Greenleaf Corporation has developed its WG-300, WG-600 and WG-700 whisker-reinforced ceramic inserts for machining high-strength alloy materials. Also available is the carbide TurboForm for thin wall components.
The WG-300 is intended to provide increased productivity in critical components, such as the jet engine. According to the company, it is capable of machining heat-resistant high strength alloy materials at eight times the production rate of traditional carbide cutting tools.
The WG-600 whisker-reinforced coated ceramic is designed for use in production. "It is a predictable insert grade that expands the speed envelope of WG-300 at the same federates, providing a new productivity range to the application," said a company spokesperson. "It is particularly suited to applications in which extended tool life is critical."
WG-700 was introduced to meet the needs of new developments in hot section materials for jet engines. "The new base material of WG-700, combined with a nano-layered 'platinum' coating, has met the challenge to productively machine the newest breed of materials such as Inco 718+ and other super alloys," said the spokesperson. "In standard high-strength materials such as Inco 718, cutting speed must be increased as well as the feed rates to get the maximum productivity out of the insert grade."
As the engines get lighter and lighter for fuel savings there are sections that become very thin. "A wall section of 0.050 inch (1,27 mm) in thickness is not an application for a ceramic cutting tool," said the spokesperson. "Carbide must be used as the cutting tool and controlling the chip becomes the paramount issue. The Greenleaf precision ground TurboForm insert utilizes a chipform that addresses the machining of the thin walls of new engine designs by reducing the cutting forces involved. Material chips are controlled at a range of depth of cuts down to 0.005 inch (0,127 mm). This design is a high positive-rake cutting edge in a negative-style insert for enhanced economy at high-performance levels. The TurboForm insert design, as well as other standard Greenleaf Corporation carbide grades such as G-925, G-920 and GA5026, are all excellent tools for the high-speed machining of high-strength alloys, titanium, high cobalt and stainless steel applications."
