5 micron / hour) the craft cycle that completely OK and contented industrialized economy produces asks. The applied Al2O3 coating of coating applies extensively at hard alloy razor blade, its advantage (if fight crescent moon exceedingly goodly,wear away depression and fight hot tearing function) already well known. Use CVD technology normally coating of deposit on hard alloy razor blade Al2O3. As a result of CVD craft higher deposit temperature can make the carbide in hard alloy becomes fragile, bring about bit to be machined in metallic cutting (basically be milling treatment) medium application is restricted. Asking to the tenacity of cutting blade taller treatment application is medium, skill of this kind of new work of PVD Al2O3 coating offers new treatment possibility for the user with its inferior deposit temperature. It is especially when milling stainless steel or difficult treatment material, compare with traditional PVD coating photograph, the function of new Al2O3 coating system can raise 2 times. Treatment spot checks the cutting test result with the earliest result to be published on magazine of Hauzer For You 10, performa AlOx-H appears first on EMO 2005 exhibition at that time. With manufacturer of other and main tool then a collaboration finished more tests to work. The test result that introduces to process X5CrNi1810 and 42CrMo4V workpiece data with Al2O3 coating cutting tool below reachs coating photograph. Experiment 1: Workpiece material: X5CrNi1810; Cutting tool: Razor blade of hard alloy coating; Cutting parameter: Vc=251.
32m/min, f=0.
15mm, ap=2.
5 Mm, ae=24mm; Cutting length: 600mm. By the life of Performa Alox-H of PVD coating razor blade and traditional coat razor blade contrast is seen, the life of Performa Alox-H of PVD coating razor blade raised 2 times. Experiment 2: Workpiece material: 42CrMo4V (DIN 1.
7225) ; Cutting tool: Razor blade of hard alloy coating; Cutting parameter: Vc=200m/min, f=0.
25mm, ap=2.
5mm, ae=20mm. By face of the knife after the razor blade when Performa Alox-H of PVD coating razor blade and workpiece of 42CrMo4V of milling of traditional coat razor blade the parallel case of average wear extent is knowable, when milling length is 4000mm, of Performa Alox-H of PVD coating razor blade hind knife face wears away to be reduced significantly than traditional coat razor blade.
