There are two types: hydraulic angle cutting machine and pneumatic type angle cutting machine and it's used for notching or cutting right angle on sheet metal, this angle shearing machine has a steel welded structure which confirms enough stiffness and physical strength. Adopt hydraulic drive. Can adjust the angle between 40°-130°, and this machine has a small size, lightweight, and a novel structure. It is suitable to process metal plate with a fast and accurate processing and the notching quality is good. This two kind of angle shearing machine is very different, the pneumatic type maximum thickness is 1.2mm, but the hydraulic angle shearing machine maximum thickness is 3mm, and the weight also different, hydraulic angle shearing machine is 200kg, but pneumatic angle shearing machine just 70kg.
