key cabin Posted July 9, 2012 Report Share Posted July 9, 2012 Hi All, this may be a simple question with a simple answer but, everytime i put my universal 300 onto rotation engraving it vibrates very noisily, i have checked all the allen screws and they are all tight, is anyone else experiencing this or is it just unlucky me?

Gray Posted July 9, 2012 Report Share Posted July 9, 2012 Make sure the brass cutter knob isn't loose in the thread. Link to comment Share on other sites More sharing options...

markyboy101077 Posted July 9, 2012 Report Share Posted July 9, 2012 Afternoon Lower your Spindle speed from 20000rpm to 6000rpm Link to comment Share on other sites More sharing options...
key cabin Posted July 9, 2012 Author Report Share Posted July 9, 2012 it seems to be vibrating from the tensioner. Link to comment Share on other sites More sharing options...
Count Muppet Posted July 9, 2012 Report Share Posted July 9, 2012 I don't know this machine but on is200 it can vibrate when the motor belt starts wearing out Link to comment Share on other sites More sharing options...
StevenB Posted July 9, 2012 Report Share Posted July 9, 2012 Can you give us a photo of where you think the vibration is coming from? Link to comment Share on other sites More sharing options...
mrkeys Posted July 9, 2012 Report Share Posted July 9, 2012 Are you using a standard size cutter/drag diamond ? Or an extra long one ? I don't know this machine either but on our is200's if we put a longer drag diamond in then it sticks up at the top and "wobbles" when we turn the motor on. This makes a horrible noise like what you are describing. As soon as we go back to the standard sized drag diamond everything is all o.k. again. Might not be it but worth a try Link to comment Share on other sites More sharing options...
key cabin Posted July 10, 2012 Author Report Share Posted July 10, 2012 I have reduced the speed of the rotation and this seems to have rectified the problem for now, however a machine that costs £10, 000 should be as solid as a rock and not have to have the rotation turned down to silence it.

StevenB Posted July 10, 2012 Report Share Posted July 10, 2012 My best guess is that something somewhere has come loose & slowing down the spindle speed has just masked the problem. I've been using these machines for 10 years now & they are solid as a rock & well worth the money. Give U-Marq a call & I'm sure they will be able to help you.

Theone Posted July 11, 2012 Report Share Posted July 11, 2012 depending how old machine is or how much rotary engraving you have done it may be bearings in spindle, think you can send spindle back for a refurb or exchange Link to comment Share on other sites More sharing options...
