Deburring and edge chamfering at Dumaco

An optimal cutting process will result in virtually no burrs. However, there may be some spatter and/or burrs eon the underside of the sheet metal. At Dumaco, we can debur, edge-chamfer and rotofinishing your sheet metal for you.


Deburring ensures that all your products are spatter and burr-free. After deburring, the edges of the sheet metal will still be sharp. Both manual and machine deburring are possible.

Edge chamfering

Dumaco can also chamfer the edges of sheet metal for you. This is an extra process, which machine-chamfers the sharp edges of sheet metal. We use our brushing machines for this purpose. They remove burrs, contamination and sharp edges as well. Sheet metal feels smooth afterwards. Single and double-sided edge chamfering are possible.

At Dumaco, we process (stainless) steel products on various machines to eliminate the risk of contamination. Our customers often opt to have the edges of steel products chamfered in combination with post-treatment. The post-treatment technique is used on stainless-steel products to avoid any chance of sharp edges cutting professionals who are working in a damp environment. This makes the product a lot safer for the employees of our customers.


We use tumbling to chamfer the edges of small stainless-steel parts. Dumaco has various tumbler machines.
