About B&Z Manufacturing

Since 1960, B&Z Manufacturing has been machining ultra-precision components for San Francisco Bay Area companies within California, such as Agilent Technologies, Hewlett-Packard, Honeywell-Measurex, and others. We specialize in multi-axis milling and turning and our facility has been granted ISO 9001:2015 certification by DQS Inc. B&Z is a clean, modern, temperature-controlled, 16,000 square foot high-tech manufacturing facility. Through many years of experience, our quality and "just-in-time" delivery have gained us recognition in the electronic, aerospace, medical, military, and computer industries.

We added a new facility in Nashville, Arkansas in 2006. This new facility is currently 6,000 square feet and growing fast. As an alternative to sending work overseas, B&Z has chosen to maintain its quality workmanship by opening up another facility in a less expensive part of the United States.

Remaining high-tech after all these years is our key to success. Our capabilities include 4 and 5 axis machines, high production pallet changers, internal electronic probing on machines, 3 Zeiss CMMs to ensure repeatable quality, and communication convenience with the ability to start with purchase orders, program/run-parts, and invoice from electronic files via the internet.
