■ THE BEST CAST Especially in the automotive industry, but also in many other industrial sectors, the machining of cast iron is one of the most widespread and multi-faceted machining tasks. It ranges from machining conventional cast materials such as grey cast iron to the demanding new materials such as CGI (compacted graphite iron). At the same time, the user is making highest demands on accuracy and quality. For this most versatile of applications, Guhring supplies tools for every machining task including drilling, tapping and reaming as well as milling operations providing the customer...
