发布日期：2007-02
标准范围
This part of ISO 3338 specifies the dimensions of flatted cylindrical shanks for milling cutters — of diameters6mm to 20mm for single-flatted shanks,25mm to 63mm for double-flatted shanks and 6mm to 32mm for shanks with an inclined clamping surface. In the case of single-flatted shanks, it is applicable to both singleendedcutters 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 this part of ISO 3338 have the same dimensionalcharacteristics (diameters and lengths) but different tolerances on diameters, namely:— h8 for plain cylindrical shanks, commonly used for tools mounted in collets;— h6 for flatted cylindrical shanks, intended to be mounted in chucks and secured with a clamping screw, andrequiring an accuracy adjustment.
