| John Lindo:
I had to reduce a piece of MDF board thickness the other day. Using my mill and a standard endmill it worked ok,until I picked up my shop vac with a plastic hose to clean up the DUST and at the same time touched the machine. I got quite an electrostatic shock. It's never happened before,with metal cutting so I did a bit more cutting and again same thing happened. Is the MDF storing static? John Spain |
| Bluechip:
John Does happen, I get it with machining plastic. Bits jump up and stick to the side of the nozzle rather than going up the tube. Never got a shock yet but it certainly could happen. You've just made a rather crude but nonetheless effective 'Tribo-electric' generator with the dry dust and the insulated hose. http://en.wikipedia.org/wiki/Electrostatic_generator Dave |
| DMIOM:
hi John, just a couple of thoughts : 1/ Try and avoid inhaling the MDF dust - the dust, and (if present) the formaldehyde binder aren't good for you (MDF health FAQ) 2/ Re dust / electrostatics - wood dust (= fine particles) is explosive, and commercial extraction systems have to be conductive so any static is dissipated to earth (useful info) Dave |
