What are the steps of impeller & turbine processing?

custom Impeller

An impeller is a rotor inside a tube or conduct used to increase (or decrease in case of turbines) the pressure and flow of a fluid. Impeller is the heart of turbocharger. Impeller is on turbocharger’s rotor, it has very complicated structure. When turbocharger operates, impeller will press as much purified air into the cylinder, transform into kinetic energy to improve the engine output. During the process, impeller spins fast, and the tangential speed of rim is fast. The flow situation in the impeller is complicated, and usually under high temperature, high pressure and corrosive environment. Integral impeller design and quality have a crucial impact on the turbocharger’s performance. Despite a practical design, machining precision and technical requirement is important as well.

Five Axis Machining for Impeller

At present, a 5-axis CNC machining center is the only method to solve the machining of the impeller, blade, Marine propeller, heavy generator rotor, turbine rotor, large diesel engine crankshaft and so on.

The additional movement available with 5-axis machining allows you to achieve complex shapes and designs, 5-axis technology completes the impeller in a single setup. turbocharger 5 axis cnc machining center.

Tighter tolerances specified

These turbocharger Impeller are manufactured from 5 axis machining center, heat resistant materials to within ±0.002" tolerances, then laser marked, assembled, and quality checked in accordance with ISO9001.

Custom Turbocharger Impeller

For Custom CNC Machining Turbocharger Impeller, the manufacture of complex rotational parts with multiple blades, such as blisks and impellers, as well as individual blades, require complex 5 axis milling. Tik precision offers its own impeller/blisk and turbine package for components used in aircraft engines, turbomachinery and power generators.
●Tik precision engineers have extensive experience and knowledge of vane grinding through direct involvement on bespoke customer projects.
●5-axis machining has featured in high efficiency and high precision; Single setup helps save time and money.
●standard tolerance of components is +/- 0.005 inches, and tighter tolerances can be discussed
●For turbocharger impeller grinding, the work piece is made from a high temperature resistance alloy, which makes it difficult to grind.
●Tik Precision are experts at customizing this precision grinding process to suit your needs.
●5-axis machining helps create surfaces with a quality finish.

To achieved the high technical requirements, we will encounter some problem during the machining.

Turbocharger impeller is high-speed running in practice, to prevent the vibration and noise. It raised requirements for the machine and cutting tool, we need to save process time and ensure the stationarity and symmetry.

How does Tik precision produce a turbocharger impeller?

It required very precise for the production of turbocharger impeller from the 3D drawing to finished product. For a turbocharger impeller to operate correctly, it is quite essential to know clearly about the operation of the turbocharger.

3D mold design

3D model is created by the help of commercial software. Our engineers reviewed, identified, and actions for improvement documented during Pre-production meeting for critical quality and safety

Processing scheme of impeller

Confirm the processing scheme of blades. Make the production order and send it to the production department by production management system.

Finishing and Post-processing

Use the 5 axis high precision machining center for the processing of the turbocharger impeller, and finish post processing by postprocessor
