New insert grade with reduced friction
- Published: July 24, 2018
Walter has introduced the WSM01 premier grade insert with Walter’s new MS3 negative geometry.
The WSM01 leverages HIPIMS PVD coating. Unlike standard PVD coating which deposits discrete droplets upon the target surface, HiPIMS (High Power Impulse Magnetron Sputtering) PVD coating produces very smooth surfaces, reducing friction in machining.
Walter says the new coating is characterized by excellent layer bonding and thickness distribution, reducing the tendency of ‘flaking.’ The smooth surface of the coating and sharp cutting edges keep edge build-up to a minimum and promote high surface finish quality.
This new insert is particularly suitable for machining unstable or thin walled components. The MS3 insert is equipped with jet guiding geometry to ensure optimum cooling directly on the cutting edge and is particularly suited to copy turning applications and medium machining applications in aerospace, automotive and general metalworking industries.
The combination of the WSM01 grade’s HiPIMS PVD hard layer and the new MS3 geometry is ideal for machining ISO S materials with difficult cutting properties such as high temperature alloys, titanium alloys, cobalt-based alloys, and nickel-based alloys such as Inconel 718. A secondary application of this new grade is with ISO material groups M (stainless steels), N (non-ferrous alloys such as aluminum and P (steels).
