本文详细介绍了金刚石工具和机械在三个主要领域取得的进展，特别是在花岗岩、采石、用于纪念性用途的石场加工和瓷砖制造方面。在石料场中，使用金刚石丝对砌块进行整平和剥落已成为一种公认的方法，并给出了与碳化硅线锯机相比的优势。加工花岗岩增长最快的方法之一是金刚石多刀片瓷砖切割机。讨论了各种机器系统和先进的工具，案例记录强化了机器、金刚石工具的技术数据，以及由此产生的生产率和工具寿命。

THIS PAPER DETAILS THE ADVANCES MADE WITH DIAMOND TOOLS AND MACHINERY IN THREE MAIN AREAS, WITH PARTICULAR REFERENCE TO GRANITE, QUARRYING, STONE YARD PROCESSING FOR MONUMENTAL USAGE, AND THE MANUFACTURE OF TILES. THE SQUARING AND SLABBING OF BLOCKS IN THE STONEYARD USING DIAMOND WIRE HAS BECOME AN ACCEPTED METHOD, AND THE ADVANTAGES OVER SILICON CARBIDE WIRE SAW MACHINES ARE GIVEN. ONE OF THE FASTEST GROWING METHODS OF PROCESSING GRANITE IS THE DIAMOND MULTI-BLADE TILE CUTTING MACHINE. THE VARIOUS MACHINE SYSTEMS AND ADVANCED TOOLING ARE DISCUSSED AND CASE HISTORIES REINFORCE THE TECHNICAL DATA ON MACHINES, DIAMOND TOOLS, AND THE RESULTING PRODUCTION RATES AND TOOL LIVES.
