By using modern VEKTEK zero-point systems, you optimize fixture and workpiece changeover in your production, correspondingly reduce set-up times on the machine and so save money! The benefits of zero-point clamping technology are obvious:
The pull-stud in our zero-point system is the interface between the machine table and the workpiece or fixture. It ensures exact positioning and secure clamping. The resulting work forces are transferred through the pull-stud to the clamping module.
The precisely manufactured clamping modules of the VEKTEK Zero-Point System ensure a secure and firm hold of the workpiece or fixture to be clamped. With the high pull-in, closing and holding forces, they are suitable for every application.
Experience a zero point clamping system that, through its innovative and forward-looking features, presents its strengths in use in an advanced way.
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 Repeatablility?
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.

Classic Pull-stud Arrangement
This arrangement of the clamping modules always optimally positions the pallet to be changed. At the same time, the zero-point pull-stud always represents the reference point. The timing pull-stud serves to compensate for the free axis. The undersize pull-stud has only a clamping and holding function
Optional Pull-stud Arrangement
The exclusive use of timing pull-studs compensates for stronger temperature influences. The reference point always remains in the center of the pallet. Of course, temperature influences from machine processing can generally be ignored since the heat generated is conducted away by the chips and coolant.
