Unlocking Peak Productivity: How Automatic Loading and 1.5G High-Speed Cutting Transform Tube Processing In the competitive landscape of industrial manufacturing, maximizing throughput without sacrificing precision is the ultimate goal. For tube cutting operations, this translates to two critical factors: the speed of the cutting process itself and the efficiency of material handling. Modern laser tube cutting machines are addressing this directly through the integration of advanced automatic loading/unloading systems and achieving unprecedented linkage speeds, such as 1.5G acceleration. The Power of 1.5G Maximum Linkage Speed The term "1.5G linkage speed" refers to the axis acceleration capability of the cutting head. Here, 'G' represents the acceleration due to gravity (9.8 m/s²). A 1.5G acceleration means the machine's cutting head can achieve extreme rates of change in speed and direction, dramatically reducing non-cutting time. Traditional machines with lower acceleration spend a significant portion of their cycle time merely moving between cutting points. A machine capable of 1.5G acceleration minimizes this idle travel time drastically. It can make sharp directional changes and traverse the length of a tube at remarkable speeds. This is achieved through a combination of high-torque, direct-drive servo motors, lightweight but rigid structural components to reduce inertia, and sophisticated CNC controllers that process trajectory data instantaneously. The result is a laser head that is almost constantly cutting, leading to a substantial boost in overall efficiency, especially for complex patterns with numerous start-stop points. Seamless Operation with Automatic Loading/Unloading Raw material handling is a major bottleneck. Automatic loading/unloading systems eradicate this bottleneck. Semi-Automatic Loading often involve a manual initial stack placement onto a feeding rack, from which the machine automatically picks up tubes one by one. Finished pieces are then ejected into a collection bin. This is ideal for lower-volume or mixed-batch production. Fully Automatic Loading represent the pinnacle of hands-off operation. They integrate a robotic arm or a dedicated gantry loader with a material storage rack. The system can run for hours, automatically fetching raw tubes, feeding them into the machine, and then sorting the cut pieces onto different racks or conveyors without any human intervention. This is crucial for high-volume, lights-out manufacturing. Qihai Factory: Engineering Excellence with Servo-Driven Follow-the-Cut Support While speed and automation are crucial, true technical prowess lies in the details of integration. This is where the Qihai Factory distinguishes itself. A standout feature of their solutions is the servo-driven follow-the-cut support system. During high-speed cutting, especially with long or slender tubes, sagging or vibration can occur, leading to inaccuracies. Qihai's system employs synchronized servo motors on the support units that actively and precisely follow the movement of the cutting head along the length of the tube. This provides continuous, stable support right at the point of cutting, ensuring exceptional precision even at the maximum 1.5G speed.

Servo Follow-Up Unloading Table: Revolutionizing Laser Tube Cutting Support and Anti-Sagging In the realm of industrial laser tube cutting, precision is paramount. However, a persistent challenge has been managing the unsupported weight of the tube after the cut is made, which can lead to sagging, scratching, or even catastrophic drops that damage both the product and the machine. Addressing this critical issue head-on, the innovative Servo Follow-Up Unloading Table has emerged as a game-changing solution. The Qihai Factory, a leader in advanced laser machinery, has perfected this technology, offering clients unparalleled support and technical sophistication. The Principle: Active Support to Prevent Sagging The core function of the Servo Follow-Up Unloading Table is to provide dynamic, intelligent support to the tube throughout the cutting process. Unlike a static table that merely catches the fall-off part, this system is an active participant. Synchronized Motion: The system is integrated directly with the CNC (Computer Numerical Control) of the laser tube cutting machine. It receives real-time data on the cutting head's position along the length of the tube. Intelligent Anticipation: As the laser head makes a cut, the system's PLC (Programmable Logic Controller) anticipates the exact moment and location where the severed section of the tube will be released. Servo-Driven Action: A high-precision servo motor instantly drives the unloading table (or supporting fingers/rollers) to move synchronously with the cutting process. Just as the cut is completed, the table is already perfectly positioned directly beneath the new end of the remaining tube and is ready to catch the cut-off piece. Elimination of Gravity's Impact: This "follow-up" action eliminates the moment of free fall. The freshly cut end of the long tube is immediately supported, preventing any downward flex or sag. Simultaneously, the cut-off piece is gently and securely received on the table, which then retracts to unload it without causing scratches or dents. Qihai Advantage: Technical Mastery for Uncompromising Quality While the concept is brilliant, its execution demands exceptional engineering precision. This is where the Qihai Factory distinguishes itself. Qihai's implementation of the Servo Follow-Up Unloading Table is not a mere add-on; it is a deeply integrated subsystem. Qihai engineers have developed proprietary algorithms that ensure flawless synchronization between the servo table and the laser cutter's motion. The system accounts for variables such as tube weight, diameter, and material to adjust its support force and speed, guaranteeing a seamless and gentle "catch" every time. This meticulous attention to detail prevents micro-scratches, maintains the geometric integrity of the tube, and is absolutely critical for processing expensive materials like stainless steel or aerospace-grade alloys. For clients, this translates to tangible benefits: zero post-cut deformation, a flawless surface finish, and significantly reduced operational risks. It enables fully automated, high-speed cutting of long tubes without manual intervention for support, dramatically boosting productivity.

What is Zero-Tailing?Zero-Tailing refers to a optimized production methodology where the tube cutting process is planned and executed to virtually eliminate leftover tailings. This is achieved through advanced nesting software and machine functionalities that maximize material utilization from each standard length tube. The objective is to ensure that the final remnant is either long enough to be used as a primary part or so minimal that it is classified as negligible scrap, rather than a wasteful tailing. In conventional tube cutting processes, the workpiece is typically held by a rear chuck that rotates and moves it forward for sequential cutting. A portion of the tube remains gripped by the chuck jaws, and the cutting head cannot infinitely approach these jaws due to physical constraints. The un-cut section between the cutting head and the rear chuck jaws is termed the "tail length" or "tail material." This leftover segment often goes to waste. For instance, if a tube cutter has a tail length of 25cm, then in a 6.5-meter tube, 4% of the material is wasted. Cutting 200 tubes a day could mean nearly 50 meters of material lost. How to Reduce Waste of Tube Cutting: Achieve Zero Tailing with Qihai Factory In the world of industrial manufacturing, tube cutting waste—often called "tailings" or "tail material"—represents a significant source of material inefficiency and unnecessary cost. However, with Qihai Factory's advanced laser tube-cutting technology, achieving zero tailing has become a practical reality, offering clients unparalleled material utilization and technical support. The Path to Zero Tailing: Qihai FactoryKey Technological Strategies Enlarged Front Chuck Bore Diameter: By allowing the tube held by the rear chuck to pass through the front chuck, the physical distance between the cutting head and the rear chuck jaws is reduced. This can decrease the tail length to 17cm, achieving a 97% material utilization rate. Optimized Chuck Structure: The front chuck's width is minimized to its extreme, further shortening the gap for the cutting head to access. This can reduce the tail length to 13cm, boosting the material utilization rate to 98%. Dual X-Axis Design for Jump Cutting: An industry-first in some national contexts, this design enables the cutting head to "jump" between the front and rear chucks for cutting. This drastically minimizes the distance to the rear chuck jaws, slashing the tail length to an impressive 8cm and raising the material utilization rate to 99%. Breakthrough Four-Chuck Design for Zero Tailing: The most significant leap comes from Qihai Factory's innovative adoption of a four-chuck system. This design enables the tube to be reversed during cutting. By transferring the holding point, no section of the tube remains permanently gripped and out of the cutting head's reach. This breakthrough achieves a 0mm tail length, enabling 100% material utilization and true zero tailing cutting.
