[Accumulator body]
Transmission part, cup-shaped casting automotive part.
The cylindricity and surface roughness of the thin-walled cylinder's inner diameter need extremely difficult processing, yet our unique processing technology has enabled mass manufacturing.
Furthermore, employing an in-house built 100% cylindricity inspection machine, we can ensure complete correctness.
Measurement results can be archived as graph data.
