Innovative and sustainable air compressors
Compressed air is one of the important driving forces in production. Xiamen East Asia Machinery Industry Co., LTD. (EAMI), founded in 1991 and headquartered in Xiamen, Fujian Province, has been focusing on the field of air compressors since its inception. The business scope includes research and development, production and sales of air compressors. To meet the increasingly stringent production requirements, EAMI purchased two DMG MORI DMC 75 H units in 2010. Today, there are 42 DMG MORI machines in the workshop, including 30 horizontal machining centers such as the NHX 8000 and several NHC series machines. EAMI also uses vertical machining centers and CNC turning centers. In addition, EAMI invested in two fully automated production lines at the end of 2021, each consisting of four NHC 4000 horizontal machining centers and mobile robots. Again, creative design and system installation are provided by DMG MORI.
DMG MORI offers machine automation systems and training in one stop to ensure steady customer development.
Reflecting on the many years of successful collaboration between EAMI and DMG MORI, EAMI General Manager Wenhao HAN confirmed: "It can be said that DMG MORI has played a pivotal role in the development of EAMI and has provided great support to EAMI along the way. DMG MORI's machine tools are stable, reliable and resilient. Moreover, DMG MORI's expert support and tailored training have proven to increase productivity and drive our steady growth."
High precision machining for oil-free air compressors
In EAMI machining production, chip removal is the key. Chip removal directly affects product quality. It can be said that the requirements for processing machines are very high. In particular, EAMI's new products, such as oil-free dry air compressors, effectively prevent the heating of lubricating oil during air compression, resulting in temperature rise and faster operation. Wenhao HAN said: "This means that the processing accuracy of the core components must be improved to ensure the stability and working life of the air compressor at high speeds."
EAMI process air compressor housings and bearing housings using DMG MORI machining centers, which are the core components of the company's products. The high precision, high performance and high stability of DMG MORI machines fully meet the machining requirements of EAMI and ensure the concentricity, parallelism, perpendicularity, flatness and surface quality of the box work piece, even under harsh working conditions. The geometry of these parts is complex and may deform if they are not clamped correctly. HAN said: "The DMG MORI machining center has significantly improved the machining efficiency and repeatability. The position error of the mold has been reduced from the original 0.04-0.06mm to 0.01-0.02mm, and the concentricity can now reach 0.01-0.02mm, which significantly improves the processing efficiency compared to the original horizontal machining center."
EAMI manufactures air compressor housing using DMG MORI's horizontal machining center. Two production lines produce small and medium-sized work pieces, each of which consists of four NHC 4000 horizontal machining centers. Mobile robots automatically load and unload the machine.
Automatic processing and efficient production
"Automation is the key to reducing staff and increasing efficiency," HAN said. It's all about smart production." Especially in recent years, it has become increasingly difficult to recruit skilled staff. At the end of 2021, EAMI chose a proactive approach to address the challenge of the labor shortage. This is where, in collaboration with DMG MORI, two production lines have been automated for the processing of housing and bearing housings.
The two production lines are equipped with four horizontal machining centers and a mobile robot
Each production line consists of four NHC 4000 horizontal machining centers and a mobile robot that loads work pieces onto pallets and into machine tools, and performs finished part unloading. Moreover, while the machine tool is processed, the machine tool operator can prepare a new pallet, and HAN said in evaluating the two production lines: "The two production lines fully meet the requirements of long-term, unattended production." After the work piece is clamped, the machine can run independently for a long time. These lines can also operate unattended at night." Can be operated by multiple machines. Actions speak louder than words: a production line requires only one operator and is at full capacity 24 hours a day. It used to take four employees to work two shifts.
Automated multi-variety and small-batch production
The automatic production project for bearing housings and housing demonstrates forward-looking production technology for EAMI. EAMI can now mass-produce a wide range of small workpieces. Moreover, most of them are produced in small batches. Thus, DMG MORI meets the flexible production requirements. In addition, DMG MORI has deepened its expertise in the interaction of hardware and software in automated production. The two sides plan to continue to maintain mutually beneficial and win-win cooperation.
Working together for a green future
A wide range of models, high quality machine tools, technical support and reliable customer service are the main reasons why EAMI chose to partner with DMG MORI. The shared vision is another foundation for continued cooperation in the future, emphasized HAN: "DMG MORI is a multinational company with a long history and has always maintained a strong creativity. The same is true of EAMI. Working with DMG MORI, a professional partner allows us to benefit from the strength of a large company that, like DMG MORI, will continue to innovate and strive for excellence, especially in the area of sustainability." Since the beginning of 2021, DMG MORI has become carbon neutral, from raw materials to machine delivery. As a result, DMG MORI is a veritable leader in sustainable green development in the machine tool industry. In this regard, EAMI produces sustainable air compressors, such as permanent magnet air compressors with variable frequency control. Wenhao HAN looks to the future: "We hope to maintain close contact with DMG MORI, deepen our cooperation and work hand in hand to promote green development together."
