17、Dimensions and designation of shanks1 ScopeThis part of ISO 26623 specifies dimensions for polygonal taper interfaces with flange contact surface polygon-shanks for automatic and manual tool exchange to be applied on machine tools (e. g. turning machines, drilling machines, milling machines, and tur
18、n/milling centres, as well as grinding machines). A range of shank sizes is specified.These shanks incorporate a grooved flange to enable automatic tool exchange. The clamping can be realized by a circular groove using clamping segments or internal screw threads using centre-bolts.The torque is tran
19、smitted by form lock (polygon).2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

37、s 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 of acting on the flange surface is never less than 80 % of the t
38、otal. 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 operational loads are low (e.g. cutting forces in finish machinin
39、g). Conversely, higher clamping forces can be required when high operational loads are encountered (e.g. cutting and feed forces in heavy machining).A.2 Information about speeds, torques, bending loads and stiffnessThe manufacturer should provide information regarding permissible speeds, torque tran
40、smitting capacities, bending loads, and stiffness.A.3 Information about material and heat treatmentThe polygonal taper shanks should be heat treated with considerations for strength, hardness, and case depth (if not through hardened). Toughness and wear requirements are to be taken into consideratio
41、n.The coupling could be either through hardened or surface hardened depending on what is suitable for the range of application.A.4 General surface hardness recommendationsTapered polygon, internal clamping groove, and axial contact surface: HRC 42 min.

42、lancingIf the polygonal taper shank requires balancing before tools or equipment are assembled on to the shank, it may be balanced with a hole located according to Figure A.1 and Table A.2.NOTE The balancing hole is exclusively used for compensation of coolant hole and orientation recess on the poly
43、gonal taper (balanced by design). The data chip hole has not been taken into consideration.If post assembly balancing is needed, it should be confined to the preferred balancing zone as shown in Figure A.1 and Table A.2.
