TC system – thread turning
C35

System TC for thread turning is an integrated part of the MSS
system. Compared to traditional systems TC offers a series
of advantages which are of decisive importance for many
threading applications.

System TC Conventional system

○ Neutral configuration of insert makes operation in both ○ Right-hand and left-hand version of insert, therefore
directions possible operation only in one direction
○ Only one threading insert per pitch for partial profile and ○ For every pitch 4 threading inserts are necessary (right-
Whitworth thread; only two threading inserts (internal - and left-hand, internal - external)
external) per pitch for ISO threads
○ Reduced storage
○ Good chip formation through chip groove with rake angle
+10°

Overhang
Overhang ○ for this machining method 2 tools are necessary

Parting and grooving / Introduction ○ fewer tool changes overhangs
Enhanced economic efficiency through
○ additional loss of stability and material caused by large
○ reduced machining time
○ improved stability, small overhang
○ material saving
○ thread turning between shoulders possible
○ fewer tools and inserts
