FAQsTurbocharger Components for Automotive Industry Applications

Turbocharger parts include precision CNC machined components such as compressor housings with 1.5:1 to 4.0:1 pressure ratio optimized volutes, turbine housings with exhaust gas temperatures of 700 °C to 1050 °C, bearing cartridges with journal bearing clearances of 0.025 to 0.075 mm, and are capable of supporting shaft speeds of 250K RPM, center housings with 1 to 5 liters per minute oil passage flow rates, and actuator brackets with +5 degrees range of motion for wastegate control. Turbocharger parts include compressor and turbine wheels, shaft assemblies, and seal plates. Turbocharger parts demand bore concentricity of 0.010 mm, flange flatness of ±0.025 mm for perfect seal, dynamic balance to ISO G2.5 and thermal cycle range of ambient to 1000 °C.

Inconel 718 can handle very high temperatures and keep 1000 MPa tensile strength at 650°C, and turbine housings can resist oxidation up to 1050°C, and thermal fatigue where 100,000+ cycles is nothing, also won’t corrode from exhaust gases with sulfur and moisture. Stainless steel 304 and 316 is easier to machine and is more cost effective for things that don’t get really hot, while also have decent thermal resistance of 800C. Alu alloys such as 6061-T6 and 7075-T6 are really light, which cuts turbo inertia by 40 to 50%, have great thermal conductivity for dumping heat from compressor housing, can be machined really well, and can even handle boost pressures to 35 psi.

For journal bearings, we do multi-axis CNC turning, which gives us a diameter precision of ±0.005 mm, a surface quality of <0.4Ra microns, and a concentricity of 0.010 mm. 5-axis CNC milling for compressor housing volutes and turbine outlets achieves dimensional precision of ±0.025 mm. There is precision drilling for oil feed passages which achieves diameter control of ±0.020 mm and a straightness of 0.050 mm over 100 mm. The exhaust flange connections are done with class 2B thread milling for high temperature sealing. Wire EDM for cooling passages in turbine housings achieves ±0.010 mm which is really good. For gasket sealing, surface grinding on the flanges achieves a flatness of ±0.025 mm. Bearing bores are done with precision boring which has a diameter tolerance of ±0.008 mm. For dynamic balancing, we make sure the shaft assemblies are G2.5 (ISO) at the speeds they will be running.

As a turbocharger supplier who has been in the industry for over 10 years, we have had the ability to measure journal diameters to a tolerance of \u00b10.005 mm, major surface finishes to a tolerance of 0.4 Ra \u00b5m, oil film stability so that the bearing life exceeds 150,000 \u202fmi, bore concentricity to be \u00b10.010 mm so that shaft alignment and vibrations are kept in control, flange flatness to \u00b10.025 mm for prevention of exhaust and boost leaks, mounting holes positional tolerance of \u00b10.050 mm and oil passage diameters to \u00b10.020 mm for control of lubrication flows, formed threads to class 2B tolerances, and overall dimensional tolerances to \u00b10.050 mm. All these tolerances have allowed for turbocharger efficiencies of over 65% throughout the operational range, boost pressure stability of \u00b10.5 psi to the target, oil flow rates of \u00bf10 g/hr, shaft speeds of 250,000 RPM, and life over 150,000 \u202fmi/\u202f3,000 hours.

Yes, rapid prototype was developed based on CMM dimensional inspection 0.005µm on certian features, surface finish 0.05 Ra, concentricity by precision spindles, proper flow testing for aerodynamic verification, and material hardness. We do low-volume production for racing turbochargers and other specialized applications on 10-500 pcs yearly, and high-volume production for automotive OEMs. We provide turbocharger manufacturers with tiered volumes from hundreds up to low thousands annually. We provide concentricity verification and flatness verification on flanges, dynamic balances to ISO G2.5, and hightemp material certs. We supply turbocharger components with full documentation including dimensional certs and bearing surface documentation, concentricity verified, flange flatness measured, dynamic balance to ISO G2.5, material certs with high-temperature properties, and full Q docs to meet IATF 16949, ISO 9001, SAE J1826 and automotive turbocharger requirements.
