带有柱柄和莫氏锥度摸柄的机用铰刀

[中文适用范围]： 本国际标准规定了带圆柱柄和莫氏锥柄的机用铰刀的尺寸。它涵盖了以下类型的铰刀：带圆柱柄的机用铰刀，直径范围为1.32毫米至20毫米；带莫氏锥柄的机用铰刀，直径范围为5.30毫米至50毫米。对于每种类型的铰刀，本国际标准提供了两个表格，一个显示优选尺寸及其相应尺寸，另一个是以直径步长为函数的通用表格。还规定了长度、切削直径和圆柱柄直径的公差。 [外文原描述]： ISO 521:2011 specifies the dimensions of machine chucking reamers with cylindrical shanks and Morse taper shanks. It deals with the following types of reamer: machine chucking reamers with cylindrical shanks in the range from 1,32 mm to 20 mm diameter; machine chucking reamers with Morse taper shanks in the range from 5,30 mm to 50 mm diameter. For each type of reamer, ISO 521:2011 gives two tables, one showing preferred sizes with corresponding dimensions, and the other being a general table set out as functions of diameter steps. Provision is also made for tolerances on lengths, cutting diameters and the diameters of cylindrical shanks.
