Mounting hole dimensions and markings1 ScopeThis part of GB/T 33524 specifies automatic tool changers and manual tool changers (such as lathes, drill presses, milling machines and milling centers). Mounting hole series size for modular conical interface with steel ball tensioning system. Torque transmission is achieved by the friction of the shank tail, the clamping elements and the keys.2 Normative referencesThe following documents are indispensable for the application of this document.

This interface torque transfer capability will increase as the clamping force increases. Refer to Appendix A for the reference value of the clamping force of the module taper mounting hole.5 markThe module cone mounting holes that conform to this section are marked as follows. a) "module taper mounting hole"; b) the standard number (eg “GB/T 33524.2”); c) codename "TS"; d) Nominal size in millimeters. Example. Module taper mounting holes with a nominal size of 63 mm are marked as. Module cone mounting hole GB/T 33524.2-TS63Appendix A(informative appendix) Application recommendation A.1 clamping force A change in the force range of the module taper shank and the module mounting hole causes a change in the pressing force acting on the flanged shank contact surface. This It has a decisive influence on the rigidity of the modular conical interface with a steel ball tensioning system. The range of clamping force is given in Table A.1. The values in Table A.1 are for use only with modular cone mounting holes with steel ball tensioning systems. Table A.1 Scope of clamping force Nominal size Mm 32 40 50 63 80 100 Minimum clamping force kN 9 13 22 36 53 75 Maximum clamping force kN 18 27 40 58 80 110 When the running load is small (for example, finishing cutting force and feed force), the minimum clamping force is sufficient. Conversely, when the running load is large (for example, heavy cutting machining force and feed force), a large clamping force is required. Note. The mechanical stress is derived from the clamping force and the locking mechanism design. A.2 Information on permissible speed, torque, moment load and stiffness Manufacturers should provide information on allowable speed, torque transmission capability, bending load and stiffness. A.3 Materials and heat treatment For the material and heat treatment of the module taper mounting hole, the strength, hardness, toughness and wear resistance requirements should be considered. Recommended hardness is not less than 48HRC. Usually the hardness of the mounting holes should be higher than the hardness of the shank. 2-22662 OSI/ 7102- 2 42533 T/ ......Source: Above contents are excerpted from the full-copy PDF -- translated/reviewed by: www.ChineseStandard.net / Wayne Zheng et al.
