ROTEST
ROTEST, device to measure shape deviations of the bearing balls circularity, sinuosity, roughness.
It serves for measuring and evaluating the shape deviations of the bearing balls in the range of diameter 2 - 40 mm. It is designed for quick verification of variations in circularity, sinuosity and roughness in a selected cut of the bearing ball.
The device is placed on a sufficiently rigid desk.
Main parts:
- mechanical part - stand, precise spindle, set of 5 conical bearings, set of carriers of rotary movement,
- electrical part - electronical assessment unit with a processor, noise 8pm (picometres), program to evaluate deviations in circularity, sinuosity and roughness Roform, computer, inductive sensor, printer.
