This manually operated hydraulic clamping system is characterized by a precise positioning of the clamping devices between the centers. This design enables precise assembly and exact workpiece position-ing – both for machining and for high-precision measuring tasks that require absolute run-out accuracy and repeatability.

It is operated by hand using a manual clamping screw. When the clamping screw is actuated, the oil in the closed system is compressed via a piston, causing the clamping area to expand evenly and cylin-drically within elastic range. In combination with permanently elastic clamping bushes and a closed clamping surface, this results in even workpiece clamping – ideal for bore centering.

The single taper clamping system from WILHELM KÖNIG MTM was specifically developed to meet the challenges of short clamping lengths, medium and large workpiece diameters, and varying toler-ances. It is characterized by its simple but effective mode of operation: the axial movement of the collet via the single taper generates a precise radial expansion of the clamping area. This not only reliably clamps the workpiece, but also centers and stabilizes it, pulling it down axially.

This principle enables secure clamping even with difficult work-

piece geometries, ensuring a reliable grip with maximum precision. Thanks to the quick and easy change of collets, the system shows its strengths particularly in automated processes or with frequently changing workpieces.

The thread clamping system from WILHELM KÖNIG MTM offers an efficient solution for the precise clamping of workpieces. The system consists of a screwed-on collet chuck mounted on a sturdy base mandrel. Thanks to a ground thread profile and an axial movement, the collet moves over the profile with high precision, resulting in a uniform cylindrical expansion – even with long clamping lengths.

Thanks to this technology, tolerances of up to IT 13 and beyond can securely be clamped, depending on the application and clamping diameter.

A special feature of our hydraulic quick-change system is the integrated pull-down of the clamping devices on the quick-change system. Manual actuation of the quick-change systems allows different clamping devices to be quickly and efficiently centered and clamped, resulting in a considerable reduction in set-up time.

By screwing in the manual clamping screw, the closed oil system is compressed by means of a piston and the clamping area is cylindrically expanded within its elastic range. This ensures maximum precision and secure fixing of the adapted clamping system.

The quick-change systems will be tailored to your machine connection and individually designed and manufactured.

The segment clamping system from WILHELM KÖNIG MTM is the ideal solution for clamping workpieces with compact to large clamping diameters. By using segment collets in different sizes, workpieces with varying clamping diameters can be clamped flexibly on a base. The expansion of the collets is precise and reliable thanks to the guided movement over the single taper.

A special feature of the collets is the material combination of high-quality tool steel and a high-tech elastomer. Depending on the size, the collets can expand by up to 1.2 mm while offering impressive durability and load capacity.
