Key Components and Motion Control
1. Bed frame
Manufactured by welding sheet metal and tubing, the machine undergoes high-temperature annealing at 600°C, followed by 4.5 hours of heat preservation. After being slowly cooled to 200-300°C in the furnace, it is air-cooled to eliminate internal bed stress. The process includes rough machining followed by precision finishing, significantly enhancing the rigidity and stability of the machine tool while ensuring long-term stable accuracy. Featuring a side-mounted structure with an integrated automatic feeding system, this design effectively improves feeding efficiency and simplifies material handling.
1.1 Rigidness: The bed structure is welded with plates and pipes, and reinforced with multiple ribbed tube plates to ensure transverse and longitudinal rigidity.
1.2 Welding: The welds on both sides are evenly distributed, symmetrically and staggered, to minimize welding deformation.
Annealing Report: Each bed number has an annealing report
2. Crossbeam and X-axis/Z-axis devices
2.1 The crossbeam undergoes annealing treatment to relieve internal stresses, ensuring the rigidity and stability of the laser head's moving components. During operation, limit switches control the travel distance for positioning, while elastic buffer pads at both ends provide mechanical limits to guarantee system safety.
2.2 The Z-axis mechanism primarily enables vertical movement of the laser head. This motion is controlled by the CNC system through servo motors, which drive linear actuators to move the Z-axis slider up and down reciprocally. Both ends utilize proximity switches to limit travel distance, ensuring safe and reliable operation.
3. Cutting Head and Following Part
3.1 Real-time monitoring of the sealed condition in the protected zone effectively extends the service life of the protective mirror and ensures stable production.
3.2 The impact-resistant cutting head design significantly reduces return-to-factory rates, eliminating the need for on-site service visits. Customers can perform replacements independently, resulting in lower maintenance costs.
3.3 A dust cover plate is added to the optical lens area to enhance the sealing grade of the core chamber and prolong the service life of the core lens.
3.4 The system is equipped with a high-precision capacitive sensing automatic tracking system, which enables highly stable Z-axis floating under system control, preventing height errors caused by thermal stress deformation or pipe surface irregularities during cutting.
4. Cooling System
The system employs Hanli, a renowned domestic brand, for its professional laser water chillers, which offer excellent stability and high precision. It features dual-channel temperature control, enabling independent temperature regulation for both the laser and cutting head, thereby ensuring more effective stability of the laser and cutting head. The functions include: water pressure alarm, high/low temperature alarm, voltage alarm, and various fault alarms.

5. Electrical Control System (Bachu Bus)
The electrical control system of the optical fiber tube cutting machine consists of three core components: the Bachu CNC system, servo system, and low-voltage electrical system. The system features a high-performance Bachu CNC system, a Windows-based PC-based CNC platform renowned for its rapid interpolation calculations and intuitive operation. The servo system incorporates imported AC servo motors and drivers, delivering stable performance, dynamic responsiveness, and high load capacity with user-friendly controls. The machine's soft keys enable customized functions across multiple operation modes, reducing physical buttons and simplifying the control panel. All operational functions are displayed via a menu interface, ensuring intuitive operation.
5.1 CNC System
5.2 Advantages of CNC System:
1) The system features real-time bus-based control and adaptive cutting parameters, delivering twice the industry standard efficiency in corner cutting with stable corner-following and reliable cutting quality. It supports partial graphic processing, positioning at any point during stop/pause operations, and starting from any position. Additional features include fixed-height cutting, automatic edge detection, off-board tool engagement, and tool lifting.
2) It supports the separate setting of laser power, frequency, laser form, gas type, gas pressure, and follow-up height for the perforation process and cutting process.
3) Supports segmented perforation, progressive perforation, and pre-perforation. It allows setting separate parameters for the perforation process and cutting process, including laser power, frequency, laser type, gas type, gas pressure, and follow-up height.
4) Flexible and versatile automatic and manual sorting features, supporting partially fixed processing sequences by group. The unique sequence browsing function provides a more interactive view of processing sequences than simulation.
5) Set up the lead wire and cut seam compensation in the way of what you see is what you get. Automatically distinguish the inner and outer mold, and determine the cut seam compensation direction according to the inner and outer mold, and check the lead wire.
6) Unique one-touch calibration for horizontal square pipes, with automatic rotation center positioning.

6. Low-voltage electrical system
The low-voltage electrical system is located inside the electrical control cabinet, serving as the interface for the entire electrical control system. All components required for the electrical control system, including power supplies, relays, circuit breakers, contactors, and servo drive systems, are installed within the electrical control cabinet. The motor used is a bus motor, which reduces the number of wiring lines.
