NC cut-off machine is used in corrugated board production to cut the corrugated board web into sheets of the required order size with precise, preset lengths.
Features
- Stores up to 200 order parameters and supports rapid knife specification changes without stopping the machine.
- Utilizes forged steel gears and a keyless shaft connection for high transmission accuracy and zero backlash.
- Cutting knives feature a helical inlaid structure and scissor-type design, providing strong cutting force suitable for various board thicknesses.
- The feeding system adopts a star-wheel pressing structure, ensuring stable and uniformly pressured board conveying.
- Equipped with a brake energy-storage system, delivering average energy consumption at one-third of standard models, achieving over 70% energy savings.
- Built with an independent oil pump and filtration system for lubrication and cooling, extending component lifespan.
- Maximum cutting speed reaches 200 m/min, with sheet-cutting accuracy controlled within ±1 mm.
