Zefektivnění výroby obrábění hřídelí elektrických generátorů v podmínkách OSTROJ a.s.

Abstract

Master thesis deals with effectivity in machining of shafts of electric generators. The thesis focuses on the technology of turning, dribbling, milling and cutting of the thread. The introduction compares the current technology of machining of the shaft. Based on a comparison of each technology, the new technological process for the shaft production is suggested using progressive tools. The new manufacturing process unites the operation II. –“Alignment and drilling” and IV. – “Turning” into one operation. This operation is performed on CNC horizontal center MCFHD 80 PVS using progressive tools. In the operation III. –“Turning” on CNC machine the author replaces the existing blade discs and inserts more progressive. The operation V. – “CNC milling grooves” the author suggests a change of strategy with the use of slot machines on the D17.7 mill.
