30 GSN-100 Jethete M152 Milling

31 A 82% iron, 12% chromium material classified as a Martensitic Stainless Steel which has high tensile strength and sufficient ductility at elevated temperatures as well as high corrosion resistance. The material is very sensitive to heat during the machining process which makes the material rapidly work harden. The application of Jethete M152 is mainly in high stress gas turbine parts. Jethete M152

32 Jethete M R/C Cutter: WSRP RH Insert: RPGN-43 T1A HSN-200 Speed: 1500 SFM (458 M/Min) Feed:.0033 IPT (.08 MM/tooth) DOC:.050 (1.27 MM) WOC: 2 (51 MM)

33 3 ½-4 minutes cut time, inserts showing flank wear, and experiencing heat in part Jethete M R/C Cutter: WSRP RH Insert: RPGN-43 T1A HSN-200 Speed: 1600 SFM (488 M/Min) Feed:.0015 IPT (.04 MM/tooth) DOC:.050 (1.27 MM) WOC: 1.25 (31.8 MM)

34 4 minutes tool life, 37 % increase in feed over HSN-200s best run! Jethete M R/C Cutter: WSRP RH Insert: RPGN-43 T1A GSN-100 Speed: 1600 SFM (488 M/Min) Feed:.0028 IPT (.07 MM/tooth) DOC:.050 (1.27 MM) WOC: 1.5 (38.1 MM)

40 Review Silicon Nitrides have their place in the high speed ceramic machining market. Grades such as Greenleaf GSN-100 work well in interrupted cutting and Milling operations due to Silicon Nitrides high thermal shock resistance. Greenleaf GSN-100 works well in the machining of Gray, Ductile, and Nodular cast irons. Although developed for Cast Iron machining, Greenleaf GSN- 100 works on other materials such as selected high temp alloys. You will want to start gearing your HSN customers to the new Greenleaf GSN-100. ® ® ® ®
