How to Avoid Chips All Over The Place While Using The Threading Process?

03/08/2017 12:01 PM

Hi, At my plant, there's a threading machine and the place has become an absolute mess because of all the chips that fall over the place.

I need Ideas to control this problem, I know that eradicating the chips is impossible because of the nature of the process but at least prevent it from falling everywhere.

At the moment this is the system.

As you can see there are chips everywhere and the black box covering the threading machine works as a security guard or cage to prevent the chips falling all over the place but still It's not very effective.

I need suggestions.

Hahaha obviously we clean it but I'm talking here of a constant operation with Big tonnage tubes rolling around, entering the area to clean while operating it's not accepted.

Maybe a big vacuum cleaner....? ...or possibly a robot with compressed air blowing the scrap away with a grated floor that the debri drops through to a concrete surface swept with a street sweeper...

That's actually a nice idea but It'll be difficult to install it on the top of the conveyor

Don't know how much chips that machine would produce... but I've worked on machines that would produce over (1) 55 gallon barrels of uncontained chips in a 10 hour shift.

And that was with a vacuum system taking away the majority of chips.

It depends on what kind of metal you are threading. If it is iron, you might be able to collect it with a magnet behind a plastic or paper barrier. (From the looks of the turnings, to me it appears to be aluminum. )

It's steel, and actually we use that technic but it's not very effective, I'm planning on implementing something in conjunction with that system.

I'm thinking on installing some kind of flexible material to emulate a door in the entrance of the threading machine, in order to clean the chips that are fix in the tube, but I'm not sure about the material of it.

Rather than a door you could use a radial strip brush slightly smaller than the tube so that it keeps the swarf inside your shield & sweeps the tube clean as you withdraw it.

For machine tools, we made up a housing and mounted these brushes below it.

Being aluminum mount, you can form it to the housing.

Look at the link and see if something fits your process.

You have two choices, either eliminate the chips or contain them.

To eliminate them, would thread rolling be an alternative? Can the chips be made smaller and easier to manage with changes in cutter inserts, speeds, feed rate, feed action, etc.?

To contain them, you could have knowledgeable fabricators custom-build a containment guards to encapsulate the area with appropriate access doors and interlocks to not impede tool changes, part loading, etc. Perhaps integrate air knives or magnetic chip evacuation to direct the chips out of the machine. A detailed 5S plan for this process would be advisable to round out the plan.

Uncontrolled chips flying about is a SERIOUS safety risk that your company should make a priority to mitigate.

Yes, as I wrote on the description we have a guard system that prevent that flying chip and works just fine, the problem is with the long chips that are left fixed on the surface of the tube so when it starts rolling in the differents conveyors those long ships fall everywhere in the area.

I would think long ships would be an even more serious problem than long boats with Vikings in them. This thread has been answered. Use an internal brush, and if you need, an external brush on the area where the tubes roll away from the thread cutter. Air curtain could be an option, however, I dislike the idea of air jets anywhere near cutting operations since it could pose a safety risk you should not take with respect to swarf in the eyes.

I have large and strong rare earth magnets taped inside the bristles of my shop broom and it's amazing how much of a difference it's made. I also have strong magnets behind plastic near metal shooting tools. When I pull the magnets the chip and grinding bits fall into my 'save ferrous' bin.

Mainly I go to the effort so when my dog wanders in on me I don't have to worry about his feets.

That is odd. You dog has feets, and also all four of my dogs have 4 feets. I used to have a snake-bit dog with only three legs, but he still had feets. How about that.

There were reports of a fellow near my city that worked in the oil patch that used to just hang the spigot out the side of his coveralls (to the disturbance of all around) when nature called.

No, no. The dog (a chow named Butch), got bit by the snake whilst Butch was attempting to drown it in the stock tank (the way he did rabbits after shaking them violently several times). My sisters wrapped Butch's leg in burlap sackcloth, and laid him in the barn (perhaps to die). He decided he liked living, chewed off his own leg, and came tripod walking up to the front porch of the house. My dad surely loved that old dog. When he had to be put down many years later, I saw my father cry for the only time I can remember.

BTW - north of Amarillo on the farm-to-market road that runs just south of Harrington Generating Station, I ran over a lane stretcher rattlesnake (over 8' length) while on my rice burner motorcycle. I thought that thing was going to climb on for a ride.

Instead, he just kept motoring across the road like nothing happened. I had locked wheels trying to stop to see where he was.

Just a minor point, but if you are 5S'ing it, you should re-paint the guard yellow. I know it will be done eventually, but if you are doing a report others read it will look good. Some factories like safety stickers on access doors too.

I have pondered on the idea of rigging flexible pneumatic nozzles to blast shavings airborne while a drop down shield funnels the pieces to a powerful filtered ducting drawn opposite from the user. To do this effectively may require some intricate sheet metal work and inserting a large diameter fan where a wall stands in order to make room.

Have you looked at the geometry of the cutting inserts. Chip breakers should be available for the machine. If not some one can machine them. Which would reduce the long strings. The brushes pictured in the other would help in containing the loose chips. I don't know how effective they would be in removing something thats attached. May want to look at something with stiffer bristles.

How to avoid >CHiPS< all over the place while using the threading process?

It's a simple process, slow down and don't thread your way through Rush Hour Traffic. And if you do see , stop- when it is safe, shut down the power plant, hold your hands up high and don't make any sudden moves! Your Busted and wishing you were back at the plant complaining only about the swarf.

I don't think you can brush that one aside
