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.
