frazing machines

[pipeguy]

Hi all does anyone know who produces frazing machines??? Just curious ,I can't find anything on the internet Thanx Bob Clark

No one.

They're all likely custom jobs from custom
plans. Jorn Larsen designed and built one or more, but outside of France or Italy, I'm not sure you'll have much luck with help. Try contacting some
of the older American factories to see what they have sitting around as scrap.

Ok, I'll be the guy to ask the question for what I assume is many others...

What the crap is a frazzing machine? Sounds...dirty.

[KurtHuhn]

It's actually spelled "Fraising" Machine.

It a machine onto which you mount a master, and it replicates several more using hte master as a pattern. How the actual machine cuts is up to the designer of the machine. Some use blades like circular saws, others use specialty cutters, and other use what appear to be ball-nose end mills. However they actually cut, they are reproducing the master mechanically, without the aid of CNC, CAM, or other modern marvels. If you look at the thread started by Fred concerning the pantograph, they operate similarly, except in three dimensions instead of just two.

Isn't that a revolver lathe?

I don't know what that is, but I'd like to have one.

Rad

no doubt, but if I had one I think i'd feel like a cheater or something.

[bikedoctor]

Interesting.

Does the craftsman lose a "connection" with their output when automation is introduced? Does the craftsman lose some artisanship?

[Leus]

That's subjective.

However, the revolver lathe shown above isn't an automated machine, its operated just like any regular metal lathe. So the curved surfaces that guy creates are done by twisting two handles, and I would say that needs great skill.

The main objective of a revolver lathe is not to have to mess around changing tools. Handy, that.

[KurtHuhn]

That's a lathe, yes. And I think Leo is right about it being a revolver lathe. Those aren't too common in the U.S. You can get similar functionality from a QC toolpoost on a metal lathe, but it's a lot more fiddly. Revolver lathes use big handwheels or levers to manipulate the X-Y movement of the cutting bits, and the movement is fairly quick.

I want one.

[Leus]

I want one.

Oh yessss. Me too.

Enough tool porn for today.

[FredS]

The machine in the video is commonly known as a turret lathe in the US (I ran one in a job shop making gun parts when I was 18). As Leus says, it still takes plenty of manual skills, it just makes tool changes between operations much faster (after the initial setup).

I want to know how he drills all of those stummels without doing any measuring.

Rad

x-ray vision.

or, some type of marker on the side that shows when the bit is X distance from the back of the chuck.

Rad

Most likely he has set up some a stopper for the carriage and an indicator (probably a mark on the jaws) where the drill will stop.

Are you thinking of getting one, Rad? You'll end up making around ninetysomething bajillion pipes a month that way!
