History Of Cnc Punch

In modern sheet metal processing plants, CNC punches have long been one of the most widely used equipment. But do you know where the cnc turret punching machine first came from? this article will give you a brief analysis of the change history of cnc punching machines.

As early as 1971, with the evolution of computer technology from integrated circuit computers to large-scale integrated circuits, Amada took the lead in applying it to stamping equipment, and the world's first CNC punch LYLA-555 was born.

Through a variety of die punching methods at different positions of the sheet, the situation of having to design and manufacture a die for a single part was improved in one fell swoop, and a new field of sheet metal processing was opened.

The No. 1 machine at that time already had the necessary elements of modern CNC punches such as turret die change and bridge type racks. Once launched in the United States, it quickly occupied the market and exported to the European countries such as Britain and Germany . In order to better serve local customers, AMADA has also established branches in various countries, which also contributed to its becoming a global multinational enterprise.

CNC punch press, full name is Computer Numerical Control Turret Punch Press. AMADA took the first letter of each word and became CNCTP, then simplified to NCT and registered it as a registered trademark.

Therefore, until now, only AMADA CNC punches can be called NCT.

And what really makes CNC punches a household device must be attributed to the evergreen tree of the NCT: the PEGA series. The PEGA series NCT was born in 1987. With a higher punching rate and more stable quality, it has become the hottest product in the entire sheet metal processing industry. With the introduction of the PEGA machine, AMADA has also reformed the painting of the equipment. Red and black with red as the main color and black as the main color are still widely used until now.

It is worth noting that the first CNC punches of AMADA were almost named after the constellations in the sky. Such as COMA, ARIES, etc., fully reflects the romanticism of sheet metal processing and its diverse products at the time with the rapid development of the global economy.

In 1988, with the customer's requirements of "hope for higher punching rate" and "hope for higher precision forming processing", AMADA successfully developed the second generation CNC punch series VIPROS.

The biggest difference between the VIPROS series and the previous CNC punches lies in their driving methods. The conventional mechanical drive method was changed to a hydraulic drive.

The advantage of hydraulic drive is that because the top dead center position of the punch can be arbitrarily controlled, the stroke of the punch can be shortened, and the punching speed can be increased. At the same time, when the hammer is at the bottom dead center position, the hydraulic drive can provide the holding time required for processing, so that the stamped metal can be plastically deformed, thereby obtaining a non-rebounded, more accurate formed workpiece Already.

On the other hand, in order to match the different standard sizes of raw material manufacturers, the VIPROS series provides different table options. Today's 4 × 8-foot countertops, or 1250mm × 5000mm large countertop standards, were established in the VIPROS era. Considering the back scratch of the board and the collision between the board and the turret, VIPROS took the lead in adopting a new work table with a combination of liftable universal rollers and high-density brushes, creating the first to protect customer products. Equipment manufacturing concept.

With the increasingly fierce competition in the sheet metal processing industry, in order to help users further save production costs, AMADA launched the third-generation CNC punch EM series in 2002.

The advent of the EM series unveiled the era of cnc punching machines driven by servo motors.

The servo-motor-driven EM, while retaining all the advantages of VIPROS, drastically reduces production power consumption and maintenance costs, and finally makes the CNC punch press evolve into the best form. The dual-servo motor direct-drive EM, with the highest punching rate, the lowest maintenance cost, and the best processing quality in the industry, has become the processing equipment that customers can't rely on until now. Since then, all NCTs developed by AMADA are based on EM and developed with EM as the origin. These include the popular AC and AE series, the EM-MⅡ series with more abundant processing methods, and the EMZR series that achieve the highest processing quality.

King of CNC punches The latest evolution of EM series: EM-MⅡ series

It can be said that the road of AMADA CNC punching is the road of sheet metal processing development and change. On AMADA CNC presses, there are countless high-quality products being produced all over the world. This punching path will always be heard throughout the sheet metal factory and never stop.
