1 hard material matters Masterfinish -25Q

2 for optimum surface finish on aluminium components Smooth and clean component surfaces are not only a desired visual result, but often also a technical necessity. The production of smooth surfaces with minimum surface roughness causes high costs. This is mainly due to feed rate reduction of the turning tool, which results in considerably longer machining times. With CERATIZIT Masterfinish -25Q you will achieve smooth surfaces even with high feed rates. AlCuMg1 v c = 400 m/min f = 0,2 / 0,3 / 0,4 Rε = 0,8 a p = 0,5 / 1,5 / 3,0 R a = average roughness values -25Q Standard insert Benefit Considerably improved surface finish attainable with the same machining conditions Up to 35% higher feed rates whilst maintaining surface quality Reduced machining time and cost reduction 2
