Clamping and Positioning Systems
Clamping and Positioning Systems for Highest Precision and Process Forces
The functional principle of the reference chuck is that it is adapted to the process forces that occur. The clamping elements (whether balls, rollers, segments or screws) are chosen to execute the optimal transmission of clamping and process forces.
PPS Clamping System | Reference Clamping System for Tools and Fixtures
PPS
Highest precision and clamping force
Positioning accuracy of +/- 0,001 mm combined with maximum clamping forces up to 70 000 N.
Modular design
Adaptation to tool geometry and different process forces.
Size graduation
Staggered sizes cover the tooling and pressing requirements.
Functionality
The chuck is opened by compressed air, the pallet is placed on top and the pallet is clamped by a spring-based clamping mechanism by depressurizing the chuck. To unclamp the pallet, the chuck must be opened by applying pressure.
The chucks can be operated with different pallet shapes. The pallet is inserted manually or automatically with a repeatable positioning accuracy of +/- 0,001 mm.

Innovative roller clamping system
The patented roller clamping system with multi-shaped clamping rollers enables the highest clamping forces in the smallest installation space. Compared to clamping with balls, four times higher clamping forces are achieved. At the same time, significantly higher pull-out forces can be absorbed.
Basic principle of PPS chuck
Types of PPS reference clamping system
- Pneumatic clamping system PPS centered or positioned with positioning system Prisma Power S supports a wide range of applications.
- Different base plates enable connection to the press or machine tool.
PPS ceramics reference clamping system for ECM application
Electrochemical Machining (ECM) prefers clamping systems with inert behavior towards current and electrolytes.
Reference clamping systems made of ceramic are an optimal solution for this.
PPS reference clamping system with SCS K positioning system with any basic shape
PPS reference clamping systems can be fixed in base plates of any number and position.
PPS reference clamping system PPS SQR 545 x 165 mm
Pneumatic rectangular reference clamping system with 6-fold arrangement PPS 60-C chuck with SCS K positioning system. Dimensions 545 x 165 mm. Clamping force 96 kN (power clamped).
PPS reference clamping system PPS 480 S with diameter 595 mm made of carbon fiber
Pneumatic round reference clamping system with 3-way arrangement PPS 60-C chuck with centering system. Pallet outer diameter D 595 mm and a clamping force of 22.5 kN.
For weight reasons, the clamping system is partially made of carbon fiber and the pallet is made entirely of carbon fiber.
