对经济和能源效率以及制造工艺的加工精度的要求越来越高，导致使用创新材料和生产技术。通过将矿物铸件用作机床的结构材料，一方面可以显著降低一次能源需求和制造成本。另一方面，矿物铸件的机械和热性能可以提高高度动态制造工艺的工艺可靠性和生产率。然而，化合物中石英骨料的硬度和耐磨性对具有几何限定的切削刃的矿物铸件的可加工性具有不利影响。高交变机械载荷和研磨工具磨损导致工具寿命短和制造成本高。尽管如此，具有几何定义的切削刃的矿物铸件的加工代表了根据客户特定要求设计和制造矿物铸件部件的关键驱动力。柏林工业大学机床与工厂管理研究所（IWF）进行了全面的切削试验，以分析超硬切削材料在加工矿物铸件时的一般性能行为。研究表明，切削材料的选择、刀具几何形状和工艺参数对矿物铸件加工的工艺可靠性有很大影响。第一个要求的过程为导向的工具设计的矿物铸件的有效加工已经制定。
Increasing requirements on the economic and energy efficiency as well as the machining accuracy of manufacturing processes lead to the use of innovative materials and production technologies. By deploying mineral casting as a construction material for machine beds the primary energy demand and manufacturing costs on the one hand can be reduced significantly. On the other hand the mechanical and thermal properties of mineral cast allow for an increase in process reliability and productivity of highly dynamic manufacturing processes. However, the hardness and wear resistance of the quartzitic aggregates in the compound have an adverse effect on the machinability of mineral cast with geometrically defined cutting edges. High alternating mechanical loads and abrasive tool wear lead to short tool life and high manufacturing costs. Nevertheless, machining of mineral cast with geometrically defined cutting edges represents a key driver for the design and manufacturing of mineral cast components according to customer specific requirements. The Institute for Machine Tools and Factory Management (IWF) at the Technische Universität Berlin performed comprehensive cutting tests to analyze the general performance behavior of super-hard cutting materials in machining mineral cast. The studies show that the choice of cutting materials, the tool geometry and the process parameters strongly affect the process reliability of mineral cast machining. First requirements of a process-oriented tool design for the efficient machining of mineral cast have been developed.
