Grinding of pipes with a diameter of 6 – 90 mm.<\/p>\n

The grinding machine is used to achieve high quality grinding surface of pipes and to remove surface defects after drawing and cold rolling. The pipe is inserted into an infeed roller conveyor which gives the pipe rotation and moves the pipe into the grinder.<\/p>\n

The grinder consists of 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. At the outlet of the grinder, the pipe exits into an outfeed roller conveyor. After traversing the entire length, the rotating tube stops and is tipped onto a tray table.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n
