My boss has given me the project of building a barrel vibratory machine for some large parts (WHY ME I HAVE NO ******* IDEA(BUT COULD BE FUN)).

I have read through all threads posted on this subject... but iam concerned about a few things. First being the machine will have to be ~ 24" X 24" X 12' and with media and all about 8,000 lbs.

:wee:


Supporting this monster and being able to vibrate WITHOUT destroying everything around it will require some tuff springs, I am thinking around 20 old car qoil springs.

And secound, one type of part that we need to deburr is 'L' shaped aluminum machined down in many places 0.060 thick.

Will a machine that large distroy something that small?!?!?!?!? Any ideas you guys can give me would be greatly apreceated. This may be a dumb idea but the alternitive is to spend $20,000 on a new machine.

Thanks

CAN YOU BELIVE IT THE DARN THING WORKS!!!! :)

Well it took some time and the monster's weight is about 2,000 lbs more than what i thought. but it work and works well. When I can get to it I will post a pic.

I'm excited to see the pics!

Holy cow! 10,000 lbs? This I gotta see.

What kinda operation are you runnin? Carwash? 10,000 lbs? Lemme guess.... Cast-iron? Tandem pistons? Cummins turbo diesel?

I'd just like to discuss the safety features of your device.

Pic's must have pic's I think it's in the bylaws or somthing I think !!!! Kevin

No pics? It doesn't exist...

The safety feature is STAY THE HELL AWAY!!

We added a few supports to keep it from tiping side to side, and twisting. But other than that its not to bad. Belive it or not it dose jump up and down on the floor, getting a concrete pad with anchors ready for it now.

Anyway sorry for the delay here are the pics!

Ugly... but it dose the job

WOW!! :eek:

What do you tumble with it?

I wasn't too far off was I? You need to put some more safety stuff on that, for real. Tie or pin it down. THAT THING IS HUGE!

Put up some video of that thing tumbling something.

We are a small aerospace machine shop. The reason for the monster is not just to 'deburr' but mostly to get a consistent surface finish, for anidizing and painting (saving man hours). And our parts are at least 8 foot long.

90% of the material we use is 7075 or harder aluminum. And the media we use is a mediem soft cone. 75% 1 inch. 25% 3/8 for small radios, and joggles. Dont think the media would stand up to long to steal or cast, but it is possible.

The machine is 10' long 24" wide 36" tall. It looks like a box but is rounded on the inside. A 1750rpm 3hp 60hrz motor, 2 3/16 inch shaft with about 35lbs of counter weights, All can be adjusted. 6 car springs, and most of the materials were taken of a old warner swasy lathe we junked out. Total cost (minus my labor) $4,000 most of that is media, 3,000 lbs.

Dont know if it will let me post video but will try,

A safety fence around it would be a good idea.

Also make a point of checking all your welds for fatigue cracking on a regular basis.

It's getting its own room. Building a addition so it can be anchored, and to cut down on noise in the shop.

As far as welds.... I was stuck with a stick welder. Dose that effect the integrity? There is penitration, but was not able to keep a weld longer that 8-10 inchs.

Nothing wrong with stick welding, it is just that any madly vibrating structure is likely to suffer from fatigue cracks and the ends of welds are good places for them to start.
