Grooving Wear (mm) External grooving GBF type KGBF-JCT (for automatic lathe) Discharges coolant from the top of the insert Cutting Area Distance Coolant hole (~10mm) Ample supply of coolant to the cutting edge. Prevents coolant stream spreading which slows the coolant flow. Direction of supply Sufficient coolant between the chipbreaker and the chips Stable chip curls and sufficient cooling of the insert G 1 Excellent chip control provide long tool life Chip control comparison (internal evaluation) KGBF-JCT provided much better chip control with reducing chip clogging KGBF-JCT Competitor B Chip clogging Chip clogging Chip clogging 0.04 0.06 0.08 0.10 f (mm/rev) Cutting conditions: Vc = 100 m/min, d = 2.5 mm, GBF32R200-010 PR1535, KGBFR1625H-16F-JCT Workpiece material: TAB6400 (Ti-6Al-4V) External coolant + Internal coolant (1.5MPa) External grooving 2 Superior cooling action improves tool life Wear resistance comparison (internal evaluation) KGBF-JCT showed superior wear resistance 0.20 KGBF-JCT Competitor B 0.15 Cutting edge condition 0.10 KGBF-JCT Competitor B 0.05 Fracture 0.00 0 15 30 45 60 75 90 Cutting Time (min) Cutting conditions: Vc = 150 m/min, d = 1.8 mm, f = 0.06 mm/rev, GBF32R100-005GL PR1535, KGBFR1625H-16F-JCT Workpiece material: SUS304 External coolant + Internal coolant (1.5MPa) External grooving G20
