Latest Patents
One of Sakari Ruppu's notable inventions is a coated cutting tool designed for the turning of steel. This cutting tool insert features a cemented carbide substrate composed of tungsten carbide (WC), 4-7 wt % cobalt, and 6-9 wt % cubic carbide-forming metals from groups IVB and VB, including titanium, tantalum, and niobium. The insert is characterized by a binder phase enriched surface zone with a thickness greater than 20 micrometers, preferably between 21 and 50 micrometers. The innovative coating consists of multiple layers: a first layer of Ti(C,N) that ranges from about 3 to 15 micrometers, followed by an alumina layer of α-Al2O3 of the same thickness, and a further layer of either Ti(C,N) or Ti(C,O,N) which measures from about 1 to 10 micrometers. The total thickness of the coating is maintained at less than 30 micrometers, ideally under 20 micrometers. This unique structure of the inserts provides excellent wear resistance and edge strength, making them highly effective for turning steel.
