Seco has launched the new R220.88 face milling cutter range with inserts with eight cutting edges and improved geometries. The cutter body’s 88-degree lead angle allows for large depths of cut with smaller insert sizes than 45-degree lead angle face mills. Its design also allows the new cutter to machine closer to workpiece side walls as well as intricate part clamping workholding systems, the company says.
Designed for roughing and semi-finishing applications, the R220.88 is suitable for machining cast iron and steels in the general machining and automotive segments. The cutter body is made of Idun material, a corrosion resistant stainless steel that offers longevity and durability along with being environmentally friendly due to the elimination of the nickel coating process.
The cutter body is available in diameters ranging from 50 mm to 160 mm on the size 12 insert and 63 mm to 160 mm on the size 16 insert. The Size 12 R220.88 achieves a maximum depth of cut of 9 mm, while Size 16 reaches an 13 mm maximum depth of cut. Right-hand versions of the cutter body are standard with left-hand versions available on special order, allowing integration into systems with dual spindles performing simultaneous milling operations.
The R220.88 is compatible with Seco’s SNMU inserts, which are secured with a center lock or screws, eliminating the need for wedges to secure the insert in the pocket. The eight cutting edges on these inserts offer double the cutting edges over four-edged inserts to help reduce tooling costs.
