OKAMOTO GNX 300P is a high performance wafer grinding, lapping and polishing equipment. It is designed with precision technology to help achieve demanding process requirements. It boasts a wide variety of customizable settings that enable users to fine-tune the machine's operations to best suit their specific production requirements. OKAMOTO GNX300P has a touch-free structure which allows its motor-driven point contact wheel and special-form working surface to move in both the X and Y axes. This allows for efficient use of the available space and allows easy operation during loading and unloading of the machine. The high-speed brushless grinding spindle further increases the accuracy and speed of the machine's work. The device consists of two main modules, the work unit and the loading automation unit. The work unit consists of a main spindle motor, a touch-free grinder spindle, a chip turning disc, an air driven chuck, and a coolant pump. The loading automation unit features a wafer aligned loader, cassette lift, and a cassette shuttle. It also has support components such as a spindle monitor and a vibration monitor. GNX 300P features a completely enclosed design, making it safe for use in a cleanroom environment. It is equipped with an exhaust system which ensures that harmful particles and gases produced during operation are removed from the work environment. The entire unit is mounted on a vibration isolator table, for minimized vibration and higher accuracy of production. GNX300P is made of top-quality components and advanced features, ensuring optimal process performance in a wide variety of production applications. It has a powerful range of grinding and polishing modes which can be set with the programmable digital control machine. Additionally, it also offers a patented zero-site adjustment technique, which further increases precision levels and accuracy. This wafer grinding, lapping and polishing tool is an excellent choice for production applications, particularly for materials that require a fine finish and precise results.
