Openex’s investment in high-quality welding fabrication is a cornerstone of its success. Openex’s facilities house specialized equipment, including CNC machine centers such as 3D laser cutting machines, Robotic torch cutters (no need for further chamfering), Robotic welding machines, and some imported welding machines of high performance.

But the good machine fleet alone cannot bring about excellence. Openex’s team of experienced professionals is the second strength. The company’s methodical approach to complex problems was demonstrated by a high-profile recent project. Openex has a team of experienced senior staff who are dedicated to the most challenging tasks. Each of them has over 7-8 year’s experience. They oversee each production phase. The depth of experience ensures that each detail is treated with care, from the initial design process to the final inspection. Openex is defined by the powerful synergy created when this human element is combined with technology prowess.

Case study: Precision Fabrication &Machining for High-Complexity Chambers

Openex’s capabilities are perfectly illustrated by a recent project that involved the manufacture of large vacuum chambers with diameters over 1.35 meters. The project was different from the usual work and presented a unique set of challenges that required innovative approaches as well as a high level of technical expertise. These vacuum chambers weighed more than one ton. It requires:

• High-precision metal forming–plate rolling
• High-quality welding, which requires a helium test for no leakage
• High-precision machining of the groove with roughness under 1.6 1.6Microns, so that the O-ring on it can have good performance to stop leakage
• High quality of painting finish

Background and Requirements:

Openex was commissioned by a leading flywheel energy storage developer to fabricate these vacuum chambers. The flywheels inside the chamber rotate at high speed, over 10000 rpm, if the chamber is not in high vacuum, the flywheels will stop for a while due to air friction; therefore, the roundness of the chamber wall and the end rings must be very precise, and there must not be even the slightest welding defect in the longitudinal welding seam to prevent external air from entering the chamber through the welding seam. In addition, the chamber and the top plate are sealed with an O-ring; the groove where the O-ring is placed must be smooth (turning to below 1.6 microns) enough to avoid air leakage.

Challenges and Solutions

The project was unique, in part because it had spatial and interdependent dimensions. It meant that any error in one dimension would cascade to affect the entire structure. This complexity required a high level of expertise both in programming and operation.

Process Design and Programming: 

Openex’s team used advanced software to create an exact programming blueprint for this intricate machining process. Toolpath simulations have been conducted to reduce the risk of error, especially for the delicate slots in the dovetail joints. The team also implemented compensation strategies that counter the deformation often associated with welded structures, thus ensuring the integrity of the final product.

Tooling and Equipment:

Mitsubishi MVR40 was the keystone of the project. The robustness and precision of the machine provided the foundation needed for this complex project. The team chose high-rigidity and wear-resistant drills and milling tools to complement the machine. This ensured sustained performance during the long machining operations.

Operation and Coordination: 

At every stage, meticulous execution was crucial. Operators used standardized workflows to collect real-time data, collaborate with programmers, and make immediate adjustments. To ensure safety and precision, the team closely monitored how auxiliary heads were used.

Process & Results:

The machining of the vacuum chamber took 4.5 days due to a thorough plan and coordinated coordination. The process included a sequence of meticulous preparation, rough machining and precision machining. The first chamber met all the customer’s requirements and achieved industry-leading standards in both perpendicularity and flatness. The success of this project not only met the customer’s requirements but also gave the Openex team valuable experience that will be used in future batches to improve processing efficiency. This case study is a testament to Openex’s technical abilities, showing that they are leaders in complex welded structure machining.

Inspection and Measurement:

The inspection is conducted by a specially designed and configured device to check the leakage.

The dimension tolerance is measured by a large and precision CMM

The success of this project reflects broader trends in the manufacturing industry. Globally, the welding and precision machining industry is experiencing a robust growth period, driven by an increasing demand for tight-tolerance, specialized components from key industries. This growth comes with significant challenges and trends that will define the future of this industry.

• Automation and robotics: Robots are taking on repetitive, dangerous jobs while humans focus on complex tasks. Openex, with its advanced equipment and expert team of engineers, is one company that has successfully integrated this human-machine cooperation.

• Digitalization and smart manufacturing: Industry 4.0 has transformed the factory floor. The real-time data collected by sensors on welding equipment and machining machines can be used for monitoring processes, predicting maintenance needs and optimizing production. This digital approach is essential for a project as complex as the vacuum chambers. Openex’s rigorous testing and process design align perfectly with this trend.

• Materials of the Future and Specializations: As industries such as aerospace and energy progress, so too does the need for components made with new high-performance alloys. To maintain the unique properties of these materials, they often require specialized techniques for welding and precision machining. This shift in the industry is moving away from a model that is commoditized and towards one of high-value specialized work. Openex’s experience in handling large, complex components allows it to perfectly meet the needs of clients who work with these advanced materials.

• Quality Assurance and Certification–In a global marketplace, compliance and quality are of paramount importance. ISO 3834 is a great example, as it opens doors to European markets whileproviding a guarantee of quality and safety. The reputation of a company for strict quality control is more important than formal certifications. This was demonstrated in the case studies with their meticulous inspections and close tolerances.

The vacuum chamber is more than a success story. It is an example of how Openex has tackled the most challenging challenges in manufacturing and seized the best opportunities. The company’s focus on professionalism is demonstrated by combining advanced technology with a skilled workforce and a customer-centric attitude. Openex, as the industry continues its evolution, is prepared to lead, bringing visions to life with unmatched precision and expertise.
