うにして削正する研削手段が実用化しつつある。[0003] However, the manual grinder is complicated and lacks in workability because it removes the remaining portion of the welded portion by polishing, so to speak. For this reason, a grinding blade made of a so-called carbide tip is replaceably fastened to a grinding body (cutter) and the grinding body is rotated, so that the grinding blade is used to scrape off the remainder of the remaining welded metal. Grinding means is being put to practical use.

であった。[0005] When the old rail and the new rail are welded to each other, the old rail has a lower height and width than the new rail due to long-term use.
A step occurs between the old rail and the new rail (the old and new rails are welded so that the upper surfaces coincide with each other), and this step does not produce a favorable result in the inspection of welding and grinding accuracy (performed by a flaw detector). In some cases, simple removal of the step at the time of grinding the lower surface has been a problem in rail connection work.
