Centex Machining Operations


Engineered quotes are created in the ERP system with input from operations, quality, and production control. At Centex we feel it is critical to get individuals from key areas involved to assure the smoothest transition from the quote to live production. Input on possible manufacturability issues and even cost reductions are also reviewed and delivered to the customer for their consideration and assessment during the quote process.

Once the job is awarded engineering, will detail out the production router and create any additional documents or internal CAD’s needed to process the product. This may include customer specifications and procedures as well as industry standards (e.g. – ASTM, MIL, etc.) which will be detailed on the router to assure compliance at each and every operation. Additionally, engineering will work with quality to get the inspection plans for the in-process and final inspection steps defined and released.

Following production, the job will be reviewed by engineering and operations for any possible improvements that can be made within the established process. If there are any processing issues they will be addressed through corrective actions or other methods to assure additional future orders do not have repeat issues (as applicable).


Operations are managed through controlled and established processes for repeatable and reliable results. All processing materials in the production area are defined in a documented and controlled procedure to assure all possible contacting agents are known and acknowledged. Detailed work orders assure accurate processing. Job tracking is maintained through the ERP system for real time job status and performance.

At Centex we are an all Mazak CNC mill and lathe facility. This common platform eases the cross training process and creates a familiar machine control for our machininsts. This allows Centex the flexibility to quickly move our human resources to areas that have increased demand.

Operations run 24 hours 5 days a week to allow maximum asset utilization. Our production scheduling and the ability to quickly move resources allows for rapid deployment of production increases without compromising quality or delivery demands.

Production Control

Centex operates an integrated ERP system to assure accurate tracking and planning of all jobs both internal and at OSP operations. Every step from initial quote, raw material orders, job schedules, work order processing, OSP operations, and through invoicing are managed through the ERP system.

Daily cross functional meetings are held to assure all areas of the organization are aware of current orders as well as upcoming projects. These meetings assure that all key personnel are aware of any production issues, upcoming and new production requirements are determined, and immediate needs are addressed promptly and accordingly.

The production control team handles all OSP details and raw material buying through the use of approved and monitored suppliers. Total compliance is critical and our supply base is no exception.



Centex’s quality management system operates under the most stringent operating principles available – performing to ISO 13485 and ISO 9001 international quality standards, and FDA regulations, including cGMP.

That’s meant a big investment in both equipment and professional personnel, but it also means our processes are proven and repeatable, our inspections are precise, and our products meet our client’s requirements every time.
