Amount of Wear (mm) Cut-Off Small diameter cut-off TKF type Cut-off toolholders for automatic lathe great for high pressure coolant KTKF-JCT Finely breaks chips into small pieces. Superior chip control performance when machining difficult-to-cut material and stainless steel. Superior cooling action improves tool life. 1 Superior chip control performance Discharges coolant in two directions toward rake surface of insert. Finely breaks chips into small pieces. Coolant discharge structure comparison Coolant is directed from multiple angles to help shread chips into pieces １ 1 H ２ KTKF-JCT Competitor A Chip control comparison (Internal evaluation) SUS304 TAB6400 (Ti-6Al-4V) f(mm/rev) 0.01 0.02 0.03 f(mm/rev) 0.01 0.02 0.03 KTKF KTKF -JCT -JCT Competitor A Competitor A (Internal evaluation) Cutting conditions: Vc = 80 m/min, Wet (Oil-based) lubricating pressure: 1.5 MPa (Internal) Workpiece: ø12 mm 2 Superior cooling action improves tool life Coolant is directed from the flank face of the insert as well Wear resistance comparison (Internal evaluation) An ample supply of coolant to the tool edge area helps to further suppresse insert wear 0.14 0.12 KTKF-JCT 0.10 Competitor A 0.08 0.06 0.04 0.02 0 10 20 30 40 50 60 70 Cutting Time (min) Cutting conditions: Vc = 100 m/min, f = 0.02 mm/rev, Wet (Oil-based) Lubricating Pressure: 1.5 MPa(Internal) Workpiece material: TAB6400 (Ti-6Al-4v) φ12 H13
