Seeking Recommendation on a Bench Grinder with Specific Features.

Vespel is definitely not a thermoplastic, and you definitely do not want to cut it with heat. I'd suspect the same with PEEK but I haven't tried that one.

I'd vote slitting saw. They get crazy thin.

Agreed, Bert. I've got a segmenting saw, but it only goes up to 300 RPM. I need something possibly ten times that fast.

Just be clear, Bert, are you talking about a CNC machine for the slitting? If so, I would have to job this out, which wouldm make our costs too high. I do have a CNC machine, but it is a small benchtop model with no water or coolant.

If you're referring to benchtop units, the industry standard is pretty much the Buehler Isomet line. However, the high-speed model I need is $4000-5000 for a clean used one, well beyond my means at this point.

If you have another specific saw or application in mind, I'd love to hear more.

Thank You,
Scott

I meant using a spindle from a CNC machine to make your own slitting machine. Something like this one:

(No experience with them, just searched "cnc spindle")

You'd need to make your own system, but you could stick a slitting saw into one of those mounted horizontally and make a small slitting machine.
