Dapra Opens Midwest Tech Center in Illinois

Walter USA has introduced the Walter Cut G1111-P/GX24 AF5 axial grooving system, featuring the G1111-P GX monoblock tool for axial grooving slot milling cutters and groove turning with precision cooling. It is said to provide reliability and longer insert life due to its reinforced cutting edge (for example, 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 a diameter of 2.362" (60 mm), cutting depths up to 1.299" (33 mm), with insert width of 0.197" (5 mm). The new system reportedly 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. Walter says axial grooving is effective when the groove depth is 1.5X greater than the groove width, but to be successful, axial grooving requires dedicated tooling and a dedicated chip control insert.

Key to APKT Insert the system’s success is also 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 enables 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" (60-500 mm).
