SUMIDIA Flank Wear (mm) SUMIDIA N Non-ferrous Metal DA1000 - General Features SumiDia DA1000 is a high density, ultra fine grained sintered PCD with high toughness similar to that of cemented carbides. SumiDia DA1000, with its great improvement in fracture resistance, eliminates the breakage problems faced by conventional PCD tools especially during the milling of Aluminium alloys and achieves a longer and more stable tool life. Furthermore, the NF type inserts makes it even more cost effective. - Cutting Performance DA1000 Conventional PCD Wear Resistance in Turning Application DA1000 0,20 0,16 Conventional PCD 0,12 0,08 0,04 DA1000 0 2 4 6 Cutting Distance (km) Work Material: 17% Al-Si alloy Work Material: 17% Si-Al alloy Insert: TPGW 160308 Insert: TPGN 160304 Cutting conditions: vc= 1.000m/min, f=0,15mm/rev, ap= 0,2mm, Wet Cutting Conditions: vc=800m/min, f=0,12mm/rev, ap=0,5mm, Wet NF Type Inserts - General Features Total Cost Effectiveness with High Performance and Lower Price • Long, stable tool life and good fracture resistance with high toughness grade DA2200. • Optimum design utilizing improved mass production techniques provides a relatively lower cost. • Regrindable type results in huge total cost reduction. Wide Application Range • Wide range of stocked items for small hole boring, OD turning to milling processes. • Negative and positive type inserts that are applicable on standard lever-lock, pin-lock type holders. - Efficiency l NF-Type Edge SumiDia NF-type inserts preserve the excellent basic performance of DA1000 while achieving high cost performance through optimal design and development of mass production technology. These inserts achieve the high performance of SUMIDIA DA1000, including excellent fracture resistance, wear resistance and smooth work material surface finishing. (NF-type is precision ground just like - Application Examples conventional inserts.) Milling of Aluminum Oil Pump Cover Boring of Aluminum Valve Bore Results:1,5 times longer tool life thancompetitor‘s with higher costeffectiveness. Results:No initial chipping, tool life is morethan 50 times that of carbides.
