Used DISCO DAG 810 #9394642 for sale

DISCO DAG 810 is a high-performance wafer grinding, lapping and polishing equipment. The system is designed to grind, lap and polish components of precise geometries and fine surface textures in semiconductor and other hard materials. DISCO DAG810 features a precision ceramic disk grinding plate, dual spindle grinding and lapping plate and a precision polishing plate to provide precise processing of various components. The grinding plate is made from a high-precision ceramic disk with an exact concentricity within 0.5 microns and a flatness within 1 micron. The dual spindle grinding and lapping plate are powered by two independent spindles for more efficient processing. A vacuum chuck is employed to secure the workpiece during grinding and lapping and is designed to maintain the flatness of the workpiece up to 0.15 microns. The precision polishing plate is constructed of a single pre-polished surface, allowing for high polishing quality with fewer parameters to consider, as well as an improved polishing performace with minimum noise and dust. The polishing head is powered by a DC motor, providing a configurable speed range of 0-2500 RPM. The end effector is pneumatically actuated and utilizes a polishing film to provide an accurate and smooth finish. A high-force pneumatically actuated polishing head is also included, providing a strong pressure that results in an increased polishing area per time unit for more efficient processing. The unit is designed for high-precision machining and polishing of hard materials and features a precision focus controller that provides precise spindle speed and feedrate control. The controller also features an automatic position and rate control for optimal wafer positioning and operation. Finally, DAG 810's air machine is designed for high-precision air bearing control, ensuring high accuracy processing and eliminating settling time. DAG810's advanced features provide manufacturers with an efficient and reliable wafer grinding, lapping and polishing tool.
