ECONOMICAL, PRECISE, QUICK - THE VEKTEK ZERO-POINT SYSTEM
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: > Increase in machine run-time > Very fast workpiece or fixture changeover > High repeatability > A uniform interface for all machines > Positioning and clamping in a single step

> 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.

LARGE INTAKE CATCHMENT
SWING-FREE Swing-free run-in and run out through the optimal contour of the pull-stud.
FORM FIT The balls are optimally encapsulated on 3 sides. As a result, the pull-stud always remains firmly clamped in the module.
No laborious searching for the holes anymore - self-centring via the diagonal side surfaces of the engagement screw.
YOUR ADVANTAGES - THOUGHT THROUGH IN DETAIL Experience a zero point clamping system that, through its innovative and forward-looking features, presents its strengths in use in an advanced way. Numerous advantages speak for themselves and make the VEKTEK zero-point system into a technology that revolutionizes the zero-point clamping technology market.
SIMPLE CLEANING Our zero-point clamping sytems can be blown out very simply with a commercially available compressed air cleaning pistol and do not require complicated suctioning out.
BLOW OUT Our system has a pneumatic blow-out installed at the factory. As a result, chips and dirt inside are effectively blown out.
RUSTPROOF STAINLESS STEEL High-alloy, hardened tool steel - so no corrosion.

THREE-POINT PRINCIPLE
MEDIA FEED Due to the lateral media feed, low pallet thicknesses are possible and fewer feed holes are necessary.
NO BALL CAGE The balls lie freely in the ball canal. This freedom of movement enables the balls to continuously re-position themselves.
Power transmission by means of the three-point principle! This optimised force distribution prevents shearing load on the balls.
LARGE BALL DIAMETER Ball surface is 784% greater than with traditional ball systems.
SAFETY SYSTEM Process reliability - Clamping module always opens. A piston blockade is thus impossible.
GOOD HOLDING, PULL-IN AND LOCKING FORCES Holding force of up to 105 kN*. Pull-in and locking force of up to 40 kN.

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.

AUTOMATION SOLUTIONS FROM VEKTEK
The enormous capability and flexibility of use of modern processing machines is undisputed. To be able to use these capabilities in reality requires more than just fast machines. An automation solution today includes a variety of interconnected, versatile products and technologies. Through the possibility of a fully automatic and process-sure machine configuration, our automation solutions meet the requirements for seamless integration into the automation system. Numerous sensing options, optional coupling elements and blow-out and blow-off of the modules speak for themselves! Please consider utilizing the automation potential of the VEKTEK zero-point clamping modules!
IS THE MODULE OPEN? Through the direct monitoring of the piston position (opened) by means of pneumatic back pressure, the position can be sensed by means of a differential pressure switch.
5. LOCKING CONTROL
IS THE MODULE LOCKED? With an open module, the integrated stop valve creates a pneumatic static pressure, which is sensed via a differential pressure switch.

4. STUD SENSING
IS THE PULL-STUD PRESENT ON THE FIXTURE? The retracting stud activates a stop valve, which helps to eliminate pneumatic or hydraulic static pressure. This condition is detected by a differential pressure switch.
DIRT AND CHIPS IN THE CLAMPING MODULE?
DIRT AND CHIPS UNWELCOME IN THE MODULE? The central lock prevents dirt and chips from entering when the pull-stud is being run out. It replaces the previously required protection pull-stud.
Using compressed air for cleaning removes dirt and debris from the inside while also providing workpiece support control through a differential pressure sensor.
6. COUPLING ELEMENTS
7. BLOW-OFF/SUPPORT CONTROL
IS A WORKPIECE LYING WITHOUT GAP OR NOT? The blow-out function with compressed air cleans the support surfaces and can also be used for workpiece support control through a differential pressure sensor.
ARE COUPLING ELEMENTS TO A FIXTURE NECESSARY? Oil and compressed air can be run through our couplings without leaks.

Pull-stud arrangement
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.

Timing pull-stud Zero-point pull-stud Undersize pull-stud
OPTIONAL PULL-STUD ARRANGEMENT The exclusive use of timing pull-studs compensates for stronger temperature influences. The reference point always remains in the centre 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.
