标准范围

ISO 521:2011规定了具有圆柱柄和莫氏锥形柄的机器卡盘铰刀的尺寸。它涉及以下类型的铰刀:具有直径在1.32毫米至20毫米范围内的圆柱形柄的机器卡盘铰刀；直径范围为5.30毫米至50毫米的莫氏锥形柄的机器卡盘铰刀。对于每种类型的铰刀，ISO 521:2011给出了两个表格，一个显示了具有相应尺寸的优选尺寸，另一个是作为直径步长的函数列出的通用表格。还规定了长度、切割直径和圆柱柄直径的公差。

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.
