Di-Acro Bending Brake

Our Di-Acro Finger Brake

A brake is a metalworking machine that allows the bending of sheet metal. A brake consists of a flat surface on which the metal is placed, and a clamping bar that will come down and hold the material during a bend. On the Idea Shop's finger brake, also known as a Box-and-Pan brake, the clamping bar includes removable blocks that may be removed or rearranged to permit bending of restricted areas of a piece of sheet metal or of already partially formed pieces.

Angle Adjust

To adjust Brake for bending clearance, raise folding blade 90 degrees, insert material between edges of folding blade and leading edge of fingers (for heavy material, clearance should be twice the thickness, less for lighter gauge or if sharper bend is desired). Adjust finger mount bar by turning finger mount bar adjustment screws. To adjust clamping pressure insert material under fingers and turn material adjustment screws until material is held securely when fingers are lowered. To adjust degree of bend, set angle stops located on both ends of folding blade for desired degree of bend.

Reverse Bends

Safety First

Remove five angle support bar bolts and support bar and adjust Brake as above. NOTE: 16 GAUGE CAPACITY (with support bar in place)

MINIMUM LENGTH OF BEND WHEN FORMING A REVERSE BEND = 1/4


NOTE: Di-Acro Brakes are rated for 1" minimum flange when bending full capacity. Caution should be used if necessary to bend heavier gauge material in short widths.

Safety First

One thing you should watch out for in this machine is the moving parts. If you get a finger stuck in there, the finger brake might break your finger.

Wear goggles whenever you work with metal. Aluminum chips in the eyes are no joke. Magnets will not work to get them out.
