在机床零件中套形零件如套筒、套管、钻套等是很多的,这类零件和别种零件比较起来有其独特之效。本文系根据实际生产所得资料,研讨套形零件的变形规律。 制造套形零件的材料一般都是中碳结构钢和中碳低合金钢,如45和40X号钢等;渗碳钢和高碳钢不常采用,用高合金钢制造套形零件则 Sleeve parts such as bushings, bushings, drill sleeves, and so on are many in machine tool parts. Such parts have unique features in comparison with other kinds of parts. This article is based on the actual production of information on the deformation of the nesting parts of the law. Materials used to manufacture sleeve-type parts are generally medium-carbon structural steel and low-carbon steel, such as 45 and 40X of steel; carburized steel and high-carbon steel are not often used, with high alloy steel sleeve parts
