9、or Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has th

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The proce

28、rmative) Recommendations for use and applicationA.1 Clamping systemThe clamping system should be specified by the manufacturer of the receiver or machine tool spindle. The system should provide sufficient clamping force to ensure contact of the shank flange with the receiver face, as well as seating

29、 the taper by elastic deformation.A.2 Clamping forcesVariations of taper shank and -receiver size within the specified limits of tolerance will cause the portion of the clamping force acting on the flange surface to vary. However, the clamping forces given in Table A.1 will ensure that the portion o

30、f acting on the flange surface is never less than 80 % of the total. The flange contact is decisive for the stiffness of the polygonal taper interface.Table A.1 Clamping forceNominal size, mm 32 40 50 63 80 80X 100Clamping force, kN 15 20 25 30 40 40 60Lower clamping forces can be sufficient when op

31、erational loads are low (e.g. cutting forces in finish machining). Conversely, higher clamping forces can be required when high operational loads are encountered (e.g. cutting and feed forces in heavy machining).A.3 Information about speeds, torques, bending loads and stiffnessThe manufacturer shoul
