The DF-H model head combination is a dual-servo tool configuration solution for precision processing of flexible materials. It consists of two core modules: an integrated servo oscillating knife and a servo bevel knife, and can be configured with tool holders, circular punches, spindles, CCD vision components, and inkjet heads according to process requirements. This combination targets processing scenarios where the same workpiece requires both contour cutting and bevel or seam slopes. By automatically switching between two servo tools, it reduces tool changes and secondary clamping, improving the forming accuracy and splicing fit of products such as EVA packaging liners and sponge products.
Core Features
- Automatic dual-servo tool switching: Both the oscillating knife and the bevel knife are servo-driven and automatically change tools according to program instructions, allowing contour cutting and bevel processing to be completed continuously within a single clamping.
- Servo oscillating knife cuts soft materials: Suitable for contour cutting of soft materials such as EVA, sponge, and foam, with smooth cuts and good tracking performance on flexible materials.
- Servo bevel knife handles bevels and seams: Can process bevels and splicing slopes on thick materials, with angle and depth controlled by program, providing a consistent mating surface for subsequent splicing.
- Modular head configuration: Modules such as tool holders, circular punches, spindles, CCD vision components, and inkjet heads can be combined as needed, accommodating processes including drilling, milling, visual positioning, and marking.
- Optional CCD and inkjet matching: With CCD vision components, contour recognition and positioning cutting can be achieved; with an inkjet head, marking and traceability can be completed, reducing manual alignment.
Applicable Materials and Industries
This combination is suitable for cutting and bevel forming of soft and semi-rigid materials such as EVA, sponge, foam, and pearl cotton. Typical applications include packaging liners, cushioning pads, sponge products, sports protective gear, shoe midsoles, and display props, and it is especially suitable for processing special-shaped structural parts that require contour cutting combined with bevel splicing.
Selection and Configuration Recommendations
The integrated servo oscillating knife equipped in this combination is directly driven by a servo motor, with a vibration frequency of 3500 rpm and an amplitude of 5mm. The large-amplitude reciprocating punching force is strong, making it suitable for thick cutting of soft materials such as leather, foam, and composite materials.
When a product requires both contour cutting and bevel or seam slope needs, and you wish to reduce tool changes and secondary clamping, the DF-H head combination can be given priority; if single contour cutting is the main requirement, the tool configuration can be simplified. In terms of supporting equipment, it can be combined with roll feeding or sheet feeding systems, nesting and cutting software, and CCD vision positioning to form a continuous workflow from feeding, recognition, cutting to marking.

FAQ
What materials is the DF-H head combination suitable for?
Suitable for soft and semi-rigid materials such as EVA, sponge, foam, and EPE pearl cotton. It is typically used in industries such as packaging liners, cushioning pads, sports protective gear, and shoe midsoles.
How does the dual-servo tool achieve automatic switching?
Both the oscillating knife and the bevel knife are servo-driven and automatically change tools according to program instructions. Tool change time is about 1 second, allowing continuous contour cutting and bevel processing within a single clamping.
What is the maximum bevel angle the servo bevel knife can process?
The bevel knife angle can be program-controlled, with a typical range of 0-45°, angle control accuracy of ±0.5°, and depth repeat accuracy of ±0.1mm, meeting the needs of thick-material bevels and seam bevels.
What role does the CCD vision component play in the combination?
The CCD vision component enables contour recognition and positioning cutting, with positioning accuracy of ±0.05mm. Together with the inkjet head, it completes marking and traceability, reduces manual alignment, and improves processing accuracy.
How should the DF-H head combination be selected?
When a product requires both contour cutting and bevel/seam bevel processing, and you want to reduce tool changes and secondary clamping, the DF-H model can be given priority; if single contour cutting is the main requirement, the tool configuration can be simplified.

The core advantage of the DF-H model head combination lies in integrating contour cutting and bevel machining into a single setup. Traditional processing methods require separate use of an oscillating knife and a bevel knife, and multiple setups lead to accumulated errors, whereas the dual-servo tools automatically switch via program instructions with a tool change time of only about 1 second, significantly improving efficiency. The servo oscillating knife has good followability for soft materials such as EVA and sponge, with flat cuts; the servo bevel knife precisely controls the bevel angle and depth, providing a consistent fitting surface for subsequent splicing. This collaborative operation is particularly suitable for applications requiring special-shaped structural parts and bevel splicing, such as packaging liners and sports protective gear.
Modular design is another major highlight of the DF-H head combination. Users can mix and match modules such as tool holders, circular punches, spindles, CCD vision components, and inkjet heads according to process requirements. For example, adding a CCD vision component enables contour recognition and positioning cutting, with positioning accuracy up to ±0.05mm; combined with an inkjet head, it can complete marking and traceability, reducing manual alignment. Circular punches are used for drilling, and the spindle is used for milling, allowing a single machine to handle multiple processes. This flexibility reduces equipment investment and improves production line adaptability, making it especially suitable for flexible material processing scenarios with multiple varieties and small batches.
When selecting a model, if the product simultaneously requires contour cutting and bevel or seam slope needs, and you want to reduce tool changes and secondary clamping, the DF-H head combination is the ideal choice. If single contour cutting is the main requirement, the tool configuration can be simplified to reduce costs. In terms of supporting equipment, it is recommended to combine it with a roll or sheet feeding system, nesting and cutting software, and CCD vision positioning to form a continuous workflow from feeding, recognition, cutting to marking. In practical applications, servo parameters need to be adjusted according to material thickness and hardness, and tools should be maintained regularly to maintain accuracy. This combination has been widely used in industries such as packaging liners, sponge products, and shoe midsole materials, helping enterprises improve forming accuracy and splicing fit.
