    Wire Vibration

    Dear All, I wish to thank you all for your comments, suggestions and advise. I've found the culprit! As simple as it may sound; but the problem was looking us at the eyes and we couldn't see it. It was a wheels misalignment problem. Our technicians were using basic alignment techniques, and a...

    TimeLord, How do you calculate the resonant frequencies of the wire, and how do we measure the frequency spectrum? Regards Husam

    Wire Vibration

    DesertFox, The outer rim of the pulleys are lined with an anti abrasion PU Layer (about 8mm wide X 12mm deep) that is grooved to provide a seating for the wire. The wire is already set to maximum tension. Though I'm not sure if it is slipping of not, HOW can I find out if it is?? Regards Husam

    Mike, Attached is sample pictures of the wheels for your reference. Note that the wheels become thicker towards the center. the bearings are mounted inside machine grooves to the exact size of the bearings OD. The drive motor is high torque 3 phase frequency driven motor. But what's your...

    Wire Vibration

    Guys, - DesertFox, the Wire is DRY. Almost clean and Not Slippery. - Mike, You absolutely right. It is a 2.5 Meter wide Wire Saw machine; but why would you expect it to resonate! - The Carriage that is shown in the sketch was merely symbolic. i.e. The system is much more sophisticated than...

    Wire Vibration

    Dear All, I believe I have a unique problem. To best describe it, I would request you to first have a good look at the attached sketch: - This machine runs a steel wire at about 3000 RPM. - The wire needs to continuously run WITHOUT any vibrations. - The Two green pulleys are mechanically...
