FAQs

Sensor & Control Housings FAQs

Have specific technical queries regarding your robotic Sensor & Control Housings? Reach our engineering team at info@robotcncparts.com.

What is the minimum fin thickness you can machine for heat sinks?
We generally machine cooling fins down to 0.5mm thickness, depending on the height-to-width aspect ratio. For deep, thin fins, we use specialized high-speed machining strategies to prevent vibration and tool chatter, ensuring efficient thermal dissipation without deformation.
How do you ensure leak-proof sealing for outdoor controller enclosures?
While the design dictates the IP rating, we guarantee the critical manufacturing specs. We focus on the flatness of the sealing face (typically <0.05mm) and the surface finish of O-ring grooves (Ra 0.4-1.6μm) to ensure a perfect mate that prevents water or dust ingress.
Can you provide conductive finishes for EMI shielding?
Yes. Standard anodizing is insulating, so for parts requiring grounding or EMI shielding, we offer Alodine (Chromate Conversion Coating). We can also perform selective masking, where we anodize the exterior for durability while keeping internal mounting points bare and conductive.
How do you prevent reflection interference on camera and LiDAR?
We understand that stray light affects sensor accuracy. We provide Matte Black Anodizing combined with bead blasting to create a non-reflective, light-absorbing surface ideal for optical and vision systems.
How do you control deformation in thin-walled sensor brackets?
Thin-walled aluminum parts are prone to warping. We mitigate this by using a multi-stage machining process with stress-relief annealing if necessary. We also optimize clamping pressure and cutting paths to maintain strict concentricity and alignment for your sensors.
Do you inspect thread quality for connector holders?
Absolutely. Connector ports and mounting holes often use fine threads that are easily damaged. We verify all threaded features with Go/No-Go gauges after plating to ensure your connectors and cable glands install smoothly without seizing.
