B&M Machine Co. has been a precision machine shop in Belleville, New Jersey since 1947 — now in its third generation. We mill, turn, finish, and inspect brass, aluminum, stainless, and plastic parts under one roof, for customers who need precision and a finish that matches.

We're not the biggest shop, and we don't try to be everything to everyone. If your job needs tight tolerances and a surface finish that's actually to spec, we're the right shop. We run Haas and Mazak equipment, finish in-house, verify with CMM, and answer the phone.

Where We Come From

B&M Machine was founded in 1947, originally manufacturing fasteners. For our first 40 years we were almost exclusively an aerospace shop — making high-precision fasteners from exotic materials like Inconel, Waspaloy, and Hastelloy. That background shaped how we run every job: the attention to tolerance, the process discipline, the expectation that a part either meets spec or it doesn't ship.

Over the decades we grew into contract manufacturing for industrial, pharmaceutical, and custom hardware customers. The third generation of the Bing family runs the shop today, in the same Belleville facility, with modern Haas and Mazak equipment alongside the standards that haven't changed since 1947.

What We're Here to Do

Our mission is straightforward: be a high-value machine shop. That means creating value for our customers, value for our employees, and a company that's built to last.

For our customers

We deliver on what you specify — dimension, tolerance, finish, delivery — and we anticipate what you need before you have to ask. We treat customers as long-term partners, not transactions. Many of our relationships go back decades. We run your product line like it's our own, which means we're as invested in getting it right as you are.

For our employees

Safety first, always. We believe in fair pay, honest two-way communication, and a workplace where people are treated with dignity and respect. A shop that takes care of its people makes better parts.

For the long term

We're building a company that lasts — one that serves current customers well, develops the next generation of machinists, and is worth handing down. That means managing risk carefully, running lean and controlled processes, and never compromising quality for short-term gain.

Our Standards

The Team
