The defining feature of an intermittent die cutting machine lies in its stop-start motion, governed by a microprocessor that coordinates feed and cut cycles with 0.001-second precision. When the material—say, a 0.15mm thick paperboard—reaches the cutting station, a servo-driven clamp holds it firm with 5N of force, preventing even 0.02mm of slippage during the pause.
The die plate, typically made of hardened steel, houses blades with a 32-degree edge angle. These blades are mounted on a spring-loaded base that compresses 0.3mm upon contact, absorbing excess force to avoid over-cutting. A tiny pressure sensor beneath the anvil registers changes as small as 0.1kPa, adjusting the downward stroke of the die by 0.05mm to maintain consistent edge quality across varying material densities.
A critical micro-component is the camshaft that triggers the pause. Its lobes are machined to a surface finish of 0.8μm, ensuring smooth transitions between motion and stillness. This minimizes vibration, which could otherwise cause 0.03mm misalignments in intricate cuts—like the tiny perforations on a medication blister pack.
Lubrication is equally precise: a peristaltic pump dispenses 0.05ml of food-grade oil every 100 cycles to the cam bearings, reducing friction without leaving residue that might contaminate sensitive materials such as candy wrappers. This attention to micro-details ensures each cut matches the last, even after 100,000 cycles.
