LDP—J—CFⅡ型立方氮化硼复合刀具是我所于1683年12月通过四川省科委鉴定的最新牌号的立方氮化硼刀具。此种刀具采用了多种措施,使之在刀片强度,硬度,复合面的粘结牢度方面都有很大的提高。受年会的邀请在会上表演了用LDP—J—CFⅡ型刀具加工高耐磨铸铁轧辊(φ300×1000mm)。轧辊毛坯有明显的目视砂眼。粗车:用氮化硅刀具仅切削10mm 即明显磨损。而用LDP—J—CFⅡ型刀片一把刀就将毛坯表皮连续车光〔V>100米/分,S=0.09 t=0.3—0.4〕。精车:连续切削两小时以上刀具没见明显磨损(V>100米/分,S=0.09,毫米/转t=0.2毫米),加工表面光洁度为▽9左右,在灯光下呈
LDP-J-CF Ⅱ type cubic boron nitride composite tool is our latest in December 1683 by the Sichuan Provincial Science and Technology Commission identified the latest brand of cubic boron nitride tool. This tool uses a variety of measures to make the blade strength, hardness, the bonding surface of the composite surface has greatly improved. At the invitation of the annual meeting, a high-wear-resistant cast iron roll (φ300 × 1000 mm) was machined with a LDP-J-CF Ⅱ cutter. Roller blank has obvious visual trachoma. Crude: Only cut with silicon nitride cutter that is significantly wear 10mm. The use of LDP-J-CF Ⅱ blade knife will be a rough car skin continuous car light (V> 100 m / min, S = 0.09 t = 0.3-0.4〕. Finished car: No cutting (≥100 m / min, S = 0.09, mm / rev t = 0.2 mm) for tools cut more than two hours in a row. The finish of the machined surface is about ▽ 9,
