Highlights

As a specialist for highly flexible solutions in hydraulic clamping and tensioning technology, we develop and manufacture customized solutions for a wide range of requirements.

The diagram shows examples of where KOSTYRKA products can be used. Whether as spindle, quill or tailstock clamping, for holding pallets or tables, the applications are many and varied.

Enclosed you can see a device with 2 centrically clamping mandrels.

The workpiece to be machined is picked up, centered and clamped during machining using these mandrels.

Device for processing a mirror blank for the European Extremely Large Telescope.

The mirror blank is aligned on this device and then ground to its convex aspherical shape with a thickness of only 100 mm and a mass of 3 tons during the approx. 1-year processing.

Kostyrka offers customized sizes from 6mm to over 2m diameter.

Kostyrka manufactures sleeves from a diameter of 6mm up to sleeves with a clamping diameter of more than 2m (example: use in peeling machines).

The shortest sleeve to date has a length of approx. 20mm, the longest sleeve measures 900mm.

Kostyrka's ability to manufacture sleeves in a wide range of sizes enables you to find the perfect solution for your individual requirements.

Accumulators in hydraulic systems: Reliability and safety despite power failure.

Accumulators are an important component of hydraulic systems and play a crucial role in maintaining the working pressure, even if the primary energy fails. The core of an accumulator is a gas pressure spring element that generates the hydraulic pressure through potential energy.

The advantage of an accumulator is that it ensures a constant holding force or holding torque in the KOSTYRKA clamping elements.

Various types of pressure generators can be used to discharge the accumulator. The KOSTYRKA oil-oil pressure generators or air-oil pressure generators can be used.
