Clamping systems

Quality is the word when it comes to selecting interfaces between machine and tool. Quality in regards to construction, tool steel and manufacturing quality, but also quality in protecting tools and machines and delivering the required machining results. High process reliability, perfect concentricity, high axial run-out accuracy, high balancing quality and maximum clamping force are just a few of the requirements that modern clamping devices and clamping systems must meet today. With the wide variety of clamping solutions offered today, the choice for customers can sometimes be overwhelming.

With its long experience in the machining of wood, wood-derived materials, plastics and NF-metals, Leitz offers a range of clamping devices that is perfectly matched to the type of machining, machine types and materials.

Clamping systems for stationary machines

To be able to use tools on stationary machines and machining centers, chucks and clamping arbors with the appropriate spindle interface are required. These adaptations create the connection to the spindles that transmit the rotational movement to the system.

Leitz offers a range of shrink chucks, collet chucks, special drill chucks or clamping arbors for these machine and aggregate types, which perfectly transfers the performance of the machine to the tool and thus form a closed machining system.

High-performance chucks

In high-performance machining, perfect cutting quality on the workpiece and maximum tool life on the tool are of the utmost importance. Leitz offers the ideal solution with its ThermoGrip range of shrink chucks. The thermal clamping of the shank tool offers maximum process reliability and the high balancing quality of the entire clamping system protects the spindle and machine.

Collet chucks

The collet chucks in the Leitz tool range offer maximum flexibility thanks to fast tool change and exceptionally high concentric accuracy.

Drill chucks and quick-change drill adaptors

Leitz offers a wide range of drill chucks for the process-reliable mounting of boring tools on the main spindles of CNC processing machines. Leitz has developed special quick-change drill adaptors for fast and safe tool changes. Easy to use, easy to handle and producing perfect boring results every time, our special quick-change drill adaptors have to be seen to be believed.

Clamping arbors

The safe adaptation of single and set tools with bore on CNC machining centres or through-feed machines is recommended through clamping arbors. Leitz offers an extensive range with common HSK adaptors for automatic or manual tool change.

Clamping systems for through-feed machines

In order to be able to use tools on through-feed machines, clamping systems are required that adapt to the spindle shape or to a corresponding transmission shaft.

Leitz offers a comprehensive and well-selected product range of clamping sleeves, quick-clamping elements and hydraulic clamping systems, which guarantee the transmission of power to the tool.

Hydro clamping – open systems

Hydraulic clamping systems, in the form of an open system with grease gun application, are mainly used for the flexible tool clamping of individual tools or tool sets on machines and systems for solid wood processing.

Hydro clamping – closed systems

Hydraulic clamping systems, in the form of a closed system with key application, are often used on machines and systems such as double end tenoners and floor production.

Clamping sleeves

The conventional interface between boring tool and machine spindle is the clamping sleeve. It is mainly used to mount individual tools together in sets or as a flange sleeve for mounting hoggers or scoring and grooving sawblades.

Quick clamping elements

Hydro quick-clamping elements are mounted centrically on high precision spindles. Equipped with a hexagonal locking device for fast and precise tool change or boring tools and hoggers, this adaptor is often used on double-end tenoners and edge processing machines.

Quick-clamping elements, which are mounted on standard spindles with keyways, are mainly be used on furniture machines. They ideal for fast clamping and changing of hoggers and cutting tools.

Clamping arbors

The safe adaptation of single and set tools with bore on CNC machining centres or through-feed machines is recommended through clamping arbors. Leitz offers an extensive range of standard HSK adaptors for automatic or manual tool change.
