As a result the wipe die also determines the bend s inner radius.
How to fold sheet metal edges.
Position the first fold such that it will enter the slot when the bend is complete.
Not the sheet itself.
The sheet metal is place between the two working surfaces of the folding bars and placed in a vice.
During seaming two sheet metal parts or two edges of the same sheet metal are joined in an interlocking manner.
It is important to make sure that the sheet is properly pushed onto the wipe die.
Make a slot along one edge of your folder to accommodate the first bend.
This process will round the edge of the metal and create a groove in the point.
Rough sharp edges can be a safety issue and are more difficult to remove once the sheet metal is folded to a 3d shape.
Step 3 repeat.
This is done by simultaneously folding or pressing the prepared and fitted edges.
Before folding sheet metal it is good practice to smooth all edges using a hand file followed by emery cloth.
Wipe bending or edge bending is another way to bend sheet metal edges.
When folding edges see first photo it is the edge that is placed in the bender.
Step 2 use your die grinder with a mounted point we like shape w222 and simply run the point over the edge of the sheet metal.
The slack between the wipe die and the punch plays an important role in getting a good result.
Step 1 secure the sheet metal to prevent slipping.
