2 DIJET Industrial Co., Ltd. Possible to high precision and high efficient machining for aluminum, stainless steel and titanium alloy in aerospace tooling. Adopting high precision design enabled minimum deflection and high accurate machining True 90 degrees shoulder milling Multi-purpose milling is possible: face milling, shoulder milling, slotting, ramping and helical interpolation Insert has key for high velocity revolution specification Internal coolant supply Adopted “G-body” High metal removal rate: Q=2,250cc/min by 50 dia.(aluminum alloy) 15mm

3 DIJET Industrial Co., Ltd. ⇒ Equal performance 4,000N Dijet-MAL Competitor B Cutting force (N) 4,000N Feed force Main force Back force Total force Machine power (kW) Power (kW)

4 DIJET Industrial Co., Ltd. ビビり小ビビり大 Dijet-MAL Competitor B Big chattering Stable cutting Cutting force (N) Feed force Main force Back force Total force 4,000N ⇒ Cutting force of Aero-Chipper was 25% ～ 50% less than Competitor B.

5 DIJET Industrial Co., Ltd. ・ Aero-Chipper showed much precise dimension on insert than Competitor B. ・ Dijet MAL ： φ25 （ G-body modular head ） 15mm Actual diameter (mm) Nominal diameter:25mm Measuring location (mm) Competitor B

A5056 n=20,000(min-1) Vc=1,570(m/min) ap=15(mm) ae=3(mm) Wet,Down Cut 15mm 3mm ・ Dijet MAL ： φ25 （ G-body + Carbide shank ）・ Competitor B ： φ25 Measuring location (mm) Remains Over cut (μm) Measuring location (mm) B B ・ During 15mm cutting length, Aero-Chipper showed 4 times better accuracy.

7 DIJET Industrial Co., Ltd. Vc ＝６０ｍ /min Ｆｚ＝０．２ mm/ ｔｘ６ N Ap ＝１ mm Ae ＝４０ｍｍ Vc ＝４０ｍ /min Ｆｚ＝０．１ mm/ ｔｘ５ N Ap ＝８ mm Ae ＝４０ｍｍ Work material:Ti-6Al-4V （ 41HRC) / Tool dia.:63 HDM Aero-chipper Metal removal rate (cc/min) Twice High efficiency

8 DIJET Industrial Co., Ltd. Aero-Chipper removed Q=2,250cc/min. Low spindle load and good surface finish. Makino Aluminum NONE GOOD WET GOOD Pocket milling Box Work size : 580X600X760

9 DIJET Industrial Co., Ltd. Makino Aluminum Aero-Chipper removed Q=480cc/min. Insert showed good wear resistance and good surface finish. NONE GOOD Rough and Finishing milling Body WET Arber : DSA BT50H
