Secondly, the low energy consumption and stability of fiber optic oscillators allow sheet metal processing companies to conserve energy and reduce production costs.

The elimination of the need for large quantities of cooling water and power supply contributes to more environmentally friendly production practices. Additionally, fiber optic oscillators offer longer service life and lower maintenance costs, enabling sheet metal processing companies to sustain high-efficiency production over extended periods of time.


Evolution of press brake drive mode

Mechanical drive to hydraulic drive to hybrid drive mode

The evolution of the drive mode of the press brake: from mechanical drive to hydraulic drive to oil-electric hybrid drive mode press brake as an important metal processing equipment, the evolution of its drive mode witnessed the development of China's metal processing technology and innovation.
