FAQS ABOUT ZERO-POINT CLAMPS AND THE VEKTEK ZERO-POINT SYSTEM
WHAT IS PULL-IN FORCE / HOLDING FORCE? > The pull-in force describes the force with which the stud is pulled in and clamped with positive interlocking in the clamping module. The holding force, in contrast, specifies the maximum permissible pull force of the engagement screw. WHAT IS REPEATABILITY? > The repeatability specifies the tolerance range within which the recorded reference points on the workpiece after removal and reclamping of the same workpiece. The repeatability, also called repetition accuracy, is below 0.005mm. WHAT ADVANTAGES RESULT FROM THE USE OF ZERO-POINT, TIMING AND UNDERSIZE PULL-STUDS? > These different types of pull-studs offset the spacing tolerances of
pull-studs and clamping modules. The fixed reference point is achieved through the zero-point pull-stud; the slit pull-stud serves to compensate for the still-free axis. The under size pull-stud does not have a centring function, but only a clamping and holding function.
CAN I INSERT THE PULL-STUD DIRECTLY INTO THE WORKPIECE FOR MACHINE PROCESSING?
> The high costs for chucking fixtures and workpiece clamping can be effectively saved if the pull-studs are mounted in the workpiece, which is clamped directly using the clamping modules. As a result, a complete 5-sided processing of the workpiece is possible in one chucking. With the different stud sizes (attaching thread M6 to M16), workpieces of different sizes can be clamped. HOW DOES THE SYSTEM COMPENSATE FOR HEAT, SUCH AS FROM METAL CUTTING? > Through the different pull-stud designs, the system can compensate for temperature differences between the workpiece and the clamping module easily and controllably. If you have other technical questions, please contact us at any time. WHAT SHOULD BE THE SPACING TOLERANCE OF THE PULL-STUDS AND THE CLAMPING MODULES IF SELF-PRODUCED? > The permissible spacing tolerance of pull-studs and clamping modules is +/- 0.01 mm.
