New geometry, grade combination for difficult to cut materials
- Published: April 24, 2017
Walter USA has introduced a new cutting geometry, the MS3, teamed with a new high tech grade, WSM01.
The new WSM01 grade, manufactured using the HiPIMS (high-power impulse magnetron sputtering) method, provides smooth surfaces that are characterized by excellent layer thickness, outstanding layer bonding and high level wear resistance, says Walter.
The combination of the HiPIMS PVD coating and the new MS3 geometry is ideal for machining ISO S materials with difficult cutting properties such as high temperature alloys, titanium, cobalt-based and nickel-based alloys. Secondary applications for this new grade/geometry combination are steel, stainless steel and non-ferrous material groups (ISO P, M and N).
Negative inserts with MS3 geometry are available with both sintered and fully ground circumference. Their smooth surface and extremely sharp cutting edges keep build up to a minimum and ensure a high quality surface finish. This makes it significantly easier to reliably manufacture burr-free components.
The new insert is particularly suitable for machining unstable or thin-walled components and setups with long overhangs, since its highly positive geometry provides low cutting pressure and prevents vibration. The MS3 insert – much like Walter's RM5 – is equipped with coolant jet guiding geometry to ensure optimum cooling directly on the cutting edge. It is well-suited to turning applications and to medium machining applications in the aerospace industry, medical components manufacturing, general mechanical engineering and the automotive industry.
