Cold drawn and cold rolled tubes require the outer surface to be ground down to remove surface defects and to achieve a high surface quality. The pipe is inserted into an infeed conveyor with driven radial rollers, which imparts rotation to the pipe and moves the pipe into the grinding machine. The tube passes along a series of up to 14 grinding stations equipped with grinding belts. Each grinding station is equipped with its own pressure which can be adjusted by the operator. Grinding can be carried out wet or dry.

 Wet grinding grinds the material with a constant supply of coolant. The ground material is rinsed into the tub and conveyed out of the tub by a worm shaft. The water with the abraded material is filtered in three stages. Magnetic filter, fabric filter and mechanical separator. The solid residues are deposited in an attached pallet and the filtered water is reused for grinding.

In dry conditions, the grinding stations are equipped with a suction with filter station. Furthermore, the grinding stations are located in a dust-tight cabin.

Na výstupu z brusky trubka vyjíždí do výstupního dopravníku s radiálními válečky. Následuje vyklopení trubky na následné technologie.
