Návrh nové technologie opracování odlitků z manganových ocelí ve firmě Slévárny Třinec, a.s.

Abstract

In my diploma work I'm dealing with machining of Manganese Steel castings. I examined manganese steal according too its structure mentioned its ability of hardering dutiny machining (turning, milling), Wnich require special's methods during machinig operations. Generally described obout milling and turning. I focused on the using of the most conveinent cutting tips for machine tools in the purpose to have machining opperations. I described the ways machining from SK whith several times plating, which were the most convenient, which machining specific products. In this case it were frogs for railweys and cones for crushers produced in Slevarny Trinec, a. s. Based on parameter tool tips made by PRAMET TOOLS s.r.o. from cubical nitrid borid with several times plating and nanostructural coat. I calculated the costs of milling and turning from used data during machinig. I compared these results whit former results whith used others cutting tips from CBN and SK and appoint economized whith new methods of machining.
