When people think of CNC machining, they often picture massive engine blocks or large aerospace panels. However, the true heartbeat of any complex machine—whether it is a robotic arm, an optical testing device, or a custom automation line—lies in its smallest components.
At CNC Rapid, we know that small parts require massive attention to detail. We specialize in manufacturing Small CNC Machined Parts, delivering custom brackets, flanges, and precision hardware that fit together perfectly on your assembly line.
Let’s explore some of our recent high-precision small component projects.
The Challenge of Machining Small, Complex Hardware
The part shown above may fit in the palm of your hand, but it is packed with complex features. Manufacturing custom aluminum brackets and mounting blocks of this size requires extreme precision.
- Tight Tolerances: When small parts are used to connect larger assemblies, even a 0.02mm error can cause misalignment. We maintain strict tolerances to ensure a perfect fit.
- Intricate Features: Notice the stepped rectangular cutout and the perfectly aligned mounting holes. We use small-diameter micro-end mills and rigid CNC setups to cut these fine details without breaking tools or damaging the part.
- Precise Threading: Tapping small holes in aluminum requires precise speed and feed control to ensure the threads are strong and clean for your screws.
High-Mix, Low-Volume Manufacturing Ecosystem
Engineering projects rarely just need one type of part; they need a whole ecosystem of custom hardware. In the collection of parts shown above, you can actually spot the slotted block from the previous photo alongside its mating components!
Surrounding it are deep-grooved heat-sink blocks, tiny U-shaped clevis brackets, and other custom connectors.
- Agile Production: At CNC Rapid, we excel at high-mix, low-volume manufacturing. Whether you need 5 pieces of a unique bracket for a prototype, or 500 sets of a complete hardware kit, we can handle it efficiently.
- Burr-Free Guarantee: The sharp edges on small parts can easily cut wires or prevent proper assembly. All of our parts undergo careful deburring and inspection to ensure smooth, safe, and professional “As-Machined” edges.
Custom Flanges & Rotational Components
Beyond square brackets, many of the Small CNC Machined Parts we produce are designed for motion control. The circular component above is an excellent example of a custom mounting flange or robotic joint interface.
For rotational parts, the most critical requirement is Concentricity (making sure all the circles share the exact same center point).
- Perfect Alignment: The central hub and the outer ring of mounting holes must be perfectly aligned. We machine these features in a single CNC setup whenever possible to eliminate positioning errors.
- Weight Reduction: By carefully milling out specific areas of the aluminum disk, we reduce the overall weight of the part while maintaining its structural strength—a crucial factor for drones and robotic applications.
