Key Structure and Motion Control
1. Machine Bed
The machine bed adopts a split structure, consisting of the main bed and the unloading bed. It is welded from steel plates and tubes. After welding, it undergoes high-temperature annealing at 640°C, is held for 4.5 hours, and then slowly cooled in the furnace to 200–300°C before being taken out for air cooling. This process effectively eliminates internal stress in the machine bed.
After stress relief treatment, the bed is subjected to rough machining followed by finish machining, which greatly improves the rigidity and stability of the machine and ensures long-term stable precision.
The machine adopts a side-mounted structure and is equipped with an automatic loading system, which effectively improves loading efficiency and makes unloading more convenient.
Rigidity: Welded from steel plates and tubes, the bed structure is connected by multiple reinforced ribs between the longitudinal and transverse sections, ensuring high rigidity.
Welding: The weld seams on both sides are evenly distributed and arranged symmetrically in a staggered pattern to reduce welding deformation.
Annealing Report: An annealing report is available for each machine bed.
2. Loading and Unloading System
The complete loading system consists of a conveyor chain and loading supports. The loader has a maximum load capacity of 1,200 kg and can load single workpieces up to 200 kg.
It is capable of automatically feeding multiple batches of the same type of tubes for cutting. The entire process is carried out automatically, helping to reduce labor costs.
The standard machine supports storage of up to 5 workpieces for continuous feeding. Capacity for more than 5 workpieces is available on request.
Servo motor + pneumatic flexible floating support follows the tube during processing, ensuring the tube does not swing and preventing accuracy deviations caused by tube movement.
3. Beam and X-Axis / Z-Axis Devices
3.1 Beam
The beam is subjected to annealing treatment to eliminate internal stress, ensuring the rigidity and stability of the moving components of the laser head. During operation, the travel is limited by limit switches, while elastic buffer pads at both ends provide mechanical limit protection, ensuring safe system operation.
3.2 Z-Axis Device
The Z-axis device is mainly used to achieve the up-and-down movement of the laser head. This vertical motion is controlled by the CNC system, which drives the servo motor. The motor then drives the linear module, causing the Z-axis slide plate to move up and down repeatedly. Proximity switches are installed at both the upper and lower ends to control the travel, ensuring safe and reliable operation.
4. Cutting Head and Follow-Up System
4.1 The sealing performance of the protective area is monitored in real time, effectively extending the service life of the protective lens and ensuring stable production.
4.2 The cutting head features an anti-collision design, which effectively reduces the probability of factory return. No on-site after-sales service is required, as customers can replace it by themselves, resulting in lower maintenance costs.
4.3 A dust-proof cover is added to the optical lens area to improve the sealing level of the core chamber and extend the service life of the core optical lenses.
4.4 Equipped with a high-precision capacitive sensor automatic tracking system, the cutting head can achieve highly stable Z-axis floating under system control, preventing height errors caused by thermal stress deformation during tube cutting or by uneven tube surfaces.
5. Cooling System
A Hanli, a well-known domestic brand, is used for the professional laser chiller, featuring excellent stability and high precision. It is equipped with a dual-circuit temperature control system, allowing separate temperature control for the laser source and the cutting head. With dual-temperature and dual-control design, it more effectively ensures the stability of both the laser source and the cutting head.
Functions include: water pressure alarm, high-temperature alarm, low-temperature alarm, voltage alarm, and various fault alarms.
