CNC Punch Press

CNC punching is a sheet metal fabrication process done by (cnc) computer-controlled punch press machines. In CNC punching, presses use distinct rams to make holes or indent forms into sheet metal. Design details are fed into the punching machine directly from CAD/CAM design software which computes the most optimised layout to maximise sheet utilisation and select the correct tooling to create the desired components. When ready and in position, the punch presses will punch a hole or form into the material. The scrap is forced through, leaving the required hole or aperture in the metal. 

Cnc punching has hit ability up to 1000 ‘hits’ per minute and thus is a high-speed system of manufacturing metal components. CNC punching is a non-thermal process so it does not create any Heat Affected Zone (HAZ) in the material. By this method, we can produce flat components, 3D forms in the material, such as dimples, louvres, embossed logos and hooks. Also tapping and countersinking can be shaped in situ, removing the need for ‘secondary operations. The CNC punching’s speed and efficiency when manufacturing components with complex 3D perforated shapes is unrivalled. Cluster tool systems are utilised to lessen the set-up and tool changing time, improving the cost efficiency of the whole metal punching process.

Precision machines with state-of-the-art servo-electric punching technology. Highly accurate CNC punch presses can form superior grade repeatable, quality profiled flat pattern blanks to almost any shape accurately and repetitively.

A CNC punch press machine is an automated production machine utilised to form or punch out pre-determined shapes from thin stock material. A CNC punch press machine is utilised for cutting holes, forms, bonds, or shaping material. They have a CNC system and are controlled and operated by machinists. A CNC punch press machine can effortlessly stamp shapes into metal pieces. CNC stands for Computer Numerical Control and denotes the computer programs which control the machine's operational cycles. They have ability to create cleanly edged shapes on a wide range and thickness of materials, CNC punch presses are central to the modern sheet metal fabrication industry. CNC Punch Press has great flexibility and the efficient processing of sheet metal as it has the ability to position the metal sheet under the punching head with high precision accuracy.

CNC punch presses are turret-type machines comprises of three standard assemblies: a main work bed which moves two dimensionally, a powered press turret and a set of controls that contain the computer station. The procedure of punching material comprises a workpiece normally a thin metal sheet, being moved into position under the press die along an X- and Y-axis by the computer program. When the work piece is in place, the program instructs the die to move down and form or cut out the wanted shape, and then back up to repeat the cycle.

• Good rigidity and total elimination of welding stress guarantees long-term accuracy.

The advantages of CNC punching are numerous and include:

• High speed and flexibility in working
• Lower running costs than Laser machines
• Coated material such as pre-painted sheet, galvanized steel
• Speeds of 1000 hits per minute can be attained. 
• No heat-affected zones (HAZ) that need to be revisited.
• Use of special tooling such as upforms, knock outs, countersinking, ribbing and thread forming
• Allows for tapping and countersinking which can be produced in situ, removing the need for secondary options.
• Able to produce 3D forms in the parent sheet metal such as CNC punched louvres, dimples, embossed logos and hooks.

CNC Punch pressing is perfect for heavy parts than those that can be created using four slide machines, parts that require punch pressing also typically need extra tonnage to form but also can be more complex and can use customized dies to help shape the cut hole to precision. Punch pressed parts normally find applications in consumer appliances, electrical outlets, outdoor power equipment, electrical, and fluid pumping products. 

A CNC punch press can be used to create holes, bonds, forms, or shapes material in a metal sheet of numerous shapes and sizes to make parts and components for several goods used in many industries. Examples of these include the aerospace, automotive, electronics, agriculture, and architecture sectors.
