The tried-and-tested PEACOCK mill cutters from ZECHA Hartmetall-Werkzeugfabrikation GmbH are the go-to tools for achieving fine contours in the HSC processing of highly alloyed and hardened steel up to 67 HRC.

They effortlessly ensure precision, stability and smooth surfaces in different areas of application, particularly in mould making. A new family member, the 599 series, offers additional support for the mill cutters 581P, 583P and 597P.

The new mill cutter series offers ideal machining preconditions for a vast number of materials, material hardness values and alloying components such as, for example, powder metallurgical steels, tungsten copper, nickel-chromium alloys and cobalt chromium. Its special tool properties make the new family member eminently suitable both for finishing as well as roughing and its flexible and versatile properties can find efficient application in mould and tool making, the automotive and aerospace industries, light engineering as well as in medical technology.

The PEACOCK expansion contains ball and torus mill cutters with two or four flutes that will be gradually taking over the hard machining role from the well established 581H and 583H lines in Zecha's comprehensive tool range. The two-flute ball cutters are available in diameters 0.2 mm - 6.0 mm, whereas the four-flute variants in the 599 series come in selected dimensions with a diameter ranging from 3.0 mm to 6.0 mm. The torus mill cutters are available with two flutes in diameters 0.2 mm - 0.8 mm.

If the machine operator wants to turn to a four-flute torus mill cutter, he can choose between diameters from 1.0 mm to 6.0 mm. Irrespective of whether two or four flutes, torus or ball cutter - all boast precise cutting performance down to the core.

Robust tool despite high stress

The adaptation of the micro-geometry combined with a new geometric design created by the internal development department produces optimum results. The special groove geometry of the mill cutters reduces forces and friction. Thanks to the shaft, geometry - no sharp edges and corners - greater stability and milling depths are possible. The stresses occasioned by high temperatures during robust machining can be avoided almost completely due to the easy cutting construction and the high-end coating technology. The chips are quickly removed with the aid of the smoothly polished chipping spaces and the process temperature can be very well controlled. The 599 series mill cutters can also be used for machining of high wear-resistant super alloys containing chromium by means of KSS emulsions, as they are both suitable for dry and wet processing. They also achieve very good results regarding surface quality.

Conclusion: PEACOCK is an all-round talent!

As with the entire PEACOCK family, the micro-geometry of the mill cutters ensures high precision during hard machining. Apart from significant life cycle increases due to the stable shaft and cutting geometry, the WAD-coated mill cutters achieve excellent surface qualities. In addition, the micro mill cutters, configured for shape and concentricity accuracies of 0.005 resp. 0.003 mm, guarantee a high dimensional precision of the component. Not to be forgotten are the highly detailed recording of all work processes as well as the identification number at the end of the shaft of the mill cutters that enable exact reproducibility.
