Tools to remove slag.

Slag usually forms on thick plasma and oxyfuel-cut parts. There are two reasons why grinding off slag does not make sense. First, slag cannot be completely removed, because only up to a certain level can be grinded down and the rest is pressed down. Second, there is an enormous amount of abrasive is used due to the slow grinding process which results in high abrasive costs.

The preferred method for slag removal is to literally chip it off the part with carbide pins. The slag hammer hits the side of the slag at high speed and breaks it off the edge. This robust procedure uses discs equipped with carbide pins that rotate and oscillate across the part. The part is held by rollers that move the part over the tools.

Various tool designs are available.
