To achieve a low failure rate of horizontal machining centers, the following measures can be taken:

1. Regular maintenance: Regular maintenance of the horizontal machining center, including cleaning, lubrication, inspection of various components, etc., to ensure that the horizontal machining center is in good working condition and reduce the possibility of failure.

2. Use high-quality accessories: Horizontal machining centers use high-quality, reliable parts and accessories, such as spindles, servo motors, transmission systems, etc., to avoid failures caused by parts quality issues.

3. Strict operating procedures: The horizontal machining center formulates strict operating procedures and safe operating procedures to ensure that operators operate the equipment correctly and avoid failures caused by misoperation.

4. Regular inspection: Regularly conduct comprehensive inspections and evaluations of the horizontal machining center to identify potential problems and repair them in a timely manner to prevent the occurrence and expansion of faults.

5. Training operators: Provide professional training and skill improvement for horizontal machining center operators to improve their operating skills and troubleshooting capabilities and reduce failures caused by operating errors.

6. Monitoring system: The horizontal machining center installs a monitoring system to monitor the equipment in real time, detect abnormal situations in a timely manner and take measures to prevent the occurrence and expansion of faults.

7. Quality management: Strengthen the quality management system of the horizontal machining center, strictly control the quality during the production process, ensure that the parameters and performance of the machining center meet the requirements, and reduce the failure rate.

Through the above measures, the horizontal machining center can effectively reduce the failure rate of the horizontal machining center, improve the reliability and stability of the equipment, and ensure the normal operation of the production line and the improvement of production efficiency.
