Cutting Thin Brass Tube

Too bad you didn't think to ask while you were there. I'd be interested in hearing the answer too. Maybe a machine that deburs right afterwards?

--I cut it with a wet abrasive cutoff saw. Leaves very little in the way of burrs, but does leave a little. In a manufacturing operation this could be down to a science and the burr all but eliminated.

I did, but the cutoff mechanism was out of sight, buried deep in the machine and the operator didn't have a clue (nor did he seem to care).

If I was running that machine I would have to know intricate details like that. I'm just too curious.

It may have been done by a flying rotary cutoff. That could be a slitter or slotting blade that travels diagonally for a distance at the speed of outfeed, making it's cutoff, then drops down and returns to the starting point by the time the next cut spot gets to it.

Many years (35) ago I worked for a steel tube manufacturer. One of the cut off machines used two blades the fist had a 30 deg. bevel which took a slice from the top of the tube. The second blade came down into the opening with a 60 deg. point to complete the cut. AFAIK these blades were of high speed steel perhaps 0.100" thick and sharpened at 90 deg. and no clearance. The night I worked on this machine, the operator and I cut, flared, inspected and packed something like seven thousand pieces of 1 1/2" tube about 8" long in about six hours. I seem to recall that this tube was something special in that it was made of two layers or something. I do remember that it was a very busy night but the production bonus rate was very good.

Drives me nutz.... I, myself, just gotta know how stuff works. Employees today "don't know nothin', don't wanna know nothin', ain't gonna learn nothin', where's my paycheck and how come it's so small?" Ken.
