RAL90 from Sandvik Coromant boosts aluminium machining

Designed for machining operations on high speed spindles, the system has a high strength tempered base body that increases flexural stiffness and natural frequency. Thanks to its high speed stability, RAL90 is said to allow manufacturers of challenging aero structure components made of aluminium copper, aluminium silicon, aluminium magnesium, aluminium zinc and aluminium lithium alloys to achieve excellent metal removal rates. A high precision insert seat with numbering ensures a maximum run-out accuracy of 20 micron axially and 15 micron radially, a feed rate of 0.3 mm/tooth and cutting depths of up to 14 mm. RAL90 is prepared for both MQL and high pressure coolant. Depending on diameter, speeds up to 35,000 rpm are possible. RAL 90 is available with cylindrical shank, screw coupling, HSK63A holding and TDA interfaces.
