This paper presents a method for assessing radial and axial error motions of spindles. It uses the Hewlett Packard 5529A laser interferometer. The measurement is made using reflection directly from a high-precision sphere. ...

The spindle of machining centers must provide high rotational speed, transfer torque and power to the cutting tool during continuous periods of time. The constant forces generate faults in its components where the most ...

The present work compare two methods of alignment of rotating machinery. The alignment by dial indicator and the laser alignment user to reduce vibration in equipment. Two dial indicators are used for measuring the relative ...

Machine tool vibrations are one of the most important factors affecting surface quality of machined components. As a consequence of high level vibrations, the costs associated with subsequent finishing operations are usually ...
