Technical Information for Solid Endmills for Aluminum Good chip evacuation and fine resistance for built up edge Solid Endmills for Aluminum Good surface finish with minimized cutting load and built-up edge occurrence DLC coating - Higher hardness (Hv3000-7000), About 3 to 6 times longer tool life comparing uncoated endmill - Fine surface roughness on workpiece with excellent lubricative effect by low friction co-efficient (u 0.1) Superior in Aluminum, Aluminum alloys, Copper and Copper alloys O Features of copper & aluminum machining Built-up edge is easily generated though the workpiece has low cutting resistance and chip-removal is fine As it has high coefficient of thermal expansion, deflection degree due to machining heat is huge, and it also influences to workpiece quality and residual stress While machining, chips can easily damage on the workpiece's surface as the workpice has low hardness, and tool life is over due to flank wear in general O Trouble shooting for copper & aluminum machining Use a higher rake angled tool with sharper edges, and minimizes cutting load and built-up edge generating by using oil (MQL) mist Increase Vc and reduce the depth of cut for a better surface finish and productivity O Recommended cutting conditions (SSEA2000) Workpiece Shouldering Slotting Aluminum alloy (A7075) Aluminum alloy (cast) (AC4B) Aluminum alloy (A7075) Aluminum alloy (cast) (AC4B) Condition R.P.M n (min'1) Feed vf (mm/min) R.P.M n (min’1) Feed vf (mm/min) R.P.M n (min-1) Feed vf (mm/min) R.P.M n (min1) Feed vf (mm/min) Diameter (0) 1 40,000 480 40,000 368 40,000 368 40,000 280 2 40,000 880 38,000 680 38,000 680 32,000 440 3 32,000 1,120 25,000 760 25,000 760 21,000 480 4 24,000 1,200 19,000 800 19,000 800 13,000 520 5 19,000 1,280 15,000 880 15,000 800 13,000 560 6 16,000 1,520 13,000 960 13,000 880 11,000 600 8 12,000 1,520 9,500 960 9,500 960 8,000 640 10 9,500 1,520 7,600 960 7,600 960 6,400 640 12 8,000 1,520 6,400 960 6,400 960 5,300 640 16 6,000 1,520 4,800 960 4,800 800 4,000 576 20 4,800 1,200 3,800 800 3,800 776 3,200 528 Application tip Shouldering depth (ap) and radial deoth (ae) ap: s 2.0D ae: s 0.2D (D 03) : s0.5D (Da03) 0D Jap Slotting depth (ap) ap: s D (max: 12 mm) Workpiece should be clamped rigidly In case of vibrations, reduce R.P.M and feed rate by the same ratio Endmills J. 37
