New Super ZX Coat (PVD: P hysical V apor D eposition) P Employs our super multi-layered New Super ZX Coat, which utilizes our proprietary thin-layer coating technology and advanced nanotechnology. The coating consists of thousands of alternating, nanometer-thin (1 nanometer = 1 billionth of a meter) layers. Compared to conventional tools, the coating hardness has been increased by 40% and the oxidation starting temperature has been increased by 200°C.
Enables more than 1.5 times the machining speed and efficiency of conventional tools. Achieves more than double the tool life of conventional tools under the same cutting conditions Characteristics of the Coating Layer Wear Resistance Film Features Fracture Resistance
