Addressing the challenges of machining titanium parts for aircraft, Sandvik Coromant has introduced the CoroMill Plura HFS solid-carbide end mill. It exploits milling strategies such as high-feed side milling (characterised by low radial engagement, constant chip thickness, and high feed rate and speed). Sharp edges combine with a new coating that features a TiAlN inner layer and a silicon-containing outer layer. The outer layer reacts with titanium alloys and forms a sub-micron protective layer. During cutting, chips glide on top of the protective layer, preventing fast deterioration of the original coating and prolonging tool life.
Tangentially mounted inserts
Turning inserts and toolholders combine to provide users with four useable cutting edges. In addition to maximising the number of cutting edges, by tangentially mounting the inserts, a stable process is ensured, even under extreme cutting conditions. This is further enhanced by the availability of a coolant supply that can be precisely directed and fed from either the rear or side of the toolholder.
Horn Cutting Tools offers Boehlerit’s new turning toolholders with connections for internal coolant supply. They are available from stock with toggle clamp (ISO-P) and screw clamp (ISO-S) systems, allowing manufacturers to benefit from the productivity advantages of cooling directly at the cutting edge.
Wave mill expanded
Sumitomo Electric Hardmetal has extended its WFX-Type Wave Mill screw-locking shoulder milling cutter range using the proven economic advantageous series of four corner inserts into, a high feed rate multi-purpose roughing, and WFXC chamfering-type bodies. By maintaining the use of existing inserts in the WFX Series, tool management and stock holding of inserts becomes more economic, extending their use to a wider range of applications.
