Building on the Right Foundations : Modern Machine Shop
Building on the Right Foundations One of the largest vertical turning and milling centers in the country will be installed in this Cincinnatiarea job shop. Although installing the foundation for this huge machine was a massive undertaking, the company is building on other "foundations" as well.
ASME BOOKS Passive Vibration Isolation
Vibration isolation is a vibration control technique in which the source of vibration excitation and the object to be protected are separated by an auxiliary system comprising special devices called vibration isolators or vibration isolating mounts.
