Tooling by DIJET Indexable Tools High Feed Diemaster SKSTyPE ■ CASE STUDIES 1. Machining tough die steel with bore for stamping die. Overhung length: 200mm Part name Stamping die Work Material SKD11 Hardness Raw material Tool No. SKS-4063R-08 Tool Grade WDMW080520ZTR, JC5040 Vc, (n) 178m/min (900min-1) Vf, (fz) 2,520mm/min (0.7mm/t) Cutting conditions Result ap (mm) 1mm Rough machining comparison among ae (mm) 40mm 3 competitors. Competitors got 60m & 90m tool life, SKS achieved 150m and Coolant Dry was still able to continue. Machine Vertical MC 2. Improved tool life on plastic mold. Roughing Metal removal rate: Q=115cm3/ Part name Plasticmold min Overhung length: 150mm Work Material NAK80 Pre-hardened steel Hardness 39HRC Tool No. SKS-4063R-10-22 (4N) Tool Grade WDMW10X620ZER, JC5118 Vc, (n) 138m/min, (700min-1) Vf, (fz) 3,200mm/min, (1.14mm/t) Cutting conditions Result ap (mm) 0.8mm Competitor‘s cutter (φ63-6N) got 80m tool life. After machining 160m, SKS ae (mm) 45mm showed normal wear (VB: only 0.09mm) and was still able to continue. SKS Coolant Air blow achieved over 2 times longer tool life compared with competitor‘s cutter. Machine Horizontal MC 3. Improved efficiency & tool life on forging die by modular head + carbide shank. Overhung length: 100mm Part name Forging die Radius cutter: Work Vf=2,800mm/min, ap=1mm, Material 1.2714 Hot work tool steel Q=70cc/min, Tool life: 45-60min/corner Hardness 285HB SKS:Q=122.5cc/min Tool No. MSH-3032-M16 + MSN-M16-55-S32C Tool Tool life: 190min/corner Grade WDMW06T320ZTR, JC5040 Vc, (n) 180m/min, (1,790min-1) Vf, (fz) 7,000mm/min, (3.9mm/rev, 1.3mm/t) Cutting conditions Result ap (mm) 0.7mm Improved the efficiency by 1.75 times and ae (mm) 25mm tool life by 3 times or more compared with Coolant Air blow radius cutter by combination of modular head + carbide shank.
