Machine vibration reduction
Machine vibration reduction
(OP)
I'm building a 20 hp abrasive lab saw. The frame is 60" x 72", made from 4"x4"x1/4" walled tubing. A pivoting saw assembly sits on a webbed riser on one corner and weighs 590 pounds - as much as the frame. I have some vibration in the frame that I would like to minimize the old fashion way through mass. Hypothetically, I could fill the tubing with concrete (very messy but will add stiffness) and more than double the weight. However, would plain sand accomplish the same thing by absorbing the vibration? I have no vibration analyses. The spindle and motor are adequatly ballanced. I'm looking for some simple tips in reducing vibration.
Thanks for your time,

Hi EvilKraut,
Have you thought about using a dynamic absorber ? Figure out the natural frequency of the system and attach a mass/spring system of the same natural frequency (but a lot smaller) underneath your frame.
Hope this helps
