From roughing through to fine finishing steel workpieces

Highly productive finishing is targeted by Tiger.tec Steel grade WPP01, which features particularly sharp cutting edges, while WPP05 is designed for roughing/medium machining. Both inserts offer top cutting speeds and stock removal rates, says Walter GB WPP05 with its associated cutting geometries is designed for components requiring near-net machining with allowances of just 1 to 4 mm. The inserts cleverly combine a mixture of aluminium oxide (Al²O³), titanium carbon nitride (TiCN) and titanium nitride (TiN) coatings on a tungsten carbide substrate, featuring a grey (TiCN) rake face and a golden, TiN finish (flank face) that aids wear identification. The aluminium oxide coating is particularly effective against tribochemical wear and permits higher cutting speeds and feeds to be employed while also providing longer service life. The golden TiN coating applied to the inserts' clearance surfaces simplifies wear detection and thus avoids the unnecessary waste of unused cutting edges. The grey TiCN rake face minimises negative tensile stress and improves adhesion and toughness
