What is punching?

Punching is the process of forming metal components using a punch and matching die. The punch is usually the upper member of the complete die assembly and is mounted on the slide or in a die set for alignment (except in the inverted die). In the case of the hydraulic ironworker, the punch is forced through the material by the hydraulic ram with forces from 40Ton up to 180Ton. The clearance of the punch to die is calculated for each material thickness range to give optimum results. During the first stage of punching, the material is compressed before going past the point of elastic deformation, upon which the shear occurs.

What is notching?

Notching is a metalworking operation in which the punch removes material from the edge or corner of a strip or blank or part.

What is shearing?

Shearing is a cutting force applied perpendicular to material causing the material to yield and break. Shearing is a process for cutting sheet metal to size out of a larger stock such as roll stock. Shears are used as the preliminary step in preparing stock for stamping processes, or smaller blanks for CNC presses.

What is the difference between SweBend 3 and 4 roll machines?

Generally, 3 roll machines are better suited for bending companies that perform many unique bending operations and require high versatility. 3 Roll machines are mostly delivered with manual controls and depend totally on the experience and skill of the operator.

4 roll machines are better suited for repetitive series production and are almost always equipped with SweBend’s powerful CNC to create Precise Bends time after time with the highest precision. Many 4 roll machines used for production of lighter parts are integrated into robot loaded cells with automatic load and offload. A shorter straight end on the leading edge is available with 4 roll systems.
