Jiri Praus has created an Arduino-powered CNC machine that can precisely bend brass wire, and even features a set of rollers to help straighten the wire before any precision bends are made. This innovative machine is a game-changer for hobbyists and professionals alike who work with wire sculptures and need consistent, precise bends. Watch the demonstration videos below to see a spiral spring being created as well as a systematic range of bends to create precise shapes with wire measuring 1mm and less in diameter.
Innovative Design and Functionality
The machine’s design is both practical and innovative. It uses an Arduino microcontroller to manage the bending process, ensuring high precision and repeatability. The inclusion of rollers to straighten the wire before bending is a thoughtful addition, as it ensures that the wire is perfectly aligned before any bends are made. This feature is particularly useful for creating intricate designs where even the slightest deviation can result in a flawed piece.
“I build sculptures out of brass wires and since I hate repeating creating same part over and over again I decided to build a wire bending CNC machine that would do the job for me. So far it is still an early prototype but looks promising! The goal is to build a machine that has most of the parts 3D printer or easy to get so everybody can build it at home,” says Jiri Praus.
Applications and Future Developments
The potential applications for this wire bending machine are vast. From creating custom springs and intricate wire sculptures to producing components for electronics and mechanical devices, the possibilities are endless. The machine’s ability to handle wire with a diameter of 1mm or less makes it suitable for delicate and detailed work, which is often required in artistic and technical fields.
Jiri’s vision for the machine is to make it accessible to everyone. By using parts that are commonly found in 3D printers and other easily obtainable components, he aims to create a machine that can be built at home by anyone with basic technical skills. This democratization of technology is in line with the maker movement, which encourages individuals to create and innovate using readily available resources.
For those interested in building their own wire bending machine, Jiri has made the full project details available on the Hackaday website. The site includes comprehensive instructions, a list of required materials, and the necessary code and resources, which are also available via GitHub. This open-source approach not only fosters a community of makers but also allows for continuous improvement and customization of the machine.
