Cutting G10 material without metal tools? (CNC milling)

[burnthills]

Is there any way to cut G10 material ( http://www1.mscdirect.com/MSDS/MSDS0...8-20040908.PDF ) without using metal tools? I have an order from a company that does MRI & Electromagnetic processes - they cannot have any metal fragments imbedded into the material. Any advice/tips would be appreciated.

a cutting tool isn't going to leave metal in the G10,none to speak of anyway. The only other way i would think you could do it would be waterjet or laser without using a metal tool. Unless you used a diamond tool.

I suggest you get some quantification on 'they cannot have any metal fragments imbedded'. If their requirements are so low that it is necessary to worry about wear particles from the tooling then you might have to worry about metal dust settling on the material and getting imbedded just from handling.

hello On this forum very be glad

is this just a 2d cut if so water jet is great, but may leave some garnnet embeded you would have to just give it a try.

we cut plastics and composit all the time on our waterjet.

Thank you all for your suggestions.

The problem with using waterjet is some work on it cannot be done in 2D machining. The kit of parts includes parts that have square keyways in them, something that can only be cut with an end mill. If that wasn't bad enough, there are 4-40 and 8-32 threaded holes that are required (one solution for that may be counterboring the locations and press-fitting stainless steel threaded inserts).

After more research, I've found some suppliers that sell ceramic inserts, (diamond would perhaps work as well) such as: http://www.greenleafcorporation.com/

If we go through with the work order, I will update our results.
