FAQs ABOUT ZERO-POINT CLAMPSAND THE AMF ZERO-POINT SYSTEMWHAT IS PULL-IN FORCE / HOLDING FORCE?> The pull-in force describes the force with which the nipple is pulled in and clamped with positiveinterlocking in the clamping module. The holding force, in contrast, specifies the maximumpermissible pull force of the engagement nipple screw.WHAT IS REPEATABILITY?> The repeatability specifies the tolerance range within which the recorded reference points on theworkpiece lie after removal and reclamping of the same workpiece. The repeatability, also calledrepetition accuracy, is below 0.005mm.WHAT ADVANTAGES RESULT FROM THE USE OF ZERO-POINT, SLIT AND UNDERSIZE NIPPLES?> These different types of nipples offset the spacing tolerances of nipples and clamping modules.The fixed reference point is achieved through the zero-point nipple; the slit nipple serves tocompensate for the still-free axis. The undersize nipple does not have a centring function, butonly a clamping and holding function.CAN I INSERT THE CLAMPING NIPPLE DIRECTLY INTO THE WORKPIECE FOR MACHINEPROCESSING?> The high costs for chucking fixtures and workpiece clamping can be effectively saved here if theclamping nipples are mounted in the workpiece, which is clamped directly using the clampingmodules. As a result, a complete 5-sided processing of the workpiece is possible in onechucking. With the different nipple sizes (attaching thread M6 to M16), workpieces of differentsizes can be clamped..HOW DOES THE SYSTEM COMPENSATE FOR HEAT, SUCH AS FROM METAL CUTTING?> Through the different clamping nipple designs, the system can compensate for temperaturedifferences between the workpiece and the clamping module easily and controllably. For agraphic depiction of the nipple array, see page 47 of the catalogue. If you have other technicalquestions, please contact us at any time.WHAT SHOULD BE THE SPACING TOLERANCE OF THE CLAMPING NIPPLES AND THECLAMPING MODULES IF SELF-PRODUCED?> The recommended spacing tolerance of clamping nipples and clamping modules is +/- 0.01mm.Subject to technical alterations.10 Zero-Point-Systems ANDREAS MAIER FELLBACH ∙ www.amf.de
