    Question Cutting Teflon, Grilon, Nylon and similar?

    Im cutting a piece of grilon and the dwarf is giving me a hard time, no matter what I do it keeps accumulating and forming solid plastic pieces:



    I think the solution is to refrigerate the piece while cutting, but I cant use fluids since my machine is not waterproof.

    Suggestions? :drowning: Thanks

    Cutting Plastics

    Use a new, never touched any other material, cutter with a strong helix to pull the chips up out of your hole.

    Try to keep the speed down below 5000 rpm.

    Take at least 0.01" (0.25mm) per tooth cut.

    You want a good sized chip at a lowish speed to carry all the cutting heat away with the chip.

    Peu -

    Too much heat.....if your chips are melting, slow down everything except feed.

    That shadow down by the end of the spindle in your design needs to be designed out - it's gonna make it hard to see smaller cutters....

    Here is the finished part:



    the imperfections you see were due to the 1st cuts, then everything went smooth, routed both circles and cutted top and bottom, sides where left untouched.

    Thanks

    now to update my log
