Hi - sorry, first post and quick intro... Working in powergen field, ME background, Field Engineer, and now working in contract management ... not pretending to be a machinist although I understand some of the techniques and such.
Here's the situation. I am on the freakin' Hawaiian island of Oahu. I have a fairly large casing with 22 holes. I need to have some spot faces cut into the bolt holes for a spacer to sit. Given the setup, we had to flip the casing to be able to get a magbase drill over the hole center. We're currently using the magbase with a morse taper and custom made cutter blades (2 blades opposite). We're having to cut into the case, which is Inconel, to a depth of about 3mm. The spotfaces are 43mm in diameter. Since, the drill is mounted on the upside-down flange of the casing, the shank drops through the hole, and the drill is pulling upwards to apply pressure to cutting surface. Of course, with the morse taper, this is not ideal.
I've done quite a bit of researching for back spotfacing tools made out of carbide, but it seems that the ideal fix is a complicated tooling setup designed for automated shop work and not a field application. However, that is why I'm posting here to see if someone more knowledgeable than I knows of a setup that would work.
I'm also trying to see if I could get a portable, hydraulic Lamina mag setup. But, time is money, and I've got a time clock running to finish this work, rebuild, and start the unit before we get into some serious liquidated damages.
Looking for miracles...
