Sumi Reamer SR Type ■ Characteristics ● Achieves efficiency through high speed, high feeding ability!! (vc= 50 to 500m/min, f = 0.4 to 1.2mm/rev) · Compatibility with a wide range of cutting conditions allows less strict cutting conditions and coolant control · Minimal cut edge length design eliminates biting and tearing for improved quality and reliability · Adoption of indexable cutting edge design improves reliability of quality and tool life, eliminating variability in tool life among reground inserts. · Cut edge diameters available from ø11.9 to ø140.6 mm ● Easy insert replacement ● Flexible tool overhang lengths possible by combining the modular extension arbor and shank with insert run-out adjustment mechanism Utosaeddjuifsfetrteonotl coovnefrihgaunragtiloennsgth A taper supports the insert by two faces (based on the HSK standard) for less-than 4 μm repeatability using random inserts ■ Application Examples J Work Drilling Special holder with guide pads Cylinder barrel Connection rod Sliding yoke Front axle Control valve Solid Work Material FCD600 Forged S55C S45C Forged S58C Forged S55C Special Holder SRD19-12-115 SRD36-25-170 SRD19-12-115 SRD29-20-240 Special holder with guide pads Insert SRG17.0H7-A01-T1212R1 SRG29.0H7-A01-F0512R1 SRG16.02Q+3-3-C01-F0512R1 SRL28.0H7-B01-F0512R1 SRL14.0H7-B01-F0512R1 Indexable Hole Diameter (mm) ø17.0 ø29.0 ø16.02 ø28.0 ø14.0 Reamer Hole Diameter Tolerance H7 H7 H7 H7 H7 Brazed Surface Roughness Ra/Rz Rz10.0 Ra0.8 Ra3.2 Ra3.2 Ra1.6 Others Circularity (μm) 5 2 − 5 5 Cylindricity (μm) 5 4 − 5 5 No. of Teeth 6 8 6 8 6 vc (m/min) 148 120 150 60 100 n (min-1) 2,772 1,318 2,982 682 2,230 fz (mm/t) 0.20 0.15 0.10 0.075 0.10 vf (m/min) 3,326 1,582 1,789 409 1,368 ap (mm) 0.10 0.15 0.15 0.15 0.15 Wet / Dry Wet Wet Wet Wet Wet Life, etc 57.9m 30.52m − 15.8m − J102
