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.
The repeatability specifies the tolerance range within which the recorded reference points on the workpiece lie after removal and re-clamping of the same workpiece. The repeatability, also called repetition accuracy, is below 0.005mm.
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 timing pull-stud serves to compensate for the remaining free axis. The under-size pull-stud does not have a locating function, but only a clamping and holding function.
The high costs for chucking fixtures and workpiece clamping can be effectively saved here 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.
The permissible spacing tolerance of pull-studs and clamping modules is +/- 0.01 mm.

Especially when injection molds are changed frequently, the costs for a zero-point solution are amortized within the shortest of times for such machines. Unlike with mechanical clamps, clamping takes place quickly and easily just by pressing a button.
The maximum processing temperature is 80°C in the standard design. Clamping modules for use at higher temperatures can be requested at any time.
Blow-out using compressed air is guided through the floor of the clamping module and blows out contamination, such as chips or coolant.
If the piston seal begins to leak, the spring space quickly fills with oil. The result is: The piston blocks and the module can no longer be opened. Destruction of the clamped fixture of the of clamping module would then be unavoidable. Here, the safety system ensures that the oil in the spring space can escape and the piston can be operated.
