face milling in

cylinder head the cylinder head conveys air plus gasoline or diesel to the combustion chamber and serves as a cover for the cylinders in most four-stroke engines it also mounts the valves camshafts and work as framework for a number of other components it therefore needs to be strong and rigid thanks to the high thermal conductivity and low weight the cylinder head is normally alloyed with aluminium machining challenges the greatest challenge when machining cylinder heads is to minimize the cycle time and at the same time produce components with close tolerances and a defined surface quality deburring irregular tool wear and unpredictable insert tool-life typically provide long cycle times in the face milling operation solution – new face milling cutter the coromill® 5b90 is designed with a unique axial and radial positioning of the inserts which allows each insert to instantly cut chips efficiently without any insert adjustments each cutter is tailor made for each component

success story a spanish manufacturer of cylinder heads for passenger car engines asked sandvik coromant for help the machining process was unstable and they had problems with burr another problem was the unpredictable insert tool-life which depended on the cartridge adjustments that differed slightly from set-up to set-up challenge provide a stable and burr-free machining process with predictable insert tool-life the arrows show the most critical areas for remaining burr quality requirements rougness r 4 rmax 20 waviness w 4 flatness 0.05 solution the coromill® 5b90 cutter offered a smooth finishing operation with predictable wear and no burr as the cutter provides thin chips they are easily removed from the component to avoid damaging of the face in the subsequent operation yearly savings 21 000 € existing cutter coromill® 5b90-cutter number of teeth zn 16 9 cutting speed vc 3140 m/min 3800 m/min spindle speed n 5000 r/min 6000 r/min feed rate vf 8280 mm/min 9000 mm/min

keep the green light on when producing a large series of components the most important success factor is high machine utilization when the machine is running at full capacity it is making money and drives your business forward we call it green light machining automotive transmission components are often slender and have a complex design that is difficult to clamp as the level of automation is usually high a rigid and secure machining process is key to succed low alloy steel is the traditional raw material for transmission components that can be case hardened through a heat treatment process other materials include powder metals cast iron and low carbon steel green light machining of many transmission components can be challenging but we have quite a few solutions at hand head office ab sandvik coromant se-811 81 sandviken sweden www.sandvik.coromant.com e-mail info.coromant@sandvik.com c-2940:156 eng/01 © ab sandvik coromant
