TOPS – Provide You With the Best CNC Bending Services
Below are our various approaches toward obtaining accurate and reproducible bends on sheet metal. Every process, such as Air Bending and Bottoming, rotary bending, and Wipe Bending, has its features, where angle precision, surface delicateness, and material management are some of the discriminating features. TOPS processes allow manufacturers to determine the most effective type of bending for quality and yield in production.
| CNC Bending Process | Description/Details |
| Air Bending: This method uses three points of contact, and part of the material is designed to penetrate the punch and die without actually touching them. It is very, very flexible, and you can get different angles using the same toolset. | . |
| Bottoming (Coining): While bottoming, the material is completely formed to the die resulting in an accurate bend angle. This process provides better precision but utilizes more force than the previous process. |  |
| Rotary Bending: Unlike a razor die that forms the bend, a rotary die produces the bend in a superior way that relatively reduces the issue of material handling. This method causes less marking and is suitable for sensitive or primed or pre-coated surfaces as it is. |  |
| Wipe Bending: A wiping die presses the sheet metal to a fixed point to produce the bend. The rotary bending process is often used when making bent parts on thin materials that need precise edges. |  |
| V-Bending It can accommodate the different bend angles. It is mainly because of its V-shaped punches and dies. Besides, this, it is advisable to use it for moderate bending activities, |  |
| Roll Bending: A sequence of rollers is applied to gradually shape the channel member, as required for a large radius curve. This method is mostly employed for cylindrical shapes or curves in products. |  |
| U-Bending: This technique forms U-shaped bends and is used for complicated essential shapes. Besides that, they are used in car production as well as in the production of home appliances. | . |
| Step Bending (Bump Bending): This process entails creating a small number of bends with a view of a large radius curve. It is used for gradually forming curves when using genuinely curved tools might not be practical. |  |
Design Guide for CNC Bending
Our “Design Guide for CNC Bending” contains important information about the necessary bending procedures on CNC materials, i.e. aluminum and stainless steel. It covers fundamental features like bend radius, angle, thickness tolerance, and post-bend treatment, this guide guarantees the structural datum, preciseness, and aesthetic external appearance in CNC bend projects.
Design Element | Guidelines/Values |
Material Selection | Use materials like aluminum and stainless steel with good bending characteristics. |
Bend Radius | Maintain a radius of 1-2 times the material thickness to avoid cracking. |
Bend Angle | Specify angles precisely (e.g., 30°, 45°, 90°) and ensure they meet tolerances. |
Thickness Tolerance | Aim for a tolerance of ±0.01 mm (±0.0005 in) for precision. |
Minimum Bend Length | Keep it at least 2-3 times the material thickness to prevent distortion. |
Stress Concentration | Design gradual transitions to avoid stress points that could lead to failures. |
Clearance Between Bends | Allow enough space between bends to prevent interference. |
Orientation of Bends | Optimize bend orientation for tooling and material flow; avoid sharp bends. |
Surface Finish | Specify smoother finishes for better results and tool longevity. |
Post-Bending Treatment | Plan for treatments like annealing or coating to improve material properties. |
What is CNC Bending?
Computer Numerical Control Bending, or CNC Bending, is the craft of bending material like metal, sheet metal, or even pipes with the help of computers. Depending on the design, engineers enter the details of the part into a computer, and the CNC-controlled bending machine uses force to conform the material to the desired shape.
- Automation in the CNC bending process leads to accuracy in the bending process of the final product.
- It is fast and effective for producing bent shapes for difficult spots and achieving various angles at once.
- Ideal for creating parts needed by car makers, aircraft builders, and makers of medical applications.
How CNC Bending Works?
- Planning: When bending, we make sure we have read through the design specifications carefully to avoid mistakes.
- Set Up the Machine: The CNC bending machine is programmed according to the client’s instructions to deliver the project by making precise bends.
- Bending: The machine then molds the material in the required angles and sizes as dictated by the programmed sequence hence successiveness.
- Check Quality: Every part is inspected after bending to ensure maximum standards are achieved.
CNC bending is one service that you should always turn to us for.
