The -RR93 chipbreaker boosts tool life, improves productivity, increases product reliability, enlarges chip-control working area and enhances surface finish. This new design replaces the -RR94 geometry.

 

The -R3 geometry excels in medium finishing applications in steels, difficult stainless steels and super alloys. Its optimally positioned grooves control chips even when depths of cut run as small as 1.5 mm, high feed rates range from 0.6 mm/rev to 1.2 mm/rev and cutting speeds reach 90 m/min. to 160 m/min. (Within these cutting-data ranges, the correct choices depend on materials and machine conditions.) The -R3 geometry replaces the previous -R2 geometry.

 

Throughout the RCMx range of inserts, the RCMT20-R2 positive screw-clamped range additions significantly reduce machining vibration, yielding smoother finishes ideal for the surface areas of railway wheel finishing and medium roughing applications of difficult materials. Dedicated insert edge treatments and retained functional toughness arrest comb cracks and increase edge security.

 

For improved mechanical and thermal properties that enhance performance, the Duratomic^® CVD aluminum-oxide coating process manipulates coating components at the atomic level. This technology's used-edge detection reduces cutting-edge waste.

 

The new -RR93 and -R3 geometries, as well as the Duratomic^® grades, have been tested in most common railway wheel materials, including R7, R8, R9, M1, Class B and Class C.
