Upload a STEP file. Our software checks whether it fits the cell, flags anything that needs changing, and turns accepted designs into a quote and machining plan. We cut it in San Francisco, with rapid turnaround when the part fits and capacity allows.

Drop a STEP file. We read the geometry, find the holes, pockets, and profiles, and check whether the part can be held and cut in our cell. You get the awkward questions before metal meets spindle.

If it fits, our software picks the stock, setup, and tools, simulates the cut, and prices the job. If it doesn’t, we show you the feature causing trouble and what to change. “No” should still be useful.

it here

Accepted jobs go onto our own CNC in San Francisco. We run production and inspection ourselves while we teach the cell to load, cut, and check more on its own. Shorter lead times are the point.

A SMALL BOX, ON PURPOSE

What fits the cell

We don’t pretend to machine everything. We standardize the machine, material, stock, tools, and workholding so the parts we do accept move fast and come out right.

Fewer materials. Fewer variables. Faster parts.

Attach a PDF with your STEP. We read the tolerance and finish callouts, then plan machining and inspection around them.

WHY BUILD A VERY PICKY MACHINE SHOP?

Fast by design

To the people building hardware,

Prototyping moves quickly until a machined part enters the chat. Then comes the RFQ inbox, the setup fee, the lead time, and the familiar request to explain the whole thing again.

Traditional shops are built for repeat production. Hardware teams revise, test, and revise again. Every version creates new quoting, programming, setup, and inspection work. Small orders get expensive, slow, or politely ignored.

So we chose a smaller problem: rapid parts inside a well-defined machining envelope. We standardize the machine, stock, tools, and workholding. Software handles DFM, quoting, and programming. We own the machine, so quality and lead time are ours to answer for.

Between us, we’ve spent years writing software, building robots, and making physical things. We own the code and we run the shop. It keeps the feedback loop short, and your prototype lead time shorter.

Less waiting. More testing.
