We have a possibility to offer the tube bending tooling from simple set for easy-bended tubes up to complicated solutions with the several levels of bending die (multi-stack), one- or multi-ball mandrels, special surfaces for short straight part and tight clamping, special profiled tooling etc.Īll solutions are unique and we are offering the ability to project the tooling based on your necessities and request. Our specialization is the tooling for draw tube bending process with the forming of tube radius according to the size of bending die with the use of mandrel tube and pipe bending machinery. Without drawings for all machines we can offer mandrels and wiper-dies. with the great experience for leading Italian tube bending machines manufacturers. We offer tube bending tools as complete kits* or rechangeable separate tools for CNC hydraulic and electric tube and pipe bending machines of main worldwide manufacturers from Italy, UK, USA, Germany, Taiwan etc. Tabs must be at least 2 times the material’s thickness or 0.126”, whichever is greater, and can be no longer than 5 times its width.Tube bending tools for CNC bending machines Notches must be at least the material’s thickness or 0.04”, whichever is greater, and can be no longer than 5 times its width. Recommended corner radius for notches should be 0.5 * t. Notch width should not be narrower than 1.5 * t.

Tabs must have a minimum distance from each other of 1mm or the material’s thickness, whichever is greater. For bends, notches must be at least 3 times the material’s thickness plus the bend radius. Notches must be at least 3.175mm away from each other.

Notching is a low-cost process, particularly for its low tooling costs with a small range of standard punches. To avoid such condition notch should be placed at appropriate distance from bend with respect to sheet thickness. In case, distance between the notches to bend is very small then distortion of sheet metal may take place. Notching is a shearing operation that removes a section from the outer edge of the metal strip or part.
