The family-owned company SPREITZER PRÄZISIONSWERKZEUGE was founded in 1983 by Johann Spreitzer and since then has stood for the development, design and manufacture of complex system solutions in the fields of clamping technology and measuring technology.

Easy to handle – economical – modularly expandable


The ALUMESS clamping system is an extremely flexible and comprehensive modular system for fixing workpieces on measuring machines. The clamping system is based on a perforated plate on which the various clamping elements and clamping fixtures can be positioned. This perforated plate is screwed onto the measuring plate of the measuring machine.
The modular ALUMESS clamping systems enable the precise and reproducible setup of clamping devices. They are designed for flexible use at the measuring station, on coordinate measuring machines, on optical measuring devices and in computer tomographs (CT). Various starter sets are available for a quick introduction to the ALUMESS system family, which can be expanded as required. We would be happy to put together a customized kit for you. Modular concept Simple, fast and economical The ALUMESS clamping systems consist of many modular elements that can be assembled easily, quickly and economically to create reproducible clamping and fixing devices with precise positioning. Flexible The ALUMESS clamping systems offer the user maximum flexibility and enable part-specific or customer-specific clamping solutions in the measuring room. Stable The components of the different systems are bolted together directly, forming a stable, rigid connection. The space-saving design of all components ensures optimum accessibility to the measuring point.

ALUMESS.basic clamping device

Fixing and clamping of workpieces in just a few seconds thanks to the quick-change mechanism of ALUMESS.basic. The clamping system is suitable for tactile measurement at the measuring station or on coordinate measuring machines. The workpieces are fixed in the correct contour. The clamping system for metrology can be flexibly combined and is suitable for tactile measurement, individual measurement and can be used universally on coordinate measuring machines or at the measuring station. A detailed system description as well as various basic elements, clamping elements, support and positioning elements can be found in our ALUMESS clamping systems product catalog.

ALUMESS.junior clamping system

The ALUMESS.junior, the cost-effective entry-level clamping system for series measurement on tactile coordinate measuring machines. The assembly of the components is user-friendly and enables fast clamping of the workpieces to be processed. ALUMESS.junior is suitable for pallet automation. Various support and positioning elements as well as the necessary clamping elements can be quickly positioned and mounted on the pallets equipped with clamping threads. The assembly options for the components are designed to be logical and user-friendly. The clamping system can be palletized. A detailed description of this clamping device and a wide range of accessories can be found in the ALUMESS clamping systems product catalog.

ALUMESS.maxx clamping system

Stable clamping device with a wide range of components. Suitable for series measurement on tactile coordinate measuring machines. ALUMESS.maxx can also be used for sample or prototype construction, for laser marking and laser processing and as an assembly device. The clamping system is suitable for pallet automation. The pallets, plates, angles and strips have continuous positioning holes and fastening threads. A comprehensive range of positioner, stop and support elements enables a reproducible, stable and precise positioning of the clamping device. Thanks to the maximum reproducibility of the devices, only part-specific elements need to be stored for later reuse. In our ALUMESS clamping systems product catalog you will find a large selection of basic elements, support and positioning elements, clamping elements and accessories.

ALUMESS.easyloc clamping system


ALUMESS.easyloc clamping systems consist of modularly combinable and easy-to-install, magnetically interlocking interchangeable pallets. The fixture solutions can be changed quickly. The modular fixture pallets and clamping elements help to produce perfect parts faster, easier and cheaper than ever before. Alumess.easyloc speeds up and simplifies the measuring process with modular, magnetically interlocking quick-change clamping solutions. Existing devices can be easily retrofitted.

Elements from ALUMESS.junior and ALUMESS.maxx can be used.

ALUMESS.optic clamping device


This flexible clamping system is designed for individual and series measurements on optical coordinate measuring machines and measuring projectors. The ALUMESS.optic clamping device can be used on multi-sensor machines for tactile measurement and for incident and transmitted light. The clamping device can be palletized. The guide grooves in the base rails and connecting rails allow the tenter frames to be moved continuously and scalably. A detailed system description of the clamping system as well as clamping elements, support elements and positioning elements can be found in our ALUMESS clamping systems product catalog.

ALUMESS.xray clamping device


ALUMESS.xray the clamping system for computed tomography (CT) measuring devices. Easy to install, can be flexibly combined, X-ray transparent, suitable for individual and series measurements.

Elements from ALUMESS.basic, ALUMESS.junior and ALUMESS.easyloc can be used.
