Originally titled 'Cut UD4 Insert Geometry Boosts Reliability and Productivity '
Walter Cut UD4, an insert geometry for radial grooving and groove turning in the automotive and metalworking industries, delivers maximum process reliability, optimum chip formation, high levels of productivity and reduced tooling costs, the company says.
The Walter Cut UD4 features a multifunctional chipbreaker design that is said to provide excellent chip control, thanks in part to its double geometry that delivers a large application area. It has a strong 0-degree primary chamfer that strengthens the cutting edge, a silver surface that makes for easy wear detection and full usage of cutting edges. It also features a coating that delivers low fiction and better wear resistance.
With a standard PVD coating, there is typically a high rate of heat transfer into the cutting tool insert substrate, which leads to higher wear rates. With the Walter Cut UD4 Tiger·tec Silver PVD Al2O3 coating, there is less heat in the substrate, leading to high tool life, reduced tool and tool change cost, increased process reliability and high productivity.
The main application area for the UD4 is grooving and groove turning on forged materials such as transmission components, gears and shafts. IT works especially well in low carbon steels where chip control is a particularly big challenge. Targeted workpiece materials are steel and cast iron (ISO P and ISO K).
