Before writing his landmark books, Wowk gained extensive field experience in machinery diagnostics and corrective techniques. He is an instructor for both in-plant and public Machinery Vibration Workshops, making him a trusted educator in the field. His reputation is such that when professionals discuss balancing formulas, they often point to his writings as the authoritative source. He is the author of three major works published by McGraw-Hill:
The most widely adopted standard for rigid rotors is . It defines Balance Quality Grades (G), from G0.4 (for precision spindles) to G4000 (for slow-turning marine diesel shafts). The required Balance Grade (G) is determined by the machine type and its intended purpose. For example, a high-speed turbine requires a much higher balance quality (a lower G number) than a heavy industrial fan. It is important to note that ISO 1940-1 has been technically replaced by ISO 21940-11 , though the fundamental principles and grades remain largely the same. machinery vibration balancing victor wowk pdf
