CKV
The CKV forging press is a push‑down four‑column hydraulic press designed for open‑die forging of heavy components. CKV presses by ŽĎAS provide forming forces from approximately 630 to 14,000 tonnes and are used for forging ingots, shafts, blocks, rings and complex steel forgings. Robust design and optional automation make them suitable for demanding heavy‑duty forging operations.
CKV forging press – push‑down hydraulic press for open‑die forging
CKV forging presses are push‑down four‑column hydraulic forging presses designed for open‑die forging of heavy forged components. These presses are developed and manufactured by ŽĎAS, a.s., one of the leading European suppliers of equipment for heavy forming, forging and metallurgical applications.
The CKV press series covers a wide range of machine sizes with nominal forming forces from approximately 6.3 MN up to 140 MN, corresponding to about 630 to 14,000 tonnes. CKV presses are intended for open‑die forging of ingots, shafts, blocks, rings, discs and complex shaped forgings made of carbon, alloyed and high‑alloy steels.
Design and operating principle of CKV forging presses
CKV forging presses feature a four‑column frame structure with a hydraulic push‑down forming action. This design ensures high frame rigidity, uniform force distribution and stable machine behaviour even under extreme forming loads. Depending on the configuration, the press can operate in manual, semi‑automatic or fully automatic modes, allowing adaptation to different production requirements.
CKV presses can be supplied as stand‑alone machines or as part of a complete integrated forging unit, including rail‑bound forging manipulators, rotary tables, ingot carriages and auxiliary equipment. Such integrated solutions significantly increase productivity, process safety and repeatability in heavy forging operations.
Automation and process control
CKV forging presses may be equipped with ŽĎAS TechForge automation software, which enables automated control of the forging process based on predefined technological recipes. This system provides:
- automated control of forging cycles,
- reduced overall forging time,
- lower electrical energy consumption,
- minimisation of operator influence on forging quality,
- improved process repeatability and consistency.
This level of automation makes CKV presses suitable for modern forging shops where high productivity and stable quality are essential.
Applications of CKV forging presses
CKV forging presses are typically used in:
- heavy forging shops and metallurgical plants,
- production of large open‑die forgings,
- heavy mechanical engineering,
- energy industry, including power generation and nuclear applications,
- manufacture of shafts, rotors, pressure components, rings and large structural parts.
Forged components produced on CKV presses may weigh from several tonnes up to tens of tonnes, depending on press size and configuration.
