CNC, Weldments & Casting

As an ISO 9001:2015 certified machine shop, OneMonroe combines high–end equipment along with experienced, skilled and dedicated toolmakers to offer superior advanced CNC machining to our customers. OneMonroe has generations of experience in precision CNC machining. We can provide materials, or use customer provided castings, weldments, bar stock, etc.

OneMonroe is capable of manufacturing almost any type details to customer supplied designs and specifications. We stock a wide variety of materials, and are well equipped with CNC machines, fixtures, tooling and inspection equipment. OneMonroe has assembled a comprehensive network of suppliers for processes such as laser and waterjet cutting, heat treatments, and plating. They expand and complete our capabilities. Quality is continuously monitored, competitive bidding keeps prices lean.

Volume

A combination of CNC machining centers and manual machine tools enable us to handle individual details and prototypes, through production volumes of parts. An inventory of quick set-up fixture components, thousands of tools and holders and offline programming provide flexibility and speed in processing work.

We are expert in the design & build of production work-holding fixtures for CNC machining centers. For high volume production OneMonroe combines CNC’s with “Pallet Changers”, production fixtures and 2 or 3 shift operations. We are extremely agile in this regard.

Weldments

OneMonroe operates a fully equipped in-house weld shop staffed by two certified welders with extensive experience in MIG and TIG welding across a variety of metals including aluminum, stainless steel, and carbon steel. This integrated welding capability allows us to support complex assemblies, structural fabrication, and welded subcomponents as part of your CNC machined parts. Whether it’s adding weldments to a machined frame, fabricating brackets, or finishing off a custom fixture, our welding team ensures precision, strength, and consistency — all under one roof.

Castings

OneMonroe offers end-to-end machining solutions starting with high-quality raw material inputs. We can source and machine a wide range of castings, forgings, and blanks produced through waterjet or laser cutting. Our team brings deep expertise in qualifying these inputs—whether aluminum castings, stainless steel forgings, or custom plate blanks—to ensure dimensional accuracy, structural integrity, and machinability.

By thoroughly vetting and preparing raw components such as weldments, near-net cast forms, and flame-cut blanks, we help maximize material yield and minimize scrap, ensuring that the CNC machining process results in consistently high-quality finished parts. This capability is ideal for customers requiring complex geometries, weight-optimized parts, or production scalability from rough stock.

“Hot Rush” Jobs

An inventory of common materials; extensive amount of machine tools; expert machinists; and a determination to do what it takes to help customers has made this a valuable service. Upon receipt of an inquiry, we verify “MMM” – Material, Man and Machine availability, and quickly respond to the customer, if the needs can be met (or not). This has resulted in many customers releasing ‘Hot Rush’ work to OneMonroe on a T&M basis (i.e. Confirm price after job is done).
