Twelve independently controlled grinding modules use frequency-controlled electric motors. The operator selects and monitors the computer-controlled grinding process from the cab through a touch interface.<\/p>\n<p>Published applications include removing mill scale and rolling skin, treating corrugation and short waves, restoring transverse and longitudinal rail profiles, and grinding turnouts. The machine can grind in either direction and stores up to 100 grinding programs.<\/p>\n<p class=\"rgw-note\">The supplied technical sheet records R40 m as the minimum travelling radius and R50 m as the minimum grinding radius. The current L&amp;S series page gives 60 m for RGM 1-12 without separating travel and grinding conditions. Confirm the delivered configuration with the machine documentation.<\/p>\n<\/section>\n<section id=\"comparison\" class=\"rgw-section\"><span class=\"rgw-kicker\">Series context<\/span><\/p>\n<h2>RGM 1-12 vs. RGM 1-10 and RGM 2-16<\/h2>\n<p>The RGM 1-12 sits between the 10-module RGM 1-10 and the two-unit, 16-module RGM 2-16.
