  • Cox has over 270 spindles capable of machining complex parts from 4mm to 2.625” in diameter, run by a skilled team of 170+ highly trained employees, scheduled three shifts a day. This guarantees the depth and flexible capacity to support your high-volume production orders are out the door on time and on spec.


  • Cox is located in and fully operating out of San Antonio, Texas and has been since it was established in 1956. Cox is a logistically ideal supplier of precision machined components without the long supply chain worries, risks of intellectual property loss, and assorted integrity issues that third world and overseas sourcing can bring.


  • Cox is ISO certified and ITAR registered, commonly handling PPAP and DFARS standards required by the world’s most demanding industries.
  • Beyond this, Cox has developed a proprietary patented “Advanced Unity Control” Quality System that leverages Industry 4.0 technology to interpret real-time machine data and quality statistics that takes shop floor quality to an unprecedented level and applies the system to every job.


  • Cox routinely operates Kanban and other customer-driven quality and inventory management systems, all managed with our proprietary ERP software that integrates functions across the company.


  • Being a high-volume production machining and screw machine products supplier, Cox specializes in annual contracts and blanket orders with min-max inventory agreements, as well as fixed firm orders, to consistently supply your parts at optimal costs and delivery at reduced inventory levels.


  • As a domestic supplier with decades of expertise and broad industry experience supported with an extensive in-house engineering group, Cox commonly assists customers in lowering the “Total Cost of Ownership” through a variety of strategies we are always willing to offer to high-volume buyers. There is no time better than the present to start looking for savings! 

Another cost-cutting partnership springs from our geographic position along the productivity pipeline between the US and Mexico. Cox is a logistically ideal source for precision machining tasks that are beyond the scope of Mexico suppliers. We can also manage an entire production process in-house, or through partnerships with Mexico affiliates. The result is world-class savings without the logistics worries, freight costs and intellectual property losses third world and overseas sourcing can bring.
