Used OKAMOTO VG 502 #9086507 for sale

OKAMOTO VG 502 is an automated wafer grinding, lapping and polishing equipment designed by OKAMOTO Corporation, a prominent manufacturer of precision grinding machines. This system fully automates the grinding, lapping and polishing processes to increase manufacturing efficiency, reduce labor costs, and improve quality and uniformity of results. The unit employs a rotary table to hold wafers in one of two orientations and is capable of accommodating up to 32 wafers at once. A programmable liquid dispenser is used to precisely apply the grinding, lapping and polishing compounds as needed. These are then processed via a grinding wheel, a rotatable lapping plate, and a polishing pad. Additionally, different kinds of accessories can be used, such as the "Pepperoni Feeder" to properly feed wafers, and the "Weight Roller" to optimize the lapping process. To ensure accuracy and uniformity of results, a closed-loop control machine is employed. This utilizes a laser interferometer and feedback motor to automatically adjust the rotation speed or axis based on data from the process. Automatic machine diagnostics are also available to detect any errors that may occur during operation. Overall, OKAMOTO VG-502 wafer grinding, lapping and polishing tool offers a highly advanced and automated solution with the capacity to process large batches of wafers in a single operation. With its advanced control features and data collection capabilities, it is the ideal choice for any production environment that requires high-precision results.
