PWSR Type, with a 2-stage insert array structure supporting large depths of cut, has been added to the lineup. H ■ Features ● Tangential inserts with excellent cutting edge strength and optimised breaker provide superb cutting edge and sharpness. ● Nicked insert design created with high-precision formation technology allows stable milling and low chatter even in applications with large tool overhang. ● ACP and ACK series allow a wide range of work materials to be covered. ■ Performance ● General-purpose G Type Insert Performance Comparison Comparison of Cutting Edge Strength Comparison of Cutting Force Strong cutting edge delivers superb stability Sharpness approaching that of screw-on inserts 1,000 3,000 1st Time Principal Force 2nd Time Feed Force 800 3rd Time 2,500 Back Force ○: No Breakage, Good Cutting Edge ×: Damaged, 2,000 600 Unusable 1,500 Cutting Conditions Cutting Conditions 400 vc=150m/min vc=150m/min fz =0.20mm/t 1,000 fz =0.20mm/t ae=3mm ae=3mm 200 ap=10mm ap=10mm Dry 500 Dry Work Material: S50C Work Material: S50C Tool Diameter: 80mm Tool Diameter: 80mm 0 0 SumiPower Mill Competitor's Product A Competitor's Product B SumiPower Mill Competitor's Product A Competitor's Product B PWS Type (Screw-on) (Vertical) PWS Type (Screw-on) (Vertical) ● Nicked R Type Insert Performance Comparison Comparison of Cutting Force Nicked R Type Insert General-purpose G Type Insert Reduced cutting power and excellent chatter resistance 7,000 R Type G Type 6,000 Reduced by 25%! 5,000 Small chips! 4,000 3,000 Cutting Conditions vc=200m/min 2,000 fz =0.15mm/t ae=20mm ap=10mm 1,000 Dry Work Material: S50C Tool Diameter: 100mm 0 Nicked R Type General-purpose G Type Nicked R Type Insert Usage Precautions 4 notches(Corners (1) and (4)) 1) Precautions when MountingWhen using the nicked R type indexable inserts, mount them so that the nicked grooves alternate as shown in the image on the left. (3) (4) 2) Precautions for Cutting ConditionsAs these are mounted as in the image on the left, compared to mounting inserts of the same shape for all blades, the feed rate per tooth is doubled. Accordingly, (4) 3 notches fz = 0.25mm/t (Corners (2) and (3)) feed rate is set as the upper limit and can be adjusted for use. Ex.) For use with fz = 0.2mm/t (3) (3) With all regular blades: Feed Rate per Tooth 0.2mm/t (4) With nicked types: Feed Rate per Tooth 0.4mm/t Using inserts incorrectly may damage tools. H137
