Workshop Overview
This course is an intensive mix of hands-on practice and in-depth instruction of precision shaft alignment and balancing of rotating machinery. It provides a very good understanding of the theory and practical knowledge in conventional and laser alignment techniques as well as both field balancing and shop (balancing machine) balancing.
Duration: 3 Days (1.5 days alignment & 1.5 days balancing)
