About
A small shop that takes hard parts.
Machining complex components in Livermore, California since 2010.
Who we are
Decades of machining, deliberately small.
SP Manufacturing operates in a market where complex parts have to arrive on time, to print, and at a price that still makes sense. As supply chains shifted overseas chasing labor cost, we went the other direction — toward capability. Fewer machines, better machines, and enough process engineering to actually use them.
That's the whole strategy. We can't beat an offshore shop on a simple turned part and we don't try. What we can do is take the part that's been quoted three times and rejected twice, and make it correctly.
The shop is owner-operated. When you call, you get someone who has run the machine, written the program, and will be accountable for the part.
About the name. The SP stands for Swiss Precision — the name we machined under from 2010 until we incorporated as SP Manufacturing Inc. Same shop, same people, same phone number. We kept the initials because the standard they were chosen for hasn't changed.
Our mission
To produce the highest quality precision machined components in a consistent and cost effective manner, according to customer deadlines.
Written in 2010. Still the standard we're measured against.
How we work
What being engineering-led actually means.
Plenty of shops say it. Here's what it looks like in practice on our floor.
We write our own post processors
The software that turns a toolpath into machine code is built and maintained in-house for our specific machines — so the code that runs is code we understand, not a generic template with the corners knocked off.
We build our own tooling software
Tool data management, program checking, magazine tracking and machine monitoring are tools we wrote because the off-the-shelf versions weren't good enough. They run our shop every day.
We watch both machines live
Machine state, utilisation and cycle data are captured continuously. Scheduling decisions and delivery dates come from real numbers, not from a guess about how the week is going.
We simulate before we cut
Programs are verified against the model — including collision checking with the real machine and workholding modelled — before a tool moves.
It went further than we planned. The tools we built to run this shop — post processors, NC program checking, tool presetting and magazine sync, machine monitoring, inspection reporting — turned out to be things other shops wanted too. They are now sold as products through our software arm, SP Tooling.
We mention it because it explains something about how we work. Every one of those tools exists because a real part on this floor needed a problem solved, and buying a solution wasn't an option. That's the same instinct we bring to your part.
Where we are
Livermore, California.
7653 Hawthorne Ave, in the Livermore/Tri-Valley area, an easy drive from the East Bay, Silicon Valley, Tracy and the 580 corridor.
Local customers are welcome to come look at the shop and the machines. If you're going to trust a supplier with a part that matters, it's reasonable to want to see where it's getting made.
Made in USA — everything we ship is machined here.
