Hydraulic clamping technology from Gerlingen near Stuttgart

KOSTYRKA GmbH develops and manufactures hydraulically actuated clamping elements: clamping sleeves and expansion sleeves with and without flange, clamping discs, clamping rings, clamping strips and clamping cassettes as well as support elements, pressure generators and adaptive clamping and fixture systems. The core of each sleeve is a flexible base body made of metal-plastic composite; as a rule the sleeves are made of bronze, or of steel for spindle clamping at high speeds. Clamping sleeves are manufactured with inner diameters from 6 to over 2,000 mm and lengths up to over 900 mm for operating pressures up to 600 bar. The clamping elements hold shafts, spindles, rotary tables, pallets and other machine elements firmly without reaction force and release them in a flash. Support elements stabilize workpieces with support pins from 10 to 40 mm in diameter and forces up to 28 kN. Customers include manufacturers of machine tools, fixture and assembly systems as well as companies from the optics, aviation and aerospace sectors. Development and manufacturing take place exclusively at the Gerlingen site near Stuttgart.

Quality assurance

All important geometric features of the clamping elements are inspected using a 3D coordinate measuring machine (stationary and mobile, also directly on the machine) and documented in measurement reports. In addition, microscopic inspection for burrs and chips, casting density and leak tests, laser measurement methods and functional tests are performed; every product is marked with a product, order and count number.
