Used SPEEDFAM 18B #293770302 for sale

SPEEDFAM 18B is a premium grade wafer grinding, lapping and polishing equipment. Created by SPEEDFAM Corporation, it has been designed to precisely grind and lap the laser grooves of wafers in a return-to-scale configuration at high speed and accuracy. Featuring water cooled surface platen for robust and efficient grinding, the precision engineered 18B enables reliable and repeatable results. The master platen design is capable of producing parts with accuracies ranging from 0.0005" to 0.003" and also ensures high precision lapping and polishing of these wafers. This system allows effective control over the motion of the grinding/lapping surface to ensure an optimized result while suppressing unnecessary vibration and heating. SPEEDFAM 18B also includes a unique grinding, lapping and polishing base with a motor drive, electronic pressure control unit and fine ceramic grinding wheels. With an operating environment which is entirely temperature, light and humidity controlled, the unit allows for a unified and consistent process for multiple wafers. The ultra-precision grinding/lapping head is designed for superior control over tooling, cutting pressure and grinding/lapping speed. The base features a powerful AC servo motor, fine CeramTec grinding wheels, and a stable, heavy duty frame to ensure high accuracies while simultaneously mitigating heat generation. 18B also includes a variable speed motor drive machine with electronic pressure control and a Polithin polishing head control unit. The Polithin unit is specially designed to reduce the diamond grinding force and abrasive pressure on the wafer surfaces, and also offers a wide range of polishing speeds for high precision results. Together, these components make up a high performance wafer grinding, lapping and polishing tool, capable of meeting a wide range of production demands and achieving the highest quality results. With a robust two-axis master plan design, SPEEDFAM 18B is a reliable asset for lapping and polishing wafers with high accuracy, at high speed and with repeatability.
