高磷低合金球墨铸铁研磨平板是一种较新型的平板。它由合金熔炼浇注,经热处理和机械加工制成。与一般球墨铸铁相比,具有结构致密、硬度较高(一般HB 200左右)、切削锋利、生产效率高(可提高一倍以上)、嵌砂牢固,不易划伤工件、耐磨性能好、可使被加工件光洁度高等优点。高磷平板问世以来,被广泛应用于机械、光学、半导体元件等的高精度零件加工上。高磷研磨平板所用砂型没有苛刻的要求,国内生 High phosphorus low alloy ductile iron grinding plate is a newer type of flat. It is cast by alloy melting, heat treatment and machining. Compared with the general ductile iron, with a compact structure, high hardness (generally about HB200), cutting sharp, high production efficiency (can be more than doubled), embedded solid sand, not easy to scratch the workpiece, good wear resistance, So that the workpiece is polished finish higher advantages. Since the advent of high-phosphorus plate, is widely used in machinery, optics, semiconductor components such as high-precision parts processing. High-phosphorus grinding plate used in sand type is not harsh requirements, domestic students
