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.
