3、 Product structure features
1. The frame is welded with steel plate as a whole, with good rigidity and high strength. The internal stress is eliminated by integral tempering treatment to ensure the long-term stability of the overall accuracy of the machine tool.
2. Rexroth hydraulic control system and Netherlands delemda53t numerical control system are adopted to ensure stable control performance.
3. The main motor is a high-performance servo motor, which adopts full closed-loop electro-hydraulic servo control to supply oil on demand, with high efficiency and low oil temperature.
4. Both sides of Y1 and Y2 axes are equipped with high-precision grating ruler, which can control the positioning accuracy of sliding block ± 0.02mm and repeated positioning accuracy of ± 0.01mm.
5. The x-axis is the rear stop shaft, which is driven by servo motor and precision ball screw, and the positioning accuracy is less than ± 0.1 mm.
6. The precision of feeding and discharging is less than or equal to ± 0.1 mm.
7. The main components of electrical control are Schneider, and the main seals of hydraulic system are imported from Europe and America
4、 After sales service system
（1） Solemn commitment and strict system (see the regulations on after-sales service in ISO9001 quality assurance system for details)
1. Our company is an enterprise that has passed the ISO9001 quality system certification. Three Guarantees will be implemented within one year after the completion of equipment commissioning. If the commissioning and acceptance work fails to be completed due to the user's reason within 3 months after the delivery of the equipment, it will be deemed that the user has passed the acceptance, and the equipment will automatically enter the warranty period. The contract will continue to be implemented according to the relevant terms after the acceptance.
2. When the maintenance service personnel go to the user for service, they must make detailed records of the completed maintenance tasks and the methods of solving problems, and the users will feedback their opinions to the company, and strictly control and assess the work quality of the service personnel.
（2） Full time service team ensures the operability of service network
1. Users send operators to our company, or our after-sales personnel go to the demander's factory area for free training on operation, maintenance and maintenance of operators until they can operate the machine independently.
2. The full-time after-sales service team, the service hotline is opened 24 hours, and there are several offices in the country, which can make timely response to the service requirements put forward by users, reply within 8 hours in case of failure, and arrive at the customer's factory within 24 hours.
