Using tooling after a FIRE3/16
We had a massive fire at our shop and it burned EVERYTHING combustible in our shop, even burned the paint off our carbide shaper tooling INside some metal cabinets. The carbide is still attached to the molding heads - i.e. did not melt off the brazing.
Can we clean these up and run them on our shaper?
it would sure be nice to have one less expense in our rebuild.
Hey, what's the worst that could happen?
Our original shop was a total loss in the 80's from a fire.
We did go in and salvage some shaper tooling, all brazed carbide - and continue to use it even today. Carbide doesnt lose its ability to cut in heat, as long as the brazing is still intact you should be fine.
Would make sense to send to a tooling shop for a once over, maybe a sharpening.
Sorry to hear about your loss, it is a horrible event to have to go through.
So in this post you're asking for opinions please keep in mind that's only what I am giving here.
1- Safety, It's easy for others to say use the tooling you will be fine, you very well may be fine using it....but they are not the one standing behind the tooling when it is spinning at high rpms, if you hit a knot in a piece of wood and the tooling has stress cracks from the fire ask yourself how you would you feel if someone got injured?
2- What temperature did that tooling get to in the fire is unknown other than it did not melt the brazing, it could have stress cracks in it after dousing it with cold water in the firefighting efforts, it could be warped or the bore diameter could also be altered.
That's just my opinion
Good luck to you
I would have to agree with Russ, use the insurance if possible. Silver braze alloy melts at 1100 to 1200 deg's so you should see signs of that if it got that hot. The cracks that maybe in the carbide would be my biggest concern. I would at least send to a sharpening shop to be cleaned up and sharpened. I would also tell them what happened so they can look at them closer than usual. If the insurance covers it, then I would use it also. These cutters are turning and in a bad height position for the male body if a tip comes out. Sorry to hear about the fire.
I agree with the past firefighter, although I have no idea what that is, nor what "rpms" stands for, but the risk of using any tooling that has been subjected to uncontrolled heating and cooling is just too great. This business can be dangerous enough without increasing the danger due to cheapness.
Get new tooling.
