On November 11, 2020, the opening ceremony of the second phase of Bosch Rexroth (Xi'an) Electronic Drive and Control Co., Ltd. was grandly held. With the completion of the second phase of the project, the Xi'an plant will become the Group's overall supplier of global intelligent manufacturing and industrial automation solutions, and Bosch Rexroth will provide the Chinese market with a richer and more locally tailored factory automation portfolio and Industry 4.0 turnkey solutions. At the same time, as the Bosch Rexroth Group's global future factory demonstration base, the Xi'an plant has taken the lead in helping China's manufacturing industry to embrace the arrival of the intelligent and connected era.
As a leader in Industry 4.0 and the foundation of the factory of the future, the official production of the second phase of the Bosch Rexroth plant in Xi'an is a milestone for the Bosch Rexroth Group. Liu Huowei, Chairman of the Board of Directors of Bosch Rexroth China, Thomas Le, Head of Factory Automation of Bosch Rexroth China, An Yingli, Head of Bosch Rexroth Xi'an Plant, and Uweleonhardt attended the opening ceremony. A number of Bosch Rexroth strategic partners and channel partners were also invited to participate in the event, and the guests watched the classic value stream of multiple varieties, small batches and zero switching on the spot. Get an up-close look at Rexroth's leading factory automation products and solutions.
As the overall technology of intelligent manufacturing and factory automation of Bosch Rexroth Group, the second phase of the Xi'an plant has expanded and improved the three major product technologies of automation and electrical control, linear transmission technology and assembly technology according to the original product business and production equipment, combined with the Chinese market and customer needs
In automation and electrical control, on the basis of the development and production of the original inverter, MS2S motors and AMdrives system solutions have landed in China, realizing the product strategy of serving the local area and providing better services for local customers. In particular, Bosch Rexroth launched the hegemonic work ctrlXAUTOMATION automation platform, which breaks through the traditional boundaries, and through the strong Sino-German R&D team, the series products have gradually fallen into the Xi'an factory, bringing new convenience and flexibility to the development of China's automation industry.
In linear transmission technology, on the basis of the original slider production, the second phase of the Xi'an factory project layout introduced the original Germany guide rail production line, shortening the delivery cycle of the slider and guide rail this business unit fist combination product to 2 weeks, the guide rail has a monthly production capacity of 35,000 meters, and some models have achieved 100% localized procurement, laying the foundation for faster response to customer needs.
In the assembly technology business unit, 10 production lines have been produced for the first time in the second phase of the Xi'an plant, and the product line has been integrated and continuously improved by local procurement, and the product delivery efficiency has been greatly improved.

Operation of Rexroth pressure reducing valves
1. It is necessary to avoid the retention of dirt and debris into the pressure reducing valve pressure reduction guarantee system. The pipe network of the pressure reduction system of the new or renovated project is likely to leave sand, hemp silk and debris. Before putting into operation, water flushing should generally be carried out, and after meeting the cleaning requirements, the pressure reducing valve and filter element should be finally installed.
