Rounding Sheet Metal Edges

Step 3 weld all seams.

Rounding sheet metal edges.

Rounding edges with minium radius 2 mm is a necessity for good adhesion of coating or paint to protect against corrosion. Only edge round when necessary. Edge rounding is indispensable in order to achieve a high quality final part. Deburring and edge rounding of sheet metal is one of our main fields.

In addition to that it also reduces the complete and overall risk of rust corrosion and the chipping off of the coat that it has. One of the main reasons why the process of sheet metal edge rounding is carried is to try and eliminate any left on the sheet metal parts. Step 1 is to design the corners like shown in above image. Step 2 is to tack weld the cornerfill into place.

Standards have been derived from these findings e g. Rounding off sharp edges with radius cutters good and accurate rounding of steel constructions according to en 1090 iso 12944 iso 8501 or imo pspc is becoming more and more important in the metal working industry. This helps to ensure that the downstream process functions in a much smoother way. Learn some basic metal working techniques on how to make perfect round corners and radius edges.

Most customers require edge rounding or at least edge breaking of the edges of metal workpieces. One thing that is important to note is that we do not have some kind of burs on sheet metals. Otherwise the staff members in manual assembly processes and end users may injure their hands. Rounding the edges of the sheet metal apparently increases the surface area of the products giving you more room in terms of powder coating it anodizing it metal plating it and the like.

Rounded edges reduce the risk of injury and optimize downstream processing whether they are being welded or coated. Step 4 grind flush. Nevertheless numerous practical applications have shown that good paint adhesion is often achieved with a rounding of just 0 5 mm on the sheet metal edge. For steel construction which require a radii of 2 0 mm and more on the edges for certain components.

Therefore they must be extremely careful when manoeuvring the workpieces so they cannot work quickly. Loeser is building machines for deburring edge rounding grinding and polishing of flat material like fine stamped parts or fine blanking parts as well as profiles. However it is important to consider which degree of edge rounding is necessary for your business purposes depending on corrosion protection requirements.
