Explosion Deburring/Extrude Hone Deburring

[Zoffen]

Doe anyone have a good source to get one of these processes done to some aluminum hydraulic manifolds? In this case the customer would possibly be looking to buy a unit eventually after proving the process for their parts. Thanks for any info!

I have never heard of explosion deburring.  Gonna have to Google that.

Extrude Hone used over a decade ago and it does good work. On the explosion deburring I cannot comment on.

Simple search found this:

I think the explosion process is this method:

This is where we send our parts for thermal deburring (explosion)

It is very violent though, if the walls are thick and there can be some handling damage it's fine. But we tried it on some very thin medical parts and while it does work we did lose some parts in the process.

Another option to consider is cryogenic deburring.  Essentially media blasting with dry ice media.  Works great on plastics and rubbers from what I hear; don't know about metals.

Awesome! The parts the customer has look exactly like the ones on the homepage lol. Thanks for the info.

I will look into the cryogenic deburring also.

Thanks for all the info!

We have two thermal "Explosive" deburing machines here. All I will say for the process is that it needs to be a very fine bur for thermal to remove it. Also, beware of any loose "hangers" get welded on during the process. Or, larger burs getting blown off and bouncing around in your manifold.

This is a place here in Michigan, though there website is pretty lackluster, they do thermal deburring.

We use both processes, the explosion deburring process is outsourced but we do have one abrasive flow machine here at the factory. AFM not only deburrs, you get excellent surface finish with it, though the process is very slow and thus should only be used when superior surface finish of internal holes and cavities is required. Lead time depends on medium and its temperature, cylinder pressure and especially fixture design - be prepared to spend some time on designing them. With a two-way machine you can drive the medium from lower to upper cylinder and back without having to put the medium back in the machine every time. It is dirty work.

You may want to look into electro-chemical deburring also.  Special electrodes would have to be made for the different part numbers, but very controllable.   Chemtool was the company that did it as well as selling equipment but they don't seem to be around anymore.
