9-12m Heavy-duty Tube Laser Cutting Machine with Three Chucks ST Series

As a hi-end machine, ST series are suitable for cutting heavy and long tubes, and have a large body that requires big enough workshop. We tend to recommend it to heavy industries requiring large-sized equipment like engineering, heavy and construction machinery. 6-20 [kW] Laser power 9000-12000 [mm] Tube length 20-500 [mm] Tube size 1200-2000 [kg] Tube weight Competitive Strengths Performance Benefits With 3 chucks, the machine witnesses larger clamping force and makes heavy and long tube cutting precision higher. Driven by innovation and practicability, it is forward-looking while solving tube cutting problems. 1. High in cutting ability * Max tube size: 500mm * Max weight of single tube: 2000kg * Cut round, square, rectangular, oval tubes, angle, channel, H-shaped steel, as well as I beam * Deal with high-reflectivity tubes like stainless steel and AL alloy because of its multi-layer anti-reflective structures 2. Cut with 0 tailing Due to 7-axis linkage and reverse cutting of three chucks, 0 tailing will come true for the max tube utilization rate. 3. High-precision cutting Its innovative dynamic 7-axis tube pulling function may correct the tube deformation to a certain degree, just for cutting at high precision. 4. Need less costs of production As for its laser generation, the electro-optical conversion rate reaches over 40%. Electric power and cutting costs will be greatly saved for users. Mechanical Benefits 1. Classic design * This is a large-sized machine, covering a relative large area. * To cut long tube, its control system sits in the middle and cutting area runs through it to facilitate the full-course movement of three chucks, as thus, long tube is handled easily. 2. Autofocus laser cutting head * Small in size and light in weight, with all-optical temperature detection * Autofocus and auto obstacle avoidance functions can make sure of high cutting precision and prevent possible collision. 3. Three pneumatic chucks * Full-stroke chucks mean that they can move at will in whole stroke, which helps to keep tubes stable during cutting * Dual-rail sliding blocks are used to improve the ability to clamp heavy tubes * There is also through-beam sensor that can detect tube position and enable automatic clamping 4. Side-attached machine tool bed * It is designed as triangular, with high stability and large loading capacity * The bed is made of three segments. Each is outfitted with lifting holes to facilitate transport at less costs * Through fine welding, annealing stress relief, secondary aging treatment, as well as precision finishing, it will be full of high rigidity and long service life. 5. Follow-up support * The servo-controlled support can adjust tube supporting height based on actual diameter until tube is coaxial with chucks center. It usually cling to tube surface. * This support is used to prevent low precision caused by long tube sagging and heavy tube’s rigid impact on the machine during unloading. 6. Automatic loading & unloading devices * Loading device, composed of tube conveyor and supporting racks, will feed tubes into cutting area automatically. * The segmented unloading device works with multiple groups of receiving units to adapt to tubes of different lengths. Control System Benefits The intelligent bus-based CNC system is special for three-chuck tube laser cutters. Based on real-time bus system, it allows for faster and more stable cutting of corners. Other special-shaped steels are also handled easily. 1. Automatic nesting software Besides high automation, it can also realize co-edge nesting to minimize cutting times and save raw materials to the utmost. 2. Tube deviation compensation Make low demands on tubes while clamping, raising piercing and cutting accuracy 3. Automatic obstacle avoidance Apply to both chucks and laser cutting head that can prevent collision and need less maintenance Optional Benefits 1. ±45° bevel cutting The machine can cut tubes into ±45° bevel in one go. With less procedures, tube cutting efficiency will be greatly raised. 2. Safety fence The machine may work with safety fence to separate cutting area. It is good for preventing man-machine injury or unexpected shutdown caused by workers’ intrusion by mistake.
