Used PETER WOLTERS AC 320 #9232335 for sale

PETER WOLTERS AC 320 wafer grinding, lapping & polishing machine is specifically designed for mass production of spherically shaped components. The machine is capable of processing a variety of materials, including metal, ceramic, quartz, and semiconductors. It uses a combination of abrasive compounds, diamond lap plates, lapping films, and a unique polishing media to provide a superior finish. The machine consists of a modular spindle support frame, a fixed double-sided grinding wheel, a floating-dresser grinding wheel, a movable polishing wheel, an auto feeder, and a manipulator arm for controlling the grinding and polishing spindles. The spindle support frame is equipped with a variable speed drive that allows for up to three angular motions at constant rotational positions and adjustable pressures. The variable speed drive is used to control the grind depth, the feed rate and the abrasive rate. The grinding wheel is adjustable for either cylindrical grinding or flat grinding. The diamond lap plates are also adjustable according to the material being processed and the required grit size. With the adjustable tank and feeding lines, the lapping films can be recycled and reused up to three times. The polishing wheel uses a unique slurry media that is abrasive-free, which contributes to a fine surface finish. After the wafer is pressed against the lap plate with the polishing wheel, the slurry media captures the diamond particles and removes them from the surface. The operation of AC 320 wafer grinding, lapping & polishing machine is very simple. The operator just needs to select the feed rate, the grinding wheel speed, the abrasive rate and the feed rate of the polishing wheel. The machine then operates automatically to achieve a highly precise finish with minimal effort. The system is designed to be easy to use and its use reduces the cost of production and shortens the production time.
