Can anyone recommend starting points for feeds and speeds in machining durastone pallet material using a CNC routertable? Cutter suggestions as well.

I would recommend getting someone else to do it, like a specialist (Global Datum or other), as it makes a frightful mess. The world is littered with machine shops that have machined Durastone once.

From my notes ... "Durastone is some of the nastiest material i have ever worked with, first of all i will suggest using a mask and long sleeve shirts and don't do anything to try to get the fiber glass out of your body... take a cold shower and slee

Agreed. We machine all our pallets in coolant. No dust but a big mess still results in the bottom of the CNC. You'll burn through a thousand cutters if you try it on a router table. Just doesn't seem feasible. You'd have to take like 0.020" dept

We used durastone, with a profile routed out to expose certain areas & protect others. Durastone costs peanuts, and the tool room uses a small cheap Micromat router.

Hi Ken, There may be different composites of Durastone, but there are certainly mixes out there that are. http://www.ascenteceng.com/resources/materials.html We used durastone as a carrier for flex circuits as well. Cheers, Rob.

For volume we used machined pocket durastone pallets, machined to the thickness of the flex to allow flat printing, with pockets machined for components placed on side 1. We held them down with 3M spray mount. For low volumes we used flat durastone

The opening in the wave pallet for the TH connection in question would be a titanium insert rather than just a cutout in the durastone like normal. They're able to hold tighter tolerances with the titanium vs durastone as far as I understand.

I don't think durastone is ESD safe.

I thought durastone was not ESD safe?
