In curling the initial edge is rolled into the formed circle whereas in the tear shaped hem the initial edge is still exposed.
Bending sheet metal with a lateral curl.
Curling is the process of forming a circular ring at the edge of the metal sheet to make it safer for handling.
Bends specified as angles may be toleranced at plus or minus one half degree at a location adjacent to the bends.
Sheet metal bending bending of sheet metal is a common and vital process in manufacturing industry.
Curling is different than a tear drop hem because in a curl the edge finishes inside itself where a hem leaves the initial edge exposed.
In low carbon steel sheet metal the minimum radius of a bend should be one half the material thickness or 0 80 mm 0 03 inch whichever is larger.
Similar to other metal forming processes bending changes the shape of the work piece while the volume of material will remain the.
This set consists of two tool sets and two strokes to.
Avoid large sheet metal parts with small bent flanges.
Sheet metal bending is the plastic deformation of the work over an axis creating a change in the part s geometry.

Market leader for sheet metal fabrication solutions and metalworking machinery such as sheet metal shear press brake and hydraulic press.
Avoid large sheet metal parts with small bent flanges.
The curled edge provides strength to the edge and makes it safe for handling.
Curling means forming an edge of circular cross section along a sheet or at the end of shell or tube.
There is a difference between a curled edge and a tear shaped hem.
Bends specified as angles may be tolerance at plus or minus one half degree at a location adjacent to the bends.
In low carbon steel sheet metal the minimum radius of a bend should be one half the material thickness or 0 80 mm 0 03 inch whichever is larger.
The whole structure of hydraulic cnc press brake tandem press brake 1.
In sheet metal fabrication parts are formed from metal sheets by punching cutting stamping and bending.
The most defined curls are made with our cl3 design.
