新型超硬材料立方氮化硼复合聚晶体及其刀具,已经作为加工某些难加工材料的有效手段,在生产实践中开始得到使用。我厂加工碳钢热压板采用立方氮化硼刀具“以铣代磨”,取得了明显的经济效益。我厂热压板在产品配套中,数量多,每台有11～20块。板面尺寸大,面积为2.5～5m~2,在加工大平面的A_3碳钢板时,常规工艺按照粗刨—半精刨—精刨—磨削来加工平面,机床耗用时间长,工效低,工人劳动强度大,污染环境,且只能达到粗磨的水平。技术经济效益也低。采用立方氮化硼刀具“以铣代磨”加工后,获得之较高的加工精度和较低的表面粗糙度,而且刀具的使用寿命成倍乃至数十倍的提高,提高了
The new ultra-hard material cubic boron nitride polycrystalline polycrystalline and its cutting tools, has been used as an effective means of processing some difficult to process materials, began to be used in production practice. I plant processing carbon steel hot plate with cubic boron nitride tool “to milling instead of grinding,” made significant economic benefits. I plant pressing plate in the product package, the number of more, each has 11 to 20 blocks. Large surface size, an area of 2.5 ~ 5m ~ 2, in the processing of large flat A_3 carbon steel, the conventional process in accordance with coarse planing - planer - fine planing - grinding to process the plane, the machine consumes a long time, low efficiency Workers are labor-intensive and pollute the environment, and can only reach the level of rough grinding. Technical economic benefits are also low. The use of cubic boron nitride tool “to milling instead of” processing, access to the higher precision and lower surface roughness, and tool life doubled or even dozens of times to improve and improve
