铣刀圆柱直柄.第2部分:平头圆柱直柄的尺寸特性

[中文适用范围]： ISO 3338的本部分规定了铣刀用扁圆柱柄的尺寸，单扁柄直径为6mm至20mm，双扁柄直径为25mm至63mm，带倾斜夹紧面的柄直径为6mm至32mm。 对于单扁柄来说，它既适用于单端刀具，也适用于双端刀具，因为双扁柄不能容纳单端刀具。 [外文原描述]： ISO 3338-2:2013 specifies the dimensions of flatted cylindrical shanks for milling cutters, of diameters 6 mm to 20 mm for single-flatted shanks, of 25 mm to 63 mm for double-flatted shanks and of 6 mm to 32 mm for shank with inclined clamping surface. In the case of single-flatted shanks, it is applicable to both single-ended cutters and double-ended cutters, as double-flatted shanks cannot admit single-ended cutters. The dimensions of plain cylindrical shanks and threaded shanks are given in ISO 3338-1 and ISO 3338-3, respectively. The two shank types covered by ISO 3338-1 and ISO 3338-2:2013 have the same dimensional characteristics (diameters and lengths), but different tolerances on diameters.
