CNC Machined Powertrain Housings for Automotive Teams
Powertrain teams in Ann Arbor need housings with precise bearing bores, flat mating surfaces, and zero porosity. We machine aluminum and iron powertrain housings to ±0.0001" on critical bores. CMM inspection and material certs on every order.
Powertrain Materials
Aluminum, ductile iron, and gray iron with material certs.
Bearing Bore Precision
±0.0001" on critical bearing and journal bores.
QC Docs
CMM inspection reports on every powertrain housing order.
University Town Drives Automotive R&D and Connected-Vehicle Innovation
Ann Arbor is the brain of Michigan's auto industry — the University of Michigan's Mcity autonomous-vehicle test facility, Toyota Research Institute's Ann Arbor office, and a dense cluster of mobility startups make the city a hub for connected and autonomous vehicle development. Tier 1 suppliers including Bosch, Continental, and Hella maintain engineering offices, while legacy machining shops across Washtenaw County serve prototype and production programs.
RivCut supports Ann Arbor automotive teams with rapid prototyping, production machining, and the dimensional precision your AV and EV R&D programs demand.
