What is the difference between hydraulic shears and mechanical shears?

Hydraulic shearing machine uses hydraulic system to apply pressure to make the blade move to shear. It has large shearing force, can shear a wide range of plate thickness, can adapt to thicker plates, and has a smooth shearing process, low noise, and high precision. However, its price is relatively high and its maintenance cost is also high. Mechanical shearing machine relies on mechanical transmission device to drive the blade to move. It has simple structure, low cost and convenient maintenance. However, its shearing force is relatively small and it is suitable for thinner plates and occasions with low precision requirements.
