11'iunLTEn Valenite Walter Select for indexable inserts for precision boring Step by step to the right indexable insert STEP 1 Determine the material to be machined, see page H 8 onwards. Note the machining group that corresponds to your material e.g. P10. Identi- fication letters Machining group Groups of the materials to be machined P P1-P15 Steel All types of steel and cast steel, with the exception of steel with an austenitic structure M M1-M3 Stainless steel Stainless austenitic steel and austenitic-ferritic steel and cast steel K K1-K7 Cast iron Grey cast iron, cast iron with spheroidal graphite, malleable cast iron, cast iron with vermicular graphite N N1-N10 NF metals Aluminum and other non-ferrous metals, non-ferrous materials S S1-S10 High temperature alloys and titanium alloys Heat resisting special alloys based on iron, nickel and cobalt, titanium and titanium alloys H H1-H4 Hard materials Hardened steel, hardened cast iron materials, chilled cast iron O O1-O6 Other Plastics, fiber glass and carbon fiber reinforced plastics, graphite STEP 2 Select the machining conditions Type of cutting action Machining conditions Smooth cut, level entry or exit surfaces a Laminate bores Cast and forged inclines < 5° Bores with interrupted cuts Cast and forged inclines > 5° c STEP 3 Determine the indexable insert geometry via the material and the projection length.
