Removing Sharp Edges in one Run
This short video demonstrates a time saving technique for dulling edges on sheet metal. There are numerous ways to smooth sharp edges, but we find this the easiest. This method finishes the top and bottom edges of the sheet metal in one pass instead of smoothing each edge separately.
Tim Borges, North American Distribution Sales Manager, demonstrates how to smooth the edge of stainless steel sheet metal by using a W222 mounted point.
Products used: W222 Mounted Point - A54GFX-NC (part no. 339873)
Step 1. – Secure the sheet metal to prevent slipping.
Step 2. – Use a die grinder with the mounted point and simply run the point over the edge of the sheet metal.
Finishing More Complicated Edges
New, cut, punched, machined, or molded metal will have sharp edges. For safety, function, or aesthetic reasons, deburring and smoothing is often required. The edge you are looking to finish isn't always a straight line that's easy to access. When deburring or edge breaking a punched hole, laser cut, or an intricate part, a W222 shape might not be the best point for your application. A smaller tapered point could be more appropriate. We manufacture cotton fiber points in many sizes and have a shape chart with dimensions and rpms available for download here.
A54GFX is the grit and bond of the cotton fiber mounted point used in this video. Many different grit and bond combinations are available to suit heavy to light metal removal on stainless steel, aluminum, mild steel, brass, titanium, and more.
