CITCO Borpax® PCBN Grade B25 – Recommended for high precision continuous hard turning Excellent for continuous cutting of a wide range of hardened steels and powdered metallurgy components from 45-65 HRC. Provides excellent tool life at cutting speeds up to 250 m/min. (800 ft./min.). The extremely uniform microstructure and consistency of the cBN material distributed throughout the ceramic binder facilitates high quality cutting edges. Precisionground edges (T-lands and hones) are capable of machining to sub-micron finishes. B25 is an extremely wear resistant material that offers a significant increase in tool life while retaining the integrity and hardness of the cutting edge. CITCO Diamond & cBN Products CITCO Borpax® PCBN Grade B26 – Recommended for high precision continuous and mild interrupted hard turning Suitable for cutting light to moderate interrupted hardened steels up to 65 HRC. Has shown improved performance at cutting speeds up to 200 m/min. (650 ft./min.). This is a low content, sub-micron grain cBN material with a titanium nitride (TiN) binder. B26 is a stronger, tougher material with improved chip resistance. This provides the highest quality cutting edges for the most demanding precision hard machining applications. High hot hardness and wear resistance deliver longer tool life while maintaining tight work piece dimensional tolerances. CITCO Borpax® PCBN Grade B31 – Recommended for excellent toughness behavior in heavily interrupted operations Optimum grade for toughness, demanding applications on hardened steels, tool steels, hard cast irons, gray cast irons, and powdered metallurgical components. High abrasion resistance for machining outlet valve seat alloys and alloyed work piece materials with high carbide content. Reliable and consistent performance on interrupted hard turning, milling and the most demanding applications. The material comprises over 90% cBN of 2-4 microns in size with a Cobalt-Nickel based binder. The combination of strength and toughness provides fine, smooth cutting edges which may be used up-sharp or honed. Positive geometry tools have minimal loss in edge strength. Sometimes desirable for fine precision finishing or where it is critical to minimize tool pressure.
