MAPALPräzisionswerkzeugeDr. Kress KGAt large cutting diameters on the other hand, the limits of thePCD application range are primarily defined by the toolweight that, depending on the machine type, is only allowedto be max. 6 - 8 kg for automatic tool changing. In addition,moments of tilt have an unfavourable effect on the machiningresult during horizontal machining. These are caused by thetools’ own weight and the position of the centre of gravity.Postfach 1520D-73405 AalenContactHermann SteidleTelephone +49 / 73 61 / 5 85 – 1 24Fax +49 / 73 61 / 5 85 – 1 10e-mailmarketing@de.mapal.comDate 23.05.2011Specific developments at MAPAL are making largechanges to these limitsIn the meantime there are specific tool solutions for smalltools with tools for reaming and milling with cutting diametersbelow 3 mm and 6 cutting edges realised using the cuttingmaterial PCD. Solutions have also been realised in thisdiameter range for drilling tools, to some extent with rakefaces polished on both sides. For this purpose it wasnecessary, together with the PCD supplier, to develop PCDlayers up to 8.0 mm thick in excellent quality and with aparticle size matched to the machining. It has been possibleto master all the resulting challenges in production.The PCD is applied directly to the carbide tool body using aspecial brazing process. By means of special settingprocesses it is possible to accurately align cooling duct boresonly 0.3 mm in diameter through the PCD with the presinteredbore in the carbide tool body. The delicate PCDblade geometries are, if necessary, machined on a lasermachining system, the LASERPLUSS RayCutter.Press release no. 2011-05-10PresseinformationPress releaseCommuniqué de presseIn this way it has been possible to exploit new applications forPCD tools in the diameter range from below 3 mm to 6 mm.Here PCD tools are replacing carbide tools to some extent,an aspect that opens up major potential for savings for thecustomer. Also the increase in the number of cutting edges inthis diameter range signifies high potential for shortening thePage(s) 2 of 4
