It is a new energy-saving and environmentally friendly product, and one of the world’s leading technology products. It is suitable for cutting metal plates such as stainless steel, carbon steel, alloy steel, silicon steel, aluminum, copper, brass, titanium alloy, galvanized sheets, etc. Unmatched Accessibility - Because the machine is an "open type" (without a full protective enclosure), operators have 360° access to the cutting bed. This makes loading raw sheets and unloading finished parts significantly faster and easier, especially when using a forklift or overhead crane. Space Efficiency - The 3015 model is designed with a compact footprint. Without the bulk of a large safety cabin or a dual-shuttle table system, it fits comfortably into smaller workshops where floor space is at a premium, providing a high "power-to-square-foot" ratio. Cost-Effectiveness - Open-type machines generally have a lower initial investment compared to fully enclosed or exchange-table models. They are also easier to maintain, as all mechanical components (rails, racks, and motors) are readily accessible for routine cleaning and lubrication. Efficient and precise cutting of medium and thin plates: • Easy access for loading and unloading the material from all 4 sides; • Auto-focus laser head; • Automatic edge detection; • Nesting included for optimizing the drawings and optimize material usage; • Easy to operate; • CE standard.
