A classic style of transmission shaft is the key part of motor or turning unit. All transmission parts are running smoothly depend on the straightness, accuracy and hardness of center shaft. Sollwin keep the quality of transmission shaft by precise CNC machining which is including truning, milling, grinding and etc… All standard dimensions are control by ISO02768-f and key dimensions is allow to 0.01mm. Quenching and tempering is able to apply on different sections of shaft to reach various hardness in order to match speical requirements such like anti-seizure, wear endurance or service life.
