A More Efficient Approach to Integrated Punching and Shearing，Derateck SAP3 1550 Punching & Shearing Compound Machine

Bringing Punching and Shearing Back to True Efficiency

In actual production, sheet metal punching, forming, and shearing are often divided into multiple independent processes. Punching is completed on a press, while cutting is handled by a separate shearing machine. Frequent transfers between different machines not only increase labor involvement and logistics costs, but also introduce cumulative positioning errors due to repeated setups, becoming a key factor limiting production efficiency and processing consistency.

Derateck SAP3 1550 punching and shearing compound machine was developed precisely in response to these real-world production conditions. By integrating a CNC turret punch and a CNC right-angle shear onto a single platform and sharing one CNC control system and feeding system, the machine enables punching, forming, and shearing to be completed continuously with a single clamping and a single positioning. This significantly shortens the overall process flow, greatly reduces material handling and repeated positioning, and lays a solid foundation for improving overall productivity and machining stability.

At the automation level, the SAP3 1550 is equipped with a sorting and discharge system that automatically classifies and outputs finished parts after processing. This reduces manual intervention and allows the machine to better adapt to continuous production rhythms. This integrated “processing + sorting” approach is particularly well suited for sheet metal applications with high demands on efficiency and takt time.

Detail-Oriented Design Serving Real Production Needs

In terms of punching and forming capability, the machine is equipped with two auto-indexing units. Multiple stations can be flexibly combined to complete punching and forming operations in various shapes, making the system well suited for multi-variety and batch production requirements.

The shearing unit features two independently mounted blade slides, each directly driven by a ball screw. This design ensures high shearing speed while effectively reducing energy consumption. The main drive system consists of a servo motor, synchronous belt, and ball screw in a direct-drive configuration, resulting in a simplified transmission chain, high reliability, and low routine maintenance requirements—helping to reduce total lifecycle costs.

From a control perspective, the blade stroke is fully programmable and can be flexibly set according to different processing tasks. This avoids unnecessary idle strokes and improves shearing efficiency. Operators only need to input the sheet thickness on the control panel, and the blade clearance is automatically adjusted, reducing manual adjustment errors while further enhancing ease of use and operational stability.

In addition, both blades support half-shearing functions, allowing the cutting length to remain unrestricted. Combined with the sheet re-positioning function, stable processing can be maintained even with narrow clamping margins, effectively improving material utilization. The discharge belt conveyor is structurally optimized for continuous output, ensuring smooth operation without material jamming and providing reliable support for uninterrupted production.

Overall, Derateck SAP3 1550 punching and shearing compound machine is not a simple aggregation of functions. Instead, it represents a systematic integration of structure, drive, and control systems based on real production workflows. By reducing process fragmentation, lowering labor dependence, and increasing the completion rate of single-cycle processing, the machine helps manufacturers achieve both higher efficiency and lower costs—without compromising processing quality.
