8 Principles of Centerless Grinding

Dec 08, 2016 · Roundness depends on angles. However, with a wheel width of 6" (152.4 mm) or 8" (203.2 mm), that same angle may generate too much pressure toward the grinding wheel and cause chatter. Changing the angle to 20º or 25º will reduce the pressure and eliminate the chatter on the part.

How to Weld Aluminum (with Pictures) - wikiHow

Mar 29, 2019 · Clean the aluminum. Over time, aluminum forms a thin coat of aluminum oxide on its exterior, which melts at a much higher temperature than aluminum. So, before welding any piece of aluminum, you have to clean away the aluminum oxide. Do this mechanically by wire-brushing, grinding, or filing away the oxides.
