Used OKUMA GP-35N #9093312 for sale

OKUMA GP-35N is a wafer grinding, lapping and polishing equipment designed to meet the stringent requirements of semiconductor, optic, and MEMS device production applications. The system employs robust grinding accessories and precision-engineered components for cost-effective and highly reproducible results. The mainframe of GP-35N is CNC-controlled, and can be optimized by the user via an intuitive touch-screen display. The mainframe facilitates precise grinding motion control, including compensating for oscillations in pressure, temperature, and the grinding material itself. Its cast iron base ensures a vibration-free grinding experience, and a high-quality VFD-controlled motor further ensures that the grinding motion is consistent and efficient. OKUMA GP-35N includes an adjustable precision loading table, which provides efficient wafer compatibility and exchanges. Its wafer conveyance unit features easy-load clamps and improves accuracy. The mainframe features an intuitive fixture setup, and allows up to fourteen different grinding motions to be programmed and stored as required. The machine is designed to grind large wafers of up to 300 mm diameter at a range of angles. Its rotating wafer holder is managed by an advanced high-resolution servo drive, and the belt grinds wafers to any angle. The granite tables are adjustable to a range of angle settings to ensure accuracy and uniformity. GP-35N can be used with a variety of grinding materials such as Al2O3, C11N, TCT, BeSiC, and MO. The grinding accessories include clamps, diamond pads, platen, polishing batch, etc. The optional vacuum wafer carrier ensures improved debris removal. The interior cabinet features easy-to-remove access panels, air monitoring, and advanced filtration. In addition, OKUMA GP-35N is designed for ease-of-use and efficient maintenance. The grinding table is modular, allowing for easy components replacement, and the mainframe can be easily accessed by maintenance personnel. All tool components are manufactured for long-term use, and the asset features automated diagnostic checks to ensure reliable repeatability and optimal performance.
