It is intended for businesses that require high cutting quality, strong performance and stable, repeatable operation in every The Digima F1530 3kW is equipped with branded components that enhance durability and cutting performance. The machine includes a RAYCUS laser source, a Raytools AUTO FOCUS cutting head, a Raytools control system, a Schneider servo system, a Japanese Shimpo reducer, H-class linear rails and an industrial TONGFEI / S&A cooling system. The entire unit is built on a heavy-duty industrial steel frame that has been heat-treated for improved stability and long-term resistance to deformation. The machine also provides flexible use of assist gases, allowing the cutting process to be adapted to the material type and the expected edge quality. Oxygen at 1 MPa can be used for carbon steel, nitrogen at 2.5 MPa is intended for stainless steel and aluminium, and compressed air at 1.4–1.6 MPa offers a more economical option for thinner parts. This gives the user better control over cutting quality, process speed and operating costs. As standard, the machine includes features that improve operator safety and protect key components. A laser-head cover helps protect the cutting head from dirt and mechanical damage, while safety barriers create an additional protective zone around the working area, improving safety during intensive production work. Hnodpfszlr Syjx Aa Ejp The Digima F1530 3kW is powered by a 3P 380 V / 50 Hz supply, and the machine itself weighs 2000 kg. It is a modern and efficient fiber laser cutter for companies looking for a solution that combines a large working area, high precision, fast operation and industrial-grade durability. This model is a strong choice wherever reliable production, high cutting quality and future production growth are important.
