We can assure you the finest quality job for any metal stamping process.
Edge rolling is a term used when a metal spinning craftsman takes a trimmed part and rolls the edge of the part to form a radius. Oftentimes, the piece is put on a lathe and a roller or a radiused tool is used to “roll” the edge of the metal to form a radius. The rolled edge actually builds strength onto the edge and helps make the part less likely to warp or oil can. In addition, if the part is being used where people come into contact with the part, it is a safe measure to prevent injuries due to a sharp edge.
Beading is very similar to edge rolling in that one form takes a trimmed metal piece and places a radius on the edge. Another form of a bead would be an impression into the metal around the part. For example, a customer may want a seal placed upon a part – the bead that forms an impression circumferentially around the part will allow a gasket or a rubber seal to set into the bead and can be mounted to the mating part to prevent leaking of substances. TMS uses, often times, a machine that is specifically designed to trim and place a bead on the part – this machine can trim, cut and place inward and outward beads. Beads, like edge rolling, can efficiently place strength into a part by simply rolling an edge. This is an inexpensive and brilliant way to build strength into a part without welding or further forming. It is an easy engineering technique to incorporate into a part.
Trimming is a term used when a part needs an edge smoothed out and the burrs removed. Oftentimes, a part is put either on a lathe or a trim/bead machine and a cutter will start to shear or shave off the edge to run true. A trimmed edge can be a straight off trim or the trim can be radiused or beveled to make the edge safe for handling. An edge is oftentimes trimmed before beading or edge rolling. The tool used to trim is called a cutter or an insert. These tools can be designed to apply the correct trim the customer desires whether it be a straight edge, a beveled edge or a radiused edge. A skilled metal spinner can trim an edge with a high degree of accuracy. In some instances, parts are spun to a near net dimension and the spinner then goes and does a final trim on the part to achieve the desired dimension. A skilled metal spinner can trim an edge to be within 1/64th of an inch – all by sight and feel. Depending on the part configuration, the part is checked with a Vernier caliper, a micrometer, a pi taped band and even a tape measure. Many times, tolerances are +/- 1/16”, but skilled spinners can work within +/- .005”, depending on part configuration and material used.
