From a small workshop to a trusted name.
TOP Machining Inc. grew up in Silicon Valley — and grew fast, by treating every part as if our name depended on it. Because it does.
We started the way most great shops do — small, hands-on, and obsessed with getting it right. What began as a modest workshop has become one of the region’s most trusted precision CNC machine shops, serving the companies that build the future of aerospace, defense, medical, and semiconductor technology.
That growth didn’t come from cutting corners. It came from the opposite: refining our processes year after year, investing in multi-axis machining, lathes, welding, sheet metal, finishing, and full assembly, and holding ourselves to tolerances that leave no room for “close enough.” From a single prototype to ongoing production, we take care of the whole job — so our customers don’t have to worry about a thing.
It’s a simple philosophy, and it’s the reason we’ve earned a reputation this strong in such a short span of time. When the part matters, people come to us.
Quality is at the core of everything we make. Every component that leaves our facility meets or exceeds specification — no exceptions.
Our Mission
To deliver reliable, precision-engineered machining solutions that empower innovation across industries — through skilled craftsmanship, advanced technology, and a relentless focus on quality, communication, and continuous improvement.
