In 2024, Bulls launched a new series of center-pressure quick-locking polishing fixtures, including the MMC/APC-24KZ model. This series is fully compatible with the widely recognized Bulls-5000 and Bulls-6000 fiber polishing machines. Through its patented structural design, it effectively addresses the long-term stability issues seen in conventional quick-locking fixtures, achieving precise product positioning and highly efficient clamping. It provides users with a more reliable, high-quality polishing solution.
Bulls Center-Pressure Polishing Solution, proven through extensive market application, is widely recognized for its ease of operation, stable pressure control system, and broad process adaptability. In the course of our development, we not only retained the inherent advantages of this technology, but also integrated our patented pressure-compensated quick-locking polishing fixtures to achieve highly stable 3D performance data for MMC connectors. Enhancing operational convenience and production efficiency serves as a core objective of this solution.
This technology has been adopted by multiple leading high-end connector manufacturers and has become a reliable choice for high-precision and high-consistency polishing operations.

Challenges
To meet the growing demands of high-density fiber deployment and miniaturization, the MMC connector has emerged as an important choice in AI-related applications. It maintains the same connection efficiency as the MT connector while achieving a significantly smaller form factor. However, this miniaturized design also introduces unique polishing challenges: due to the reduced connector size, smaller end-face contact area, and minimized positioning references, traditional fixtures often suffer from unstable positioning and insufficient structural rigidity. This leads to increased angular deviation and noticeable fluctuations in 3D parameters during polishing, which severely impacts insertion performance and product yield.
To address these industry pain points, after several months of dedicated R&D, we developed the MMC/APC-24KZ series quick-locking polishing fixtures. These fixtures are specifically optimized for MMC and other micro-connector clamping requirements, featuring an enhanced structural framework and precision positioning interfaces to ensure more accurate alignment control and superior anti-deformation capability—improving polishing stability at its root.
When equipped with the widely recognized Bulls-5000 and Bulls-6000 fiber polishing machines, this fixture series provides enterprise users with a high-consistency MMC polishing solution. It effectively regulates angle and 3D parameter variation, improves yield rates, enhances process reliability, and supports customers in achieving better performance and cost efficiency as fiber connectors continue to advance in miniaturization.
Overall System Architecture and Core Advantages
The dedicated quick-release polishing fixtures are a highlight of this solution. The newly introduced MMC/APC-24KZ series quick-release polishing fixtures are designed to achieve a unified balance of precision, stability, and operational efficiency. In response to the rapidly evolving fiber-optic communications industry and the increasing demand for high-throughput production of multi-fiber connectors, we have developed a new generation of high-performance quick-release polishing fixtures.
Compared with traditional fixtures that commonly experience rapid wear, poor adaptability, unstable pressure control, heavy reliance on operator skill, and short service life, our fixtures incorporate a low-wear transmission mechanism combined with pressure compensation, significantly extending service durability. The flexible positioning and floating clamping system effectively accommodate tolerance variations across different products, ensuring consistent and uniform clamping pressure. While enabling fast loading and unloading, the design fundamentally prevents deformation and parameter deviation caused by pressure fluctuations, providing a stable and reliable solution for high-precision fiber end-face polishing.


Market Feedback
Since its introduction to the market, this solution has been widely recognized by industry users for its exceptional polishing precision and stable production efficiency. Multiple connector manufacturers adopting the solution have reported breakthrough performance in MMC connector polishing: the end-face interference pass rate has significantly increased, the fluctuation range of 3D parameters has been notably reduced, and overall product yield has achieved systematic improvement. Meanwhile, the quick-release fixture design shortens the clamping time per operation by approximately 50%, greatly enhancing overall production line efficiency.
To date, this solution has been successfully deployed in several large-scale fiber optic component manufacturing facilities, becoming a core process guarantee in high-density connector mass production. Its performance and adoption fully validate its unique value in enabling miniaturization, high throughput, and high-consistency polishing.
We remain deeply committed to the research and optimization of polishing processes in the fiber-optic and related application fields.
