XFGT001 CNC Rail Web Weld Grinding Machine

A total of six grinding heads are installed on the left and right sides of the equipment. The CNC axes governing the feed direction of each grinding head are precisely controlled by servo motors, and the rail web weld is ground in the following sequence: first, a form-grinding wheel matching the contour of the rail web is used to grind weld section 1; next, a form-grinding wheel aligned with the bevel of the rail foot is employed to grind the bevel of weld section 2; finally, a form-grinding wheel conforming to the profile of the rail foot edge is used to grind the rail foot edge. The entire grinding process is conducted as dry grinding, with the machine tool equipped with a dust-proof enclosure and an impulse-type dust-collection system that effectively captures grinding dust, thereby meeting environmental protection requirements.

XF Series Centerless Grinder for Tapered Roller and Round Steel Bars
