Also, for internal turning operations, the same series features an extension of the -A chip breaker geometry.
In direct response to demand from manufacturers of pump components, face grooving depths of cut of up to 30 mm are now achievable using the CoroTurn XS family. The previous maximum was 6 mm. Suitable for all engineering materials, the new size 08 insert is for 3-15 mm depths (2-4 mm widths) on diameters 10-16 mm, while the new size 10 insert is for 5-30 mm depths (3-5 mm widths) on diameters 12–20 mm.
Complementing the inserts are new adaptors/holders for boring bars, Coromant Capto toolholders and shank-type holders, ensuring the new tools can be used on all kinds of lathes in internal and external tool positions. Internal coolant is facilitated through the holder, while a locating pin allows easy and exact location of the insert to reduce indexing time.
For general internal turning operations using the same family of tools, the extension of -A geometry inserts in sizes 04, 05, 06 and 07 delivers better chip control, enhanced process security and longer tool life.
