ROUND TOOLS NORTON WINTER PRECISION TECHNOLOGY TOOL GRINDING / 15 DIAMOND & CBN GRINDING WHEELS FOR FLUTE GRINDING Flute grinding is the most time-consuming and thus most cost-intensive manufacturing step during drill and end mill production. It is necessary to optimise the machine and cooling lubricant systems as well as the abrasives. In recent years, machines have become more compact, spindle power has increased, axis paths have been reduced and machine controls have become more efficient. At the same time, Norton Winter has developed flute grinding tools which meet these increasing requirements and which now enable the improved machine capacity to deliver a higher and more economic output. Matched to the application and the system environment, innovative Norton Winter flute grinding wheels are always the best solution. Grinding wheels in the Q-Flute range have proved to be particularly useful for standard tools. The combination of excellent free-grinding behaviour and profile retention allows economic flute grinding with high feed rates. Q-Flute grinding wheels can also be dressed on the grinding machines. Mini and micro tools require bond systems with exceptional edge stability. Norton Winter metal bonds and high-performance resin bonds are the number one choice here. edge stable Clearance grinding profilable Standard tools Mini tools WHEEL WEAR (%) Low Wear Low Forces High Wear 60 50 60 70 GRINDING FORCES (%) 80 90 100 120 130 70 80 110 90 100 120 130 150 Q-Flute 2 Competition Q-Flute EVO Q-Flute XL40 140 110
