It is used to remove internal surface imperfections and to deburr the inner diameter of the tubes.
The tube rotates by means of driven radial steadies and a guide arm with a grinding disc is inserted into the tube. The disc consists of a set of grinding stones.
Material removal - up to 0.5 mm / hour by the tube length up to 6,000 mm.
Tubes longer than 6,000 mm must be ground from the other side with a second parallel grinder or by turning the entire tube.
The grinding runs dry with suction and filtration of the exhausted air.
The grinding can be done manually or automatically via the control panel.
