DeBurring

[MatthewGoacher]

Hi all,

First post here so forgive me if i'm in the wrong forum etc.

I'm looking to source a hand held powered deburring tool, we obviously have the manual versions of these tools but the larger and more complex the work gets the longer this process is!

We are losing hours and hours deburring plates which is crazy!!!!

We have 'rumblers' for the smaller components but the large plates are obvioulsy not going in there.

Is anyone aware of either a pneumatic or electric version of the handheld deburring tools everyone uses?

Any other ideas would also be appreciated.

Thanks,

Matthew.

You haven't posted much information about you required end results on whether you need just deburring or some specific edge. Based on the limited information I would look at Flap Wheels as a starter.
Post back if more precision is needed.

these exist in both pneumatic and electrical versions, much sizes and widths. Very practical, however you must take flying dust into consideration: operators of CNC machinery shouldn't be using these near their machines.

Hi guys, thanks for the quick response's.

You certainly seem to be going down the right lines with this. We are CNC milling large (1.7m x 2m) and complex 20mm thick alluminium plates (ALPLAN), the holes are not an issue as they can be cleaned up as part of the programe and to be honest the edges are generally chamfered within the program also but we obviously have the reverse side to clean up, it's not an option to flip the plate on the machine because of time so we need something a bit better for the guys who are cleaning them up off the machine.

At the moment this is done manually with de burring tools (image attached) but we would like to make this faster, easier and safer!

I dont really want to go down the flap wheel route as this is a bit rough in truth and the plates need to retain a machined appearance. the manual de burring tools do at least provide a constant chamfer throughout, ideally we would be talking no less than 0.5mm x 0.5mm and no more than 1mm x 1mm.

I'm imagining something like a very small router?!?!?!?!?

Thanks again guys.

Scotchbrite - available in many forms and grades

Scotchbrite? Struggling to believe this is a serious suggestion for a manufacturing environment??!?!?!?

Here you go.

It is widely used in manufacturing operations. Not the scotchbrite found in your kitchen. Do a search, or call an industrial supply.

For the holes there are reverse chamfering tools:

For the outside edges you could mill a reverse chamfer on the bottom.

Here are two other options you might want to investigate, the Weiler abrasive nylon brushes.

From the CNC point of view I would look at the tools from EZ Burr as they just generate more chips and can be programmed by a tool change.

In my experience air powered deburring tools use about 2.5 times the rated amount of air per hour. Generally the rating is based on something vague such as "normal use".

Since you mentioned it, can you use a router? There are lots of different kinds of routers in the world.

I have seen ads for the kind of machine you describe but that's all I remember. Maybe search the magazines.

Might try posting on practicalmachinist dot com. Very good site for practical applications.

Good engineering starts with a Grainger Catalog.

There are a vast multitude of tools out there. You are now using one of the most basic hand tools. Look through the McMaster-Carr or Grainger catalogs (which are on-line). You have to have a clear idea of what kind of parts you will be working on and what kind of edge you desire. Look also at "chamfering" tools.

We regularly used off the shelf "wood" routers with carbide tooling for chamfering AL plates of all sizes, it is noisy with lots of chips flying but it works like a charm. Use small diameter tooling as they wear more slowly at the high rpms of the typical router.

Make sure you are climb milling the edges though, conventional milling tends to tear the AL leaving a rough look to the edge. A little squirt of kerosene helps with any chip welding you encounter.

Most routers have plastic bases screwed on that can be removed and custom bases made out of Nylon or other plastic to make it easier to handle on long cuts, we used a 90 degree edge made of Nylon for long plates to keep the tool aligned.

Also consider buying a good quality plunge router as it makes the operation safer, we actually rigged up a kill switch on ours so when the tool was plunged halfway the motor was on and off when removed from the work...like a deadman switch.

Good luck.
