ISOTURN INSERTS 148 SNMG-EM-M Double-Sided Square Inserts for Medium Machining on High Temperature Alloys Dimensions Tough Hard Recommended Machining Data Designation di S r IC806 0 8 IC IC907 ap (mm) f (mm/rev) SNMG 120408-EM-M 12.70 4.76 0.80 1 i 1.00-3.00 0.20-0.40 Requires the use of RST 443R/L SET - seat when used on DSSNR/L tools and TSN 423-PIN SET seat when used on PSSNR/L-JHP and PSDNN-JHP tools For user guide and cutting speed recommendations, see pages 197-212 For tools, see pages: DSDNN (36) DSSNR/L (37) Correct insert position Wrong positioning Orientation pin 0.45 f (mm/rev) Material: Inconel 718 Vc: 50 m/min With coolant The inserts have 4 cutting edges (2 on each side) with truncated radii - a configuration which facilitates heat transfer from the cutting area. The two edges without chipbreakers (flat) are not used. Toolholders These inserts require the use of RST 443R/L SET - special seat when used on DSSNR/L tools and TSN 423-PIN SET seat when used on PSSNR/L-JHP and PSDNN-JHP tools. The standard seats should be replaced with the special ones which have a pin whose purpose is to prevent using the nonworking flat cutting corners. Advantages Increased cutting speed (due to better heat transfer) Reduced notch wear (due to 45° approach angle) Increased feed (the 45° approach angle produces a thin chip) Increased productivity of up to 50% Ability to machine in two directions with the same tool, longitudinal and face turning Up to 3 mm depth of cut Chipbreaking Range SNMG 120408-EM-M ap(mm) ISCAR
