Miniature tools need to be highly precise and reliable. This is because they have to cope with demanding materials and, what’s more, do this with small tool diameters and tolerances in the μm range. Zecha Hartmetall-Werkzeugfabrikation GmbH in Königsbach-Stein has developed a tool range for such applications that is perfectly tailored to the demands of micro machining.
The manufacture of miniature parts and components requires the observance of extremely low tolerances and thus the assurance of the highest possible precision. That increases the challenges for the quality of the tools used enormously – not least when it is all about economic and precise micromachining of titanium alloys and stainless steels.
Extensive range of micro tools
Zecha Hartmetall-Werkzeugfabrikation GmbH, the specialist for micro machining, supplies the market with five high-performance cutter types that always ensures the best results for such micro machining applications. Arndt Fielen, Head of Sales at Zecha: “Day-in, day-out, we are contacted by users who would like to implement a specific, usually demanding machining task both fast and efficiently. Our micro cutters, for example in the series 471, 472 and 473, help to ensure superb results in high precision fields such as the medical and timepiece industry, for circuit board cutting or in micro component and turning processing!”
Large choice in application
The Zecha microcutters offer polished flutes, a minimum protective chamfer and innovative TIAIN thin coats. This enables not only absolutely burr-free surfaces on titanium and stainless steel but also impressive life cycles. Zecha supplies the cutters in the series 471, 472 and 473 in several variants and in diameters of 0.20 to 0.80 mm, tailored to the specific application in question. The Series 471 is a straight toothed single cutter. It is particularly suited for the milling of high precision geometric micro structures with high frequency spindles at high speed ranges. Moreover, its short flute length offers maximum stability during roughing operations. The tools in the Series 472 come with a long or short flute. They have been conceived as double cutters with spiralled swarf chambers and are intended for the series manufacture of small components with optimum tooth feeds. The long version also guarantees the highest surface qualities and clean finish. Cutters in the Series 473 have been configured as triple cutters with spiralled chambers and short or long flute – just the right performance to work swiftly and powerfully at medium speed rates.
Minimum radii, maximum precision
Micro machining follows its own laws that can be fulfilled only with the know-how of experts. Ultra-fine ground geometries, systematic high-class quality and the longest possible life cycles are the recipe with which Zecha provides its customers with the key advantage in the minimum tolerance machining.
