Abstract (English):
A well-known technology of machining weld surfaces in case parts of freight cars is analyzed. Its drawbacks are defined and eliminated by means of the development of techniques based on the use of high-capacity combined cutters. Combined cutters ensure a high-capacity machining of weld surfaces during one travel and zero back angles increase expensive hard-alloy plate life by a factor of two. Cutters are tested in the course of mentioned surface machining which confirmed their high efficiency.

Keywords:
machining, case part, weld surface, combined cutter, productivity.
