[Input shaft]
CVT parts for small vehicles.

The whole process, from material input to turning, rolling, finishing, and 100% inspection, is automated.
Special rolling dies are used to roll unique spline forms (various specifications).
To achieve accurate precision when controlling the outer diameter polishing dimensions, the first product after grinding stone dressing has an automated removal feature that detects dimensional abnormalities early.
We guarantee 100% main dimensions using our own in-house inspection machine.
