Hi, Everyone. I’m a raw newbie here, so please forgive me if I ask some really silly or uninformed questions. I will finally have some time during the holidays to start using my machine. I have a Shapeoko 4, all set up and ready to go.
First question. I make very expensive guitar picks, ranging in price, for one pick, from $40 to $99 each. These are made from engineering plastics such as Ultem, PEEK, DuPont Vespel, and the like. Although so far I have not cut these materials with a CNC, in my experience they cut, sand and grind very similarly to Delrin, Acrylic, PE, etc.
I need to buy a basic combination set of entry-level bits. I don’t necessarily want to buy the cheapest stuff out there, but I also don’t want to buy Snap-On bits. From the little I know, I believe the kind of bits I’m seeking would be called End Mills, correct? Right now, I’m looking at this set. Is this a good place to start?
For my initial jobs, I will never be cutting anything thicker than .080" (2 mm). Therefore, because my materials are so very expensive, to minimize material loss I would like to work with the thinnest possible bits that won’t break. (To give you an idea of my material expenses, a 12" x 12" x .060" square of PEEK can sell for upwards of $300.) I am thinking initially of trying to cut with a 1/32" bit.
Is it possible that I can go with a bit thinner than 1/32"? If so, what bits might you recommend?
Suggestions accompanied by direct URL links would be a huge help.
