Manufacturing & Assembly

Our approach

OP Machine’s equipment line up and depth of experience allows us the flexibility to offer our customers a total manufacturing package. Our ability to control all aspects of the production process is key to providing 100% conformance to our customer specifications.  OP Machine’s registration with the ISO 9001:2018 quality management system insures your parts are made to the highest standard with full accountability at all processing steps.


Complementing our production facility is a fully serviced assembly department where knowledgeable staff  can bring all manufactured parts together for a seamless integration into a finished product. Backed by our strong quality assurance program we can ensure assemblies are built to exacting customer specifications with the ability to identify issues and devise solutions as they are detected. This value added service is ideal for customers who wish to streamline their manufacturing needs, lower their overall production costs, and eliminate unnecessary handling between production stages.


Our CNC milling department is the cornerstone in OP Machine’s multifaceted production services. These machines can perform many labor intensive operations with extreme accuracy and consistency, producing quality parts in both production and prototype size lots. Three complete machine centers, two having high capacity tool holders, allows us to accommodate various jobs quickly and efficiently without the need for full tear down and re-setup making time sensitive jobs affordable while having less impact on scheduled work. Fourth axis milling capabilities further reduce manufacturing costs and lead times with fewer setups and operations for complex features.

OP Machine employs both CNC (Computerized Numerical Control) and manual turning equipment enabling us to accommodate a wide array of customer requirements. Large and small production runs are supported by a bar feed system, giving shorter lead times and greater cost effectiveness. Live tooling adds to our CNC Lathes versatility by reducing the number of operations needed for more complex geometries. With the recent addition of a new CNC turning center, our lathe capacity has doubled further reducing part lead time. This now enables us to offer quick turnaround solutions for time sensitive parts where precision, quality, and good value are paramount.
