Rapid Prototyping for Custom Slip Rings
When designing electrical slip rings, electrical characteristics must seamlessly align with the mechanical needs of the machine. Available space, fastening positions, and cable routing all heavily impact the ability to integrate the component correctly.
Rapid prototyping via 3D printing helps us tackle these challenges in the early stages of development. Moving from a digital drawing to a physical model allows us to examine the proposed solution and identify potential improvements much sooner. For the machine builder, this means minimizing the risk of late-stage revisions and helping to keep the project’s time-to-market in check.
Verifying Clearances, Cable Routing, and Mounting Interfaces
A 3D-printed model makes the slip ring’s geometries and its interfaces with the machine directly observable. We can verify the space occupied by the body, the position of the flanges, and the accessibility of the fastening points, actively evaluating any potential interferences with surrounding components.
Cable exits also require special attention: the available space must accommodate the planned routing and respect the bending radii required by the actual cables being used. A physical mockup helps evaluate these aspects alongside the assembly sequence, making discussions between our technical department and the client’s team far more tangible and productive.
Anticipating Changes Before CNC Turning and Milling
Discovering an interference when a metal component has already been manufactured can lead to costly rework and project delays. 3D printing allows us to anticipate many geometric checks before committing valuable resources to the CNC turning and milling of the final parts.
However, it is important to note that the prototype has a specific purpose: to support shape and assembly verifications. A geometric mockup does not demonstrate the electrical performance, contact lifespan, or dielectric strength of the final slip ring. Furthermore, dimensional checks must always account for the precision limits of the printing process; final tolerances will always require dedicated quality controls.
The Celco R&D Workflow: From Model to On-Machine Fitting
In Celco’s research and development process, 3D printing goes hand-in-hand with the design of our custom slip rings. Starting from the CAD model, we create physical mockups that allow us to thoroughly discuss integration aspects before producing the final components.
These models can be shipped to clients for preliminary fitting tests—verifying physical compatibility and on-machine assembly. This allows the designer to check clearances in the real environment and flag any necessary modifications. The feedback collected becomes valuable guidance, allowing us to update the design and move forward with development on a much more solid foundation.
