The working medium of the 80-ton servo single-arm press not only transmits pressure but also ensures the machinery's working parts operate sensitively, reliably, with a long service life, and minimal leakage.

The basic requirements for the working medium of an 80-ton four-column guide single-column hydraulic press are:
① Features suitable liquidity and low compressibility to enhance transmission efficiency.
② Rust-resistant
③Excellent lubricating properties;
④ Easy to seal
⑤ Stable performance, maintains quality during long-term operation. This series of presses utilizes steel plate welding structure, ensuring high strength, stable precision, and long-lasting durability. The machine is equipped with a hydraulic overload protection device. It optimizes the use of three-dimensional space, expanding the working range and can be customized according to customer requirements.
