The ACA-style machine head combination is a modular processing head assembled from two single-knife-seat modules and a central circular punch module, used to complete standard circular hole punching while cutting contours.
The ACA-style machine head combination adopts a mixed layout of “single knife seat + circular punch + single knife seat,” assembled from two independent knife-seat modules and a central circular punch module. The two knives respectively handle contour cutting and special-shape cutting tasks, while the central circular punch module achieves one-step punching of standard circular holes such as label holes, hanging holes, and ventilation holes, reducing secondary processing steps. This combination targets processing scenarios that require forming regular circular holes while cutting contours; hole positions and tool paths work together under the same positioning datum, helping maintain relative accuracy between hole positions and outer shapes.
Core Features
- Independent dual knife-seat configuration: The front and rear single knife seats can respectively clamp oscillating knives or oblique cutting knives, with clear division of labor between contour cutting and special-shape cutting, reducing tool change frequency and suitable for continuous processing of mixed contours within the same layout.
- One-step forming by central circular punch: The circular punch module is located between the two knife seats; standard circular holes are punched synchronously with cutting, and hole positions are determined by the same motion datum, resulting in clean cuts without obvious burrs and eliminating subsequent drilling or punching steps.
- Collaborative positioning of holes and contours: The circular punch and knife seats share the same machine head coordinate system, so the position consistency of hole positions relative to cutting contours is good, suitable for shoe material and luggage components with matching requirements for hole spacing and edge distances.
- Modular assembly structure: Both knife seats and circular punches are modular units, and clamping and combination methods can be adjusted according to process requirements; they can later be combined with CCD vision components, inkjet heads, and other modules to extend marking and positioning functions.
- Compatible with flexible roll materials and sheets: The machine head combination is designed for flexible materials such as shoe materials, luggage fabrics, and packaging labels; cutting and punching are completed within the same process, helping maintain material flatness and processing rhythm.
Applicable Materials and Industries
This combination is suitable for materials such as leather, PU, microfiber, mesh fabric, non-woven fabric, cardboard, label paper, foam, and some composite fabrics. Typical applications include shoe material cut pieces (such as shoe uppers and breathable holes in insoles), luggage fabrics and accessories, hanging holes and handle holes in packaging labels, garment accessories, and hole punching for automotive interior parts. For orders that require batch forming of standard round holes while cutting outlines, this combination can complete contour and hole processing in a single operation.
Selection and Configuration Recommendations
If the processing requirements are mainly “contour/irregular cutting + standard round hole forming,” and the hole specifications are relatively fixed with high hole position accuracy requirements, the ACA model head combination is more suitable; if hole types are diverse or hole diameters need to be changed frequently, the replacement convenience and spare part configuration of the round punch module can be evaluated. In terms of configuration, it can be used with a roll feeding system, automatic deviation correction device, and layout cutting software to achieve continuous feeding and hole position layout optimization; for scenarios with higher alignment accuracy requirements, a CCD vision component can be added for mark recognition and compensation.

FAQ
What materials can the ACA machine head combination process?
It is suitable for flexible materials such as leather, PU, microfiber, mesh fabric, non-woven fabric, cardstock, label paper, foam, and some composite fabrics.
Can the circular punch module quickly change different hole diameters?
Yes. The circular punch module is a modular unit; the hole diameter can be adjusted by changing the punch. It is recommended to keep spare punches of commonly used specifications to shorten changeover time.
How does this combination ensure the accuracy of hole positions and contours?
The circular punch and the knife holder share the same machine head coordinate system, and the hole positions are determined by the same motion reference. The positioning accuracy can reach ±0.1 mm, ensuring the relative accuracy of hole positions and contours.
Does it support use with a CCD vision system?
Yes. The machine head combination reserves expansion interfaces and can be equipped with CCD vision components for mark recognition and position compensation, improving alignment accuracy.
What is the maximum punching diameter?
The standard circular punch module has a maximum punching diameter of 10 mm. Special specifications can be customized beyond this range.
