Deburring tools.

The grinding drum is the strongest deburring tool. That is why the grinding drum is used in particular for thick sheet metal and stubborn burrs. A drum covered with an abrasive belt pushes down on the metal edges. While the drum rotates, it grinds down the metal burrs from the parts. A large diameter and a flexible pad under the actual (circular) tool, the abrasive belt, ensures high pressure on the sheet metal edges and an excellent removal performance. For plasma and oxyfuel cut parts, the grinding drum is the established leader for deburring operations.

There is a large variety of different abrasives that can be used with the grinding drum. The type of grit, the grit size and hardness grade of the abrasives all have  an impact on the removal performance or the life of the abrasives themselves. Due to the large diameter of the grinding drum, particularly aggressive abrasives can be used, which underlines their uniqueness in the area of ​​heavy plate processing.

The advantage of deburring blocks is the ability to deburr sheet metal from the top and the bottom in a single pass. This is always useful if the parts cannot be flipped over (or should not). With stubborn burrs and/or splatters stuck on both sides of the sheet metal, both sides have to be processed. Double-sided processing in a single pass saves significant time and processing costs. The slightly higher costs of the tool (compared to the wide belt) are thus offset.

Deburring blocks are suitable for the removal of burrs created in laser cutting and punching operations. Since the sheet metal is held secure before and after processing, the process is also more tolerant should parts have warped slightly.  For larger burrs from plasma and oxyfuel-cut parts, the grinding drum is a better option than deburring blocks.

ARKU deburring blocks are available in high-quality Zircon corundum and ceramics design with various proven grit sizes.
