Our Purpose

We will set the price and lead time standards for machined and fabricated parts and assemblies for the aerospace industry. We will drive costs down and mutual profits up through cellular manufacturing and continuous improvement activities.

Our History

Cox Machine was founded in 1954 by Ernest “Bud” Cox. From his experience as a machinist at Cessna Aircraft Company and Kansas Tool, Bud decided that he had the necessary skills to open his own shop.

Over The Years


The Early Years

The Early Years
He constructed a 16 x 20 foot building on his property from scrap wood and began Cox Machine with four tools: a mill, a lathe, a shaper, and a drill press. The drill press was a Christmas present from his wife, Ruth Ann. Initially, finding customers was a difficult task. Bud was still working another job full-time, and he spent nights and weekends trying to solicit work. After six months, he got Cox Machine’s first job. When he received his first check, he used it to buy his wife a gold watch.

Ready to Expand

Ready to Expand
As Bud's reputation spread, he gained some new customers. By 1956, the business had outgrown the small building, and Bud moved Cox Machine to its own site, northwest of Wichita. Cox Machine's original building on this site was purchased from a man who had won the building in a poker game. The building had no plumbing, and so an outhouse was erected on the property, which soon become home to a very large snake.

Capabilities Expand
As Cox Machine continued to grow in size and reputation, the facilities were continually expanded and improved. More and more equipment was added to expand Cox Machine's capabilities.

New President

New President
In 1972, Bud retired from Cox Machine, and his son Steve assumed the role of President and General Manager. Also in 1972, Cox Machine purchased its first CNC machine.



Through the following years, Steve Cox continued to expand the customer base, facilities, and capabilities of Cox Machine.


New Facilities

New Facilities
By 2000, Cox Machine had outgrown its home of 45 years, and construction began on a new site, approximately 1/4 mile east of the original site. Construction was completed in 2001, and the new site now houses Cox Machine's primary Machining Operations, as well as the Administrative Offices, Quality department, Planning and Production Control Department, and Shipping/Receiving.


In 2010, Cox Machine added 30,000 square feet of manufacturing space to the Wichita location. The expansion allows us to continue the creation of manufacturing cells to increase our capacity.

Expansion of Assembly Operations

Expansion of Assembly Operations
Cox Machine constructed a new 50,000 square-foot facility for assembly operations, located directly across the street from their headquarters in Wichita, KS. The expansion is a result of greater customer need for sub-assemblies, and program build-rate increases.
