It should be adjusted according to milling shape and machine type. ※3 ap:Axial Depth of Cut, ae:Radial Depth of Cut. ※4 Select a cutting fluid appropriate to work material, milling shape and machining content. ※5 Coolant supply and chip disposal in the deep portion are very important. ※6 Recommend to apply herical or ramping for approaching into axial direction. ※7 Reduction of feed and Depth of Cut to reduce machining load around side wall. ※ 8 For slotting, recommend reciprocating milling by adjusting feed at 80% of recommended milling conditions as a reference value. Recommend guide slotting process with short neck tool before milling with L/D 5 time or longer neck tool. ※9 Reduce both spindle speed and feed at same rate for chattering and also for insu cient spindle speed of a machine. ※ 10 Major adjustment of milling conditions, e.g. adjust spindle and feed speed at same rate, required on condition of a tool overhang length exceeding a shank diameter 5 times due to possible accuracy impact by chuck runout etc. 涂层Coating Square 长颈Long Neck Square 涂层Coating 长颈Long Neck O 树脂 Resin ○ O树脂 Resin ○ N 铜合金 Copper ○ N铜合金 Copper ○ N 铝合金 Aluminium Alloy ○ N铝合金 Aluminium Alloy ○ M 不锈钢 Stainless Steel ○ M不锈钢 Stainless Steel ○ H 高硬度钢 Hardened Steel 〜52 HRC ○ H 高硬度钢 Hardened Steel 〜52 HRC ○ 调质钢 P Prehardened Steel ◎ 调质钢 P Prehardened Steel ◎ P 合金钢 Alloy Steel ◎ P 合金钢 Alloy Steel ◎ P 碳素钢 Carbon Steel ◎ P 碳素钢 Carbon Steel ◎ 常规系列 无限涂层 长颈造型 MUGEN COATING Long Neck Type Regular Line 常规系列 无限涂层 长颈造型 MUGEN COATING Long Neck Type Regular Line 平底 平底
