使用热压陶瓷刀具,可使导辊的槽加工成本减少92%。这是NGk Spark plug公司用HC_2陶瓷刀具取代一般的CBN烧结刀具取得的突出成效。CBN烧结刀具平均一个刀片加工200个工件,而陶瓷刀具可加工150个工件。但陶瓷刀具与CBN刀具相比,前者的成本便为后者的1/8,因此,可大大降低成本。如用CBN刀具一天生产1200个导辊,每把CBN刀具80美元,共需用六把,一天共耗刀具费用480美元。
The use of hot-pressed ceramic tools reduces the cost of guiding the grooves by 92%. This is an outstanding result achieved by NGk Spark plug company replacing conventional CBN sintering tool with HC_2 ceramic tool. On average, CBN sinters process 200 workpieces per blade while ceramic tools can process 150 workpieces. However, compared with the CBN cutting tool ceramic, the former cost will be the latter 1/8, therefore, can greatly reduce costs. Such as the use of CBN cutter production of 1200 guide rollers a day, each CBN cutter 80 US dollars, a total of six required a day a total cutter cost 480 US dollars.
