Used SPEEDFAM 9B-5L #293641135 for sale

SPEEDFAM 9B-5L is a wafer grinding, lapping, and polishing equipment that is widely used in semiconductor production and optics manufacturing. The system is designed to create superior high-precision flat surfaces on a variety of materials, such as silicon, sapphire substrates, and metals. The unit has a three-station configuration that incorporates a rotary grinding mechanism, a stationary grinding mechanism, and a lapping and polishing mechanism. The rotary grinding stage utilizes a diamond grinding wheel that is mounted onto the main spindle, allowing for precise control of the grinding pressure and speed. The stationary grinding stage features a unique air-bearing machine that enables frictionless operation over a wide range of forces, ensuring high-precision machining. SPEEDFAM 9B5L has a fully automated lapping and polishing stage, which uses diamond or alumina abrasives under a controlled liquid pressure distribution tool. This allows for accurate control of the uniformity and depth of the surface lapping and polishing. The asset also has a rigorous gas purification model that uses heavy-duty nitrogen scrubbers and exhaust filters to remove particles and gases from the air, ensuring clean, contaminant-free working conditions. 9 B-5 L equipment also includes a sophisticated motion-control package that regulates all movements within the system, including the grinding and polishing stages. This motion-control package consists of an industrial-grade PC-based CNC controller, an encoder-based closed-loop control unit, and an advanced servo motor drive machine. Overall, 9B5L tool is a highly sophisticated, automated asset designed to create superior flat surfaces on a range of materials. It has a sophisticated motion-control package that allows for precise control of the model, as well as a robust air-bearing equipment for frictionless operation. The system also has a unified exhaust unit and a nitrogen scrubber that ensures clean, contaminant-free working conditions.
