Solide arborite, 3/8" thick

Post by DanFecteau »

I post a message on the thermwood forum but nobody answer to this, I have to machine app. 20000 ft of solide 3/8" arborite and can't find the best way to do it. Right now I tried a courmatt # cu-375-4sh wich is a 3/8" x 1-1/8" x 3/8" x 3" up cut slow helix. Quality of the cut is good but after one 4' x 8' sheet the tool is dull and burned. My feed was app. 200 ipm and rmp between 14 000 and 15 000. I used an onion skin because all the parts are 2 1/4" wide. I really need advice for this because it's a huge project for us and it will begin soon. I have to deliver prototypes right now so I'm doing some testing....Thank you very much for your help.

Hi Dan,

I will have someone reply to your post early next week. We used to machine this for our table tops so we should have some specs for you to try.

thanks,

That's great news ! The thing is that in one 4' x 8' sheet I have approximatly 50 pieces of 2 1/4" x 30" (average). So I understand that it's not the same thing than machining 2 table top a sheet, so I do not expect the tool to last 40 sheets but I would like to optimize.

Thanks for your help.

Hi Dan,

If Arborite is the same as Arboron then Lynn at Vortex gave us this suggestion.

"In that case we have re-designed our series 6100 & 6200 to more of an o’flute geometry  and without chipbreakers which works very well in the phenolics.  The 5800 series also works well.  We ran the 5853 in some ¾” phenolic here at our facility at 16,000 @ 320 ipm.  We ran this in two passes.  Left a beautiful finish."

Let me know if this works.

Thank you very much. I think I will try the 6140, I think the chip breaker will be helpful and if the finish is not that good I will sand it a little bit. I will still use onion skin and might finish it with a downcut (regular) just to be sure parts hold down. Right now I was using courmatt CU-375-4SH wich I think is a similar tool but without the chipbreaker. Finish was good but the tool last only one sheet (many parts in the sheet !!)
