Hi! Further to my problem of finding a suitable milling wax… I
am using a programmable engraving machine which is designed for
making routed plastic signs. Quite some time ago it occured to me
that with the proper tooling it could also double as a programmable
milling machine. I drilled the end of one of the engraving tools and
inserted a high speed drill shaft and brazed it to the tool. I turned
the drill down and ground it until I had a crude end mill. The system
worked and since then I have made many sizes of cutters. My problem
occurs when I am trying to cut very small lettering into the top of a
wax ring top. My cutters are as small as 0.20 mm. diameter. Some of
the lettering is barely over a millimeter in height. The cutter cuts
the letters finely but the cuttings are not ejected. The only sure
way I have found to remove them is to soak the work in epoxy and pull
the epoxy off along with the cuttings before the epoxy is
completely hard. Usually more than the cuttings are pulled off and
the pattern is damaged. I have produced beautiful school rings and
pendants but I don?t dare take a large order because my system is
still ?experimental? I was hoping that there was a special wax for
this type of work. Dental supply houses have milling wax but it?s
sold in 25 gram lots. That is too small for what I have in mind. I?ve
tryed both the green and blue waxes but both have the same problem.
Probably I could solve the problem if I had factory-made cutters.
Anybody know where I could get cutters made on a 11/64 th shank with
the cutting head as small as 0.2 mm. ?
