3、spindle nose with which it is to be used. The range of nominal sizes is as follows : 8, 10, 12, 16, 20, 25, 28, 36 and 48 mm. 4.2 Interchangeability Adaptors shall be capable of fitting spindle noses manufactured in accordance with clause 3. 1 Copyright International Organization for Standardization

9、the Woodruff key. 4.7 Locking screw (for nominal diameters 16 to 48) For reasons of safety, it is important that the locking screw when tightened does not protrude beyond the outside diameter of the knurled portion of the nut. Locking screws are therefore to be reduced in length if necessary so that
10、 they do not pro- trude when the nut is locked. 4.8 Lead-in of the adjustable adaptors in the spindle noses For types A and B, a suitable form of lead-in shall be machined on the closed end of the adaptor body, to facilitate insertion into the spindle nose. 4.9 Marking The body of the adaptor shall
11、be marked with the type, nominal size, size of Morse taper and, for type B adaptors only, the extension length.
