摘要： PURPOSE: To bring a grinding blade into contact freely with the top face, arcuate surface and side faces of a rail head section and grind a welding residual section, to load the load of a driving motor for grinding to a cutter body and to conduct grinding work more surely by vertically moving a first support disk or laterally moving a second support disk while forwarding or retreating a machine base as required. CONSTITUTION: A device substrate 24 is disposed in upright on the front end side of a machine base 1 capable of being forwarded or retreated along a rail R. A first support disk 25 vertically moved by operating a first driving motor 27 is installed to the device substrate 24, and a second support disk laterally moved by working a second driving motor 30 is assembled to the first support disk. A driving motor 35 for grinding and a cutter body 37 linked with the driving motor 35 are mounted on the front of the second support disk in a horizontal-shaft rotatable manner. An engaging section, with which the head section R' of the rail R is engaged, is fitted to the cutter body 37. Grinding blades grinding each of the top face, arcuate surface and side faces of the rail head section R' are set up to the engaging section.

摘要： PURPOSE:To smoothly grind a rail in a short time without steps in the ground rail, by equipping mutually engaging gears on a rotary shaft of two grinding bodies to grind each end of a rail. CONSTITUTION:Mutually engaging gears 4, 4 are equipped at the rotary shaft 5 of a grinder 1 to grind a half in the width direction of a track rail and at the rotary shaft 5 of a grinder 1' to grind the other half respectively. And cutting blades 3a-3f of which rotary tracks are mutually superposed between the grinders 1, 1' are provided at the grinders 1, 1'. Recessed lines 2... are made to correspond to the head R' of track rail R in the grinder 1, 1' and an appropriate number of cutting blades may be detachably fitted in the recessed line 2. And hence, the grinders 1, 1' rotate with the same number of revolutions because of the engagement of the gears 4 and the head of rail can be ground evenly on the right and left sides.
