The new indexable turning inserts from Walter are designed for applications where a soft cut and high precision is required. This is achieved thru the FP2 geometry, which is a high positive (18°) rake angle geometry with soft hone that insures reduced cutting forces and vibration tendency. High tool life is achieved thru WEP10C coated cermet grade with multilayer TiCN TiAlN PVD coating and fine cermet micro grain. The combination of edge preparation and grade also ensures dimensional stability over long periods of time, which boosts productivity in mass production
The new FP2 geometry also uses “minus tolerance” or “maximum corner radius” tolerance. This allows for a stronger corner radius to be presented than a standard ISO/ANSI corner radius. For example, to machine a shoulder with 0.0157″ corner radius, usually ANSI-0.5 corner radius (0.0078″) is required. However, with the FP2 geometry, a 1M tolerance (equivalent of ANSI 0.0157″ but 0.0146″+/-0.0008″ tolerance corner radius) can be used. The advantage is that a much stronger corner radius boosts tool life and also surface finish to machine the same feature. These new inserts are well suited for finishing thin-walled components, components with small diameters, long components, and components with unstable clamping as well as fine boring applications.
