What is the CNC punch machine?

Punching and creating holes or protrusions in all kinds of existing materials, including metal sheets, paper and wood, can be considered as the general definition of punch. Sheet punching with a CNC machine or punched sheet (perforated metal) is also a metal forming process in which, using a punch press, force is introduced into a tool called a punch to insert into the metal piece and create a hole in it by cutting the piece. The raw materials used to make the punched sheet may be galvanized sheet (white), oil sheet (cold rolled), black sheet (hot rolled), aluminum sheet or steel sheet. Also, the punched sheet is produced and supplied in various thicknesses, and each of its types has a specific application.

Often, after passing through the piece and piercing it, the punch is inserted into a welded hole under the piece. The holes created in the panj sheet may be circular or rectangular, but sometimes there is a need for holes with more complex shapes. To make these shapes, the sheet is passed under the machine several times with accurate calculation of the position, or multiple punches are used. Depending on the type and material of the part being punched, these scrap parts may be recycled and reused or discarded.

CNC Sheet Punch Machine

Sheet punching with a CNC machine is a manufacturing process that is carried out by a CNC press. This design machine has several tools and by using new technologies, it allows us to move a metal sheet in the direction of the x and y axes so that the sheet is carefully placed under the machine's punch ram and is prepared for punching, and finally it is punched in the exact place. As a result of this movement, in addition to high production speed, all kinds of hole shapes can be executed on metal sheets (special geometric shapes, shapes required for making industrial parts or decorative shapes). The CNC punching machine takes command from the computer to perform the punching operation, so it has very high accuracy and low error rate. The CNC punching machine can punch different metal sheets such as steel sheets, galvanized sheets, aluminum sheets, iron, steel, brass, bronze, galvanized and other metal sheets.

To create complex shapes from the metal sheet, a combination of overlapping multiple punches and separate blows is used. This machine also creates 3D shapes and sheets such as bends, recesses, twists and half cuts in sheets of different capacities. These shapes are often used in the design of metal enclosures. This device has the ability to create a spiral rib, fold small strips, punch the cut edges without creating any tool marks, and as a result, they are very productive devices.

What is the performance of the punch machine?

Metal sheet punching by a CNC punching machine is a manufacturing process that is performed by a ram punch press on the sheet. For cutting, we will first design the plan by AutoCad or CAM software and then give it to the machine. In order to apply punches on metals, supports or arms of the machine, move the metal sheet accurately in the X and Y directions so that the point intended for the punch or hole is located exactly under the part called the punch in the CNC punching machine. The punching machine presses the metal sheet with very high power and pierces it, and separates the extra piece of metal from the metal sheet so that the metal sheet receives the corresponding shape in the CNC program. It should be noted that the operation is carried out under the supervision of the operator. This operation can also be done in another way by a metal laser cutting machine. The shapes that can be punched by this machine can be simple geometric shapes such as circle, square, rhombus, etc. The iron sheet punching machine will be able to create shapes with higher complexity than geometric shapes and will do this by successive punches.
