Large Capacity CNC Machining, Welding And Fabrication Since 1986
From precision CNC machining to structural welding and custom fabrication, J-Mac Completion Equipment builds, repairs, and certifies the heavy equipment that keeps oil and gas and construction crews running, all from one 120,000 square foot complex in Fort Worth, Texas.
Four Decades Of Heavy Equipment Expertise
J-Mac Completion Equipment has served operators across the oil and gas industry since 1986. What began as a trusted source for used well service equipment has grown into a full service CNC machining, welding, and fabrication complex built to support heavy duty projects from first cut to final delivery.
Built On Oilfield Experience Grown Into Full Service Manufacturing
J-Mac Completion Equipment LLC was founded in 1986 in Fort Worth, Texas, with a focus on connecting operators with dependable frac pumps, blenders, and well service equipment. Four decades later, the company has expanded into a 120,000 square foot manufacturing complex spanning 15 acres, where CNC machining, welding, plasma cutting, industrial coating, and full assembly and testing all happen under one roof.
Today J-Mac Completion Equipment combines the hands on knowledge of an equipment dealer with the precision of an in house CNC machine shop, giving customers in construction and oil and gas a single partner for sourcing, building, repairing, and certifying the heavy equipment their operations depend on.

Answers To Common Questions
J-Mac Completion Equipment was founded in 1986 and has operated in Fort Worth, Texas for more than 40 years, growing from an oilfield equipment dealer into a full service CNC machining and fabrication complex.
The company operates from a 120,000 square foot facility on a 15 acre industrial campus at 8703 Eagle Mountain Circle, Fort Worth, Texas 76135.
Yes. J-Mac Completion Equipment sells both new and used frac pumps, blenders, and oilfield equipment, and also manufactures custom components through its in house CNC machining and fabrication shop.
J-Mac Completion Equipment primarily serves operators in Texas, Oklahoma, Louisiana, and New Mexico, with equipment and parts shipped nationwide upon request.
CNC machining stands for computer numerical control machining, a process where computer guided cutting tools shape metal into precise components. It is commonly used to produce large, heavy, or tightly toleranced industrial parts.
Most CNC machine shops, including J-Mac Completion Equipment, work with carbon steel, stainless steel, aluminum, and other industrial alloys, with the exact range depending on the machine and tooling available.
New equipment typically carries a full manufacturer warranty and the latest specifications, while well maintained used equipment can lower upfront cost while still meeting field demands, especially when it has been tested and certified before sale.
Routine hydrostatic testing and certification confirm that frac iron and hoses can safely handle field pressures, which helps operators stay compliant and reduces the risk of failure on location.
