Precision Deburring Tools

Our high quality standards do not only apply to our deburring machines, but to our deburring tools as well. We place great emphasis on the material quality, precision manufacturing and enhanced lifetimes of spare and wear parts. Most often, successful processing depends on the small things. So we offer you only tools that will be able to complete the job correctly, the first time. In our ARKU online store, you can find suitable tools and wear parts for your deburring machine.

What is the right deburring block for me?

The choice of a suitable deburring block for your application depends on various factors. First of all, the appropriate machine-tool combination that will deliver the best results depends on your edge requirements. Besides deburring and rounding, the decision criteria could also include the material mix or the desired surface finish. Depending on these criteria, we can help you select the best and most economical tool. We can also verify this result by running tests parts.

What is a deburring block made of?

A deburring block consists of a base that is tightly packed with high quality grit attached to an abrasive fabric side by side. The base is configured with a patented quick-change system which allows the block to be changed in just a few seconds. The abrasive fabric is arranged at an angle so that the tool can use its high pressure impact at the sheet metal edge. Deburring blocks are available in various grits.

What is an edge rounding block made up of?

An edge rounding block consists of a base where high quality grit is attached to abrasive fabrics and non-woven abrasives which are arranged in an alternating fashion. The base is configured with a patented quick-change system which allows the block to be changed in just a few seconds. The abrasives are flexible so that they create a preferably strong radius on the edge while moving across the sheet metal. Rounding blocks are available in various designs with different grits.

Rotary & Roller Brushes

ARKU rotary & roller brushes ensure the best possible and uniform rounding of sheet metal edges. The brushes rotate across several axes and can thus strike all the sheet metal edges multiple times. A radius of up to 2.0 mm is possible for some applications. The tools come in various designs so you can influence the degree of rounding on your parts, as well as the surface or the processing speed. Depending on your processing requirements, we will select the suitable roller brush together with you.

Roller brushes for oxide removal

A special purpose tool for the removal of oxide byproducts from your cutting edges.

Do you have different designs for edge rounding rollers available?

Yes. The decision on how your tool should be chosen depends on certain factors. First of all, your range of parts and the requirements on your sheet metal edges determine which machine-tool combination can best meet your requirements. Besides rounding, the decision criteria could also include the material mix or the desired surface finish. Depending on these criteria, we can help you select the best and most economical tool for your application. We can also verify the selection by running test parts.

How is a roller brush built?

All around the central hub of the tool, you will find abrasive lamellas which consist of an abrasive fabric and abrasive grit. The tool’s characteristics are defined by the design of the abrasive fabric. For example, fine particle sizes remove less from the sheet metal, while coarser particles will remove more material. Accordingly, rounding of the edge will be greater. ARKU roller brushes come with a quick-change system. Thus the tool is changed in just a few seconds.

What do I have to consider when choosing a roller brush?

First of all, it is important that you are clear about the desired result. Including for example, the edge rounding result, the surface requirements, the processing speed or the parts or material mix. Another consideration is what materials you process. You should not process steel and stainless steel with the same tools to avoid steel particles being carried over onto the stainless steel surfaces. Also, parameters such as grit type or grit size of the installed abrasive filament are important tool characteristics that will define the processing result. ARKU customers will receive the corresponding product information along with the tools and expert advice that enable them to choose suitable products. You should also make sure that verified OEM spare parts are used in order to achieve the best result and avoid damage to the machine.

Discs to remove slag

Slag hammer to remove slag.

Discs to deburr and edge round

Non-directional deburring and edge rounding of sheet metal edges.

Discs to remove oxide

Specifically designed for the removal of oxide along the cutting edges.

What disc brush designs are available?

Tools can be divided into one-row and two-row brushes. The two-row arrangement ensures a more uniform finish. Different types of filaments impact grinding performance and thus the edge rounding radius or the processing speed of the deburring machine. The optimal tool for any application can be provided by varying the filaments or grit sizes.

What is the disc brush used for?

Disc brushes are particularly suitable for edge rounding. They are also capable of removing small burrs or secondary burrs. Yet the actual job of disc brushes is the edge rounding of sheet metal edges. However, with the appropriate tool-machine combination in the EdgeRacer®, they also succeed in removing oxide along the cutting edges.

Specific disc tools are built to remove slag. The disc used for slag removal is equipped with carbide pins that will chip off the slag from the plasma and oxyfuel-cut part.

Abrasive Belts & Non-woven Abrasives

Abrasive belts remove the burr from the part’s edge. This is usually the first step performed by the deburring machine. At the very end is surface finishing of the sheet metal, if desired. The associated non-woven abrasives deliver the necessary texture to the sheet metal. ARKU abrasive belts and non-woven abrasives are available in different designs. Ask us about the options that improve your deburring process by the choice of the ideal abrasive belts and non-woven abrasives.

Non-woven abrasives

What different abrasive belts are available?

Once you have selected the appropriate dimensions, then grit type and size will define the different characteristics of the abrasive belt. For example, a coarser particle size delivers a higher grinding performance than fine grit. However, the type of grit also affects the “durability” of the abrasive belt. That is, the degree of the abrasive belt’s wear. Zirconia corundumfor example, is self-sharpening and thus has a longer life than an abrasive belt made of alumina.

Which kind of non-woven abrasive for which application?

The surface finishing possibilities of a deburring machine are limited. The units in deburring machines are not suitable for a targeted normalized finish that we know from steel service centers. Nevertheless, the sheet metal surface can be improved by an additional wide belt unit and its non-woven abrasives after deburring and edge rounding. Basically, the choice lies between two different non-woven fabrics. The choice of “grit” sets the roughness or texture of the surface. Hence, in common applications that are used in sheet metal processing, they are able to achieve the desired surfaces for further processing.
