With the aid of a straight edge and a sharp knife score both sides of the aluminium sheet.
Folding sheet metal edge to eliminate sharpness.
It is important to make sure that the sheet is properly pushed onto the wipe die.
Step 1 secure the sheet metal to prevent slipping.
The slack between the wipe die and the punch plays an important role in getting a good result.
Sheet metal s edges particularly with regard to the part after manufacture.
Hems are most often used to remove a sharp untreated edge and make it safe for handling.
Sheet aluminium can be cut without the need for a guillotine or tin snips which tend to deform the metal.
Figure 3 a sheared sheet metal edge has several attributes that make it sharp.
Edge bending operations are commonly used in industrial sheet metal processing and involve bending a section of the metal that is small relative to the part.
The edges may appear flat but shearing dies leave burrs.
This process will round the edge of the metal and create a groove in the point.
As a result the wipe die also determines the bend s inner radius.
Use a die grinder with the mounted point and simply run the point over the edge of the sheet metal.
Looking to dull edges on sheet metal for safer fabrication.
This technique allows you to dull the edge in one run instead of breaking the edge on the top and.
Edge bending is used to eliminate sharp edges.
The edges may appear flat but shearing dies leave burrs.
These sections are located at the edges.
This weakens the aluminium and creates a fracture line.
Wipe bending or edge bending is another way to bend sheet metal edges.
Many products use sheared sheet metal yet only one standard ul 1439 addresses the issue of sheet metal sharpness directly.
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.
Step 3 repeat.
Secure the sheet metal to prevent slipping.
