloy. 316L is cost-effective for most weak corrosive fluid; TC4 is selected for strong corrosion and high temperature occasions.

A: No strict MOQ, we support prototype single piece trial order and mass production. Prototype lead time: 7–12 working days; Mass order: 15–25 working days, depends on material & surface treatment.

A: Yes. We can supply dimension inspection report, material certificate, dynamic balance report and heat treatment document if required.

A: Yes. Options include sandblasting, wire brushing, hard anodizing, passivation, electropolishing. We will recommend proper finish matching your material and application.
