Indexable Tools Tooling by DIJET Finish Jet Mill FJMTYPE ■ CHIP SHAPE COMPARISON Work material: S15C, Tool dia.: ϕ200mm, Vc=300m/min, f=4mm/rev, ae=137mm DIJET Competitor B Chips by finishing insert Chips by semi-finishing insert ap=0.05mm ap=0.1mm ap=0.2mm ● FJM obtains excellent surface roughness and longer tool life by stable cutting due to adopting the combination of 2 semi-finishing inserts and 2 finishing inserts. This combination divides the chips and cutting force. Competitor B got chipping problem by excessive cutting force due to increasing ap. ● There is no step on the surface which is machined by FJM.
