What is Numerical control press？

Numerical control press is a highly automated sheet metal processing equipment in modern industry, whose core lies in accurately controlling the punching action through a digital control system to achieve efficient and precise processing of sheet metal. Compared with traditional punching machines, Numerical control press combine computer programming, servo drive, and multi station mold technology, which can automatically complete complex hole patterns, irregular shapes, and shallow stretching processes. They are widely used in metal sheet processing in fields such as electronics, automobiless, and home appliances.

1. Definition: Automated stamping equipment controlled by programs

Numerical control punch press is an automated machine tool equipped with a program control system, whose core lies in precise control of punch press movement through a numerical control system (CNC). Unlike traditional punching machines that rely on manual operation, Numerical control press can automatically complete the entire process of sheet positioning, mold switching, stamping actions, etc. according to pre programmed processing programs, achieving "one-time clamping and multi process processing". For example, in the processing of server cabinet side panels, Numerical control press can complete the stamping and forming of hundreds of installation holes, ventilation holes, and reinforcement ribs at once, with an efficiency improvement of 3-5 times compared to traditional processes.

2. Working principle: Collaboration between multi axis linkage and mold turret

The working principle of Numerical control press is based on the technology of "multi axis linkage+mold turret":
(1) Motion axis control: The precise movement of the sheet metal is driven by X/Y axis servo motors, which are combined with the A axis (mold rotation) and C axis (mold indexing) to achieve complex hole processing. For example, when processing large circular holes using the step punching method, the small die can continuously punch along the curved trajectory to form a smooth contour.
(2) Mold turret system: Multiple sets of molds (usually 8-32 workstations) are installed on the turret, and the CNC system automatically rotates the turret according to program instructions, quickly switching between molds of different shapes or sizes without the need for manual mold replacement.

(3) Stamping mechanism: The main motor drives the flywheel, clutch, crankshaft and other components, converting circular motion into linear motion of the slider, and applying pressure to the sheet metal to complete stamping.

3. Core advantage: Triple improvement of efficiency, accuracy, and flexibility

Compared to traditional punching machines, Numerical control press have significant advantages:
(1) High processing accuracy: The repeated positioning accuracy can reach ± 0.1mm, ensuring the consistency of batch product dimensions.
(2) High production efficiency: The single minute flushing can reach 300-600 times, and it can run continuously for 24 hours.
(3) Strong flexibility: Different products can be processed by simply modifying the program, adapting to the production needs of small batches and multiple varieties.

(4) Cost optimization: By using processes such as step punching and continuous punching, we can reduce mold investment and lower individual unit costs.

4. Application field: Cross industry metal sheet processing tool

The application of Numerical control press covers multiple industries:
(1) Sheet metal processing: standard configuration for producing electrical control boxes, network cabinets, and other products.
(2) Elevator industry: punching and forming of components such as car wall panels and floor doors.
(3) Home appliance manufacturing: stamping the heat dissipation holes and strengthening structures of refrigerators and washing machine shells.
(4) Automotive components: Production of complex shaped parts such as door inner panels and engine mounts.
(5) Architectural decoration: Processing decorative components such as metal ceiling panels and ventilation louvers.
As the core equipment of modern sheet metal processing, Numerical control press achieve efficient automation processing from simple hole patterns to complex irregular shapes through the coordination of program control systems and high-precision transmission mechanisms. Its core advantages lie in high processing accuracy, large format, strong flexibility, and the ability to quickly switch molds to meet the production needs of multiple varieties and small batches. With the integration of servo drive technology, intelligent sensing, and IoT technology, Numerical control press are evolving from single processing equipment to intelligent manufacturing units, providing more efficient and reliable sheet metal solutions for fields such as aerospace, automotive manufacturing, and electronics, becoming one of the key equipment driving the transformation of Industry 4.0.
