蠕墨铸铁是一种介于球铁与灰铁之间的新型铸铁材料。具有较高的弹性模量,良好的耐磨性能。是生产机床主要部件较理想的材料。我厂应用于 DS-28日本牛头刨床、滑枕、床身、横梁、摆杆等部件。经强办切削试验,刚性好、热变形少、吸震性好,尺寸精度稳定,加工良好,受到日本客商好评。后又应用于 BL6063,B 6050牛头刨床。但是,蠕墨铸铁产生缺陷的倾向比较大,生产上不够稳定,使蠕铁的推广应 Compacted graphite cast iron is a new cast iron material between ductile iron and gray iron. Has a high modulus of elasticity, good wear resistance. Is the main part of the production of machine tools more ideal material. I plant used in DS-28 Japan calcined bed, ram, bed, beams, pendulum and other components. The strong do-cutting test, good rigidity, less thermal deformation, shock absorption, dimensional accuracy and stability, good processing, praised by Japanese merchants. Later applied to BL6063, B 6050 shaper. However, vermicular graphite cast iron tends to have defects and is not stable enough in production to promote the popularization of vermicular iron
