Used PETER WOLTERS AC 1400 #293825195 for sale

PETER WOLTERS AC 1400 is a wafer grinding, lapping and polishing equipment designed for the processing of various semiconductor materials and optical components such as silicon, gallium arsenide, and sapphire. The system is capable of grinding, lapping and polishing a wide range of materials from the softest material to the hardest with a maximum diameter of 140 mm. AC 1400 has a flat table design with two loading and unloading areas and up to eight grinding, lapping and polishing zones, making it possible to process a large number of substrates simultaneously. The unit is equipped with a stepper-motor driven spindle, which is of high precision, to ensure a high throughput rate, good surface finish and high accuracy of the product. The spindle can rotate at up to 25000 RPM. A up to three-axes traversing unit is mounted on the rear side of the table for the optimization of the grinding and polishing process. The grinding, lapping and polishing process can be performed with a wide selection of lapping and polishing compounds, pure diamond suspensions and abrasives including diamond suspensions with ferrite matrix. PETER WOLTERS AC 1400 is equipped with a dust and extraction machine to minimize hazardous particle emissions. The tool's operation parameters can be adjusted and the process data are controlled and monitored during grinding, lapping and polishing process by a digital control unit with a touch screen. Large numbers of different working parameters can be stored in the control unit. AC 1400 wafer grinding, lapping and polishing asset is a reliable and cost effective solution for the processing of a large number of semiconductor materials and optical components such as silicon, gallium arsenide and sapphire. The model is suitable for a wide range of materials, delivers good surface finish and high accuracy, and ensures an easily adjustable and monitorable process.
