Walter has introduced the Walter Cut G1111-P/GX24 AF5 axial grooving system, featuring the G1111-P GX monoblock tool for axial grooving and groove-turning with precision cooling.
The system extends insert life due to its reinforced cutting edge (e.g., with forged parts), and incorporates precision cooling on the rake face with a coolant jet aimed at the clearance face for flushing the chips out of the axial groove.
The system handles axial grooves from dia. 2.362 in. (60 mm), cutting depths up to 1.299 in. (33 mm), with insert width of 0.197 in. (5 mm). Walter says that it delivers maximum productivity and cutting parameters due to optimal cooling, strength and controlled chip breaking, along with high cost efficiency due to two cutting edges. Axial grooving is effective when the groove depth is 1.5 times greater than the groove width, but to be successful axial grooving requires dedicated tooling and a dedicated chip control insert.
A big part of the new release is the new Walter Cut GX24 grooving insert with AF5 Axial chip breaker. This new right or left-handed asymmetric chip breaker takes into account the variation in cutting speed on the outside and the inside corner of the insert. The new AF5 chip breaker geometry has uneven chip breaker grooves, with shallower groove on the outside cutting corner and deeper groove towards inside cutting corner. This allows for a very efficient chip breaking operation and a smooth, scratch-free finished workpiece surface.
The Walter Cut G1111-P grooving holder has a diameter range of 2.362-19.685 in. (60–500 mm).
