PCD TURNING INSERTS WITH NS CHIPBREAKER NOW OFFERING 0.1 AND 0.2 MM NOSE RADII

For years, high-speed aluminium machining with PCD inserts presented significant advantages, but a chip control challenge persisted – until now. Introducing Tungaloy’s cutting-edge ablating technology, which has enabled the development of our sophisticated NS chipbreaker geometry directly on the PCD tip surface. With a specialized rake face and chip redirector designed for 0.1 and 0.2-millimetre nose radii, the NS chipbreaker guarantees reliable and consistent chip forming and evacuation in all aluminium alloy part machining that spans from finishing to light-roughing operations.

A total of fifteen new 0.1 and 0.2-millimetre nose radius PCD inserts have been added with NS chipbreaker. All new inserts are in Grade DX110. Extremely wear-resistant, this submicron grain-sized PCD grade provides the insert with strong edge security that promotes superior surface finishing quality and process stability. These new inserts are designed to eliminate birdnesting of chips in machining applications with small corners, shoulder fillets, or undercuts requiring 0.2mm or smaller radii. They are also ideal for finishing applications requiring a close tolerance and high surface quality after a light depth-of-cut pass, in which excellent chip breaking and control are vital. Typical part samples include precision aluminium parts for automotive, optical equipment and instruments, and artificial intelligence robotic system industries.
