Step 1 place the metal on a rubber block to stabilize the piece and leave the edge exposed or place it securely in a ring clamp.
Burnish sharp metal edge copper sheet.
Figure 2shows a cross sectional profile of the sheared edge of an aluminum blank note the burnished depth fractured depth burrs microcracks and other edge conditions.
This means this is not a step that will produce the exact same results every time.
For lack of better tools i had to use an angle grinder with a steel cutting blade and used a piece of angle iron to cut against to keep the cut straight.
In manufacturing practice sharp tools can mitigate burrs.
Here are photos of some of my work using 10 mil copper sheets.
The burnish zone is straight and has a smooth surface while the fracture zone is angled and has a rough surface.
You can also use a pair of scissors or a utility knife but the edges are very sharp so you will want to be careful.
I usually use a pair of snips to cut 10 mil.
Burnished finish is a type of finish applied on copper usually after fabrication of planters and other items.
It always looks different but always great.
This process will round the edge of the metal and create a groove in the point.
Reducing the damaging effects of fractures burnishing burrs and rollover improves subsequent forming processes.
The sharp edges can be smoothed and softened using simple tools such as sandpaper and metal files which can be found at hardware or home stores.
Sheet metal taking the sharp edge off i just cut some 16 gauge sheet metal today for shelves on my welder cart and was wondering what is the best easiest way to make the cut edge not so sharp.
R ub transferring is a great way to add a texture or an image to the tooling metal.
Examination of the edge surfaces of cut sheet metal will display differences between the burnish region and the fracture region.
The beveltools beveling machines are ergonomic making it easy to get them to the metal.
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 compact design of the beveltools concepts introduces unprecedented flexibility in rounding metal pipes and sheets.
As a result rounding small openings from a diameter of 5 8 16 mm becomes child s play.
Heat is applied to copper is order to generate the random discoloration of the metal.
The blanked edge condition can be improved by adjusting the punch and die clearance tolerance shaving the area of the defected blanked edge designing an appropriate contact profile of the tool and die and understanding the mechanical properties of the sheet metal used.
For example the image of a coin placed under the copper sheet can be transferred by rubbing or burnishing the metal over the coin with a rounded tool the pen cap works well here as well.
I have created metal atcs and metal collage cards with 10 mil copper sheet.
The sheared edge exhibits some distinctive characteristics.
Run the mounted point over the other sides to break those sharp.
