Precision Parts Smaller Than a Paperclip

At first glance, those colorful paperclips steal the show. That's precisely why we used them to stage this photo. The actual components are so incredibly small, you'd probably scroll right past them without something to show the scale.

But make no mistake: these aren't just tiny parts. They're custom CNC-machined from stainless steel, threaded with M2 internal features, and are now integral to a much bigger system developed by one of our customers.

Small = Critical: The Unseen Demands of Micro-Scale Engineering

Our customer came to us with a high-stakes challenge: produce a batch of stainless steel parts, each smaller than a paperclip, with M2 threading and high dimensional accuracy for a prototype.

• ➡️ Ultra-small footprint: machined from stainless steel

• ➡️ M2 threads: Extremely fine and difficult to cut cleanly

• ➡️ Fully Inspected: With uncompromising quality assurance.

These parts may look playful next to office supplies, but their purpose is intensely serious. Once assembled, they would sit at the heart of a test platform for a next-generation autonomous system, where failure is not an option.

Why Projects Like This Demand Not Just Precision, but Agile Thinking

When you're working with components smaller than a paperclip, like these custom steel parts, every micron counts. Every feature is measurable in tolerances that sound minor but carry profound implications for system performance.

At this scale, especially in industries like aerospace, robotics, and automation, every technical consideration for a manufacturing engineer magnifies exponentially:

• Tool deflection must be anticipated and meticulously compensated for.

• Chip evacuation and cooling must be considered to avoid burrs or deformities

• Measuring and inspecting M2 threads on such small parts requires specialized gauges

• Thread quality must be visually and physically verified across the entire batch to prevent stripping or seizing.

There’s simply no margin for 'good enough.' Unlike larger components where slight imperfections might be smoothed out downstream, here, you either hit tolerance or you start over.

At Rototip, we love a good challenge

Who knows, maybe these tiny components will be a part of the next autonomous technology breakthrough.

At Rototip, we don't just welcome a good challenge; we thrive on them. We love jobs like this not only because they're technically demanding but also because they remind us that the biggest leaps in innovation rarely come in large crates. Sometimes, it’s a part the size of your thumbnail that carries the greatest responsibility and enables the most revolutionary designs.

If you're an engineer, designer, or R&D specialist in sourcing custom CNC-machined parts, especially small components requiring unforgiving tolerances, Rototip is here to help.
