From passenger car compressor wheels to heavy-duty diesel turbine assemblies and performance racing rotors with advanced blade geometries, every component is engineered for maximum aerodynamic efficiency, thermal resistance, and reliable operation through 150,000 to 300,000 miles of automotive service.

We offer precision 5-axis CNC milling, which allows for the production of complex blade profiles and surfaces, precision turning for rotor shafts with a concentricity of 0.0002mm, dynamic balancing services compliant with ISO G2.5, as well as specialized surface treatments that inhibit both oxidation and thermal cycling. In addition, we offer flow bench testing and high-speed spin testing with a cutoff of 300,000 RPM. Every rotor in the turbocharger is milled from alloys such as 2618 and 7075 aluminum for compressor wheels. For turbines, the alloy Inconel 713 or 718 is used due to the need to withstand extreme temperatures. High-performing rotor wheels require titanium alloys such as Ti-6Al-4V, and for racing turbochargers, as well as extreme heat service turbochargers, specialty alloys like MAR-M247 and ceramic matrix composites are used. All these materials ensure a high compressive strength to weight ratio, thermal stability, and the mechanical reliability of the rotor in constant operation at RPMs of 80,000-300,000 and temperatures of 200-1050°C is accomplished.

FAQs: Turbocharged Rotary EnginesWhat is an automotive turbocharger rotor?

A turbocharger rotor is an assembly that rotates at high speeds and is an integral component of a turbocharger. A turbocharger is an aftermarket tool for gasoline, diesel, and hybrid vehicles that provides forced induction for power enhancement and increased fuel efficiency. Within a turbocharger rotor, there is a compressor wheel, a turbine wheel, and a rotor shaft. Turbochargers are typically operated between 80,000 and 300,000 RPM, with temperatures and service latencies that range from 200°C - 1050°C and 150,000 - 300,000 miles, respectively.

7075 aluminum alloys are most frequently chosen for compressor wheels because of their lightweight construct, ion that results in a rotational inertia and improved response. Inconel is chosen for turbine wheels because of its high strength and extremely good oxidation resistance at high temperatures. Titanium is also selected rapidly, due to its high strength-to-weight ratio.

For turbocharger rotors, there is a ±0.005mm dimensional accuracy for the blade profiles, a 0.002mm concentricity of the rotor shafts, and ±0.01mm blade angle tolerances, which is for aerodynamic optimization. There is a minimum surface finish achievable of 0.8 Ra in microns, which ensures the ideal surface for rapid and unrestricted flow, the most optimal dynamic balance is achieved, and ISO G2.5 is averaged.

Standard rotors take 18 to 26 days to complete 5-axis machining, heat treatment, and balancing. Custom performance rotors require 7 to 10 weeks. Prototype rotors can be finished in 12 to 18 days.

Certified components include IATF 16949 automotive quality, ISO G2.5 for dynamic balancing, turbocharger component specifications by SAE, and automotive industry endurance testing. Documentary evidence of high-speed testing, complete material certification, and balance sheets is provided.

Available is precision 5-axis machining, which results in an aerodynamic surface average on parts below 0.4 Ra microns, improving airflow, and is coupled with dynamic balancing to ISO G2.5 standards. Additional processes include coating of turbines with resonant thermal barrier shot peening encapsulation, and increased compressive fatigue resistance by 30-40%. Other included are ultra-smooth surface finishing to superfinishing, wear resistance from nitriding, thermal protection from ceramic coating, precision weak grinding to develop blade edges of specified angles of ±0.01mm, and thermal protection from ceramic coating.

Certainly. There are rotors designed specifically to meet particular boost levels and target performance profiles, including extreme performance racing wheels featuring custom blade profile geometry for optimal airflow and rapid turbo spool, durable rotors intended for heavy-duty diesel applications in over-the-road trucking, variable geometry turbine (VGT) wheels with mechanical blade actuation, compound turbocharger systems with precisely sequenced boost, electrically-assisted turbochargers with rotor-integrated high-output motors, and other features such as anti-surge capability, extended blade tips for increased adiabatic efficiency, low inertia design for reduced turbocharger spool lag, specific standard flow control trim sizes, and high-temperature material systems for continual operation above 1000 degrees Celsius.

When blades are machined with a tolerance of ±0.005 mm, the compressor efficiency increases by 3% - 5% and the turbine efficiency increases by 2% - 4% and the turbocharger is more fuel efficient with lower emissions, as the aerodynamic efficiency is increased. Maintaining a balanced dynamic configuration to the standard of ISO G2.5 removes the risk of the turbocharger bearings wearing out, as vibrating at high speeds is eliminated and the life span of the turbocharger is increased to more than 200,000 miles. A controlled surface finish better than 0.8 Ra microns improves airflow by decreasing friction and heat loss, which improves efficiency. Using llightweightaluminum decreases turbo lag by 15% - 20% and high performance Inconel is used at increased temperatures. 5-axis machining is of high quality, which vastly improves blade geometry and fosters new design. Complex geometry improves the flow of the turbocharger and increases the surge margin. The precise machining of turbocharger components promotes a new standard in turbocharger production, allowing reliable operation in a wide variety of applications ranging from passenger cars to diesel trucks. In fuel-efficient passenger cars, improved fuel economy and performance are achieved. In trucks, improved torque delivery and efficiency are achieved. In performance vehicles, quick throttle response and maximum power output are facilitated, and in racing applications, extreme boost levels exceeding 30 psi are achieved with 150,000 - 300,000-mile service life for improved forced induction and fuel efficiency. Engine reliability is improved.
