Industry Focus

Our heavy component machining is frequently used in industries where vehicles, equipment, and machinery tend to be larger than those in typical applications. This approach is used to manufacture parts for a variety of industrial equipment across many industries, such as:

Construction: Excavators, trucks, cranes, bulldozers, pile drivers

Mining: Trucks, tractors, loaders, etc.

Agriculture: Tractors, plows, balers, etc.

Aerospace: Turbines, aircraft, satellites, etc.

Power generation: Gas and wind turbines,etc.

Industrial: various tube sheets and baffle plates, flanges, gears, etc.

Quality Assurance

One of the essential workhorses for product verification is our Coordinate Measuring Machine(CMM). We use it every day to qualify rapid prototypes and machined parts that have complex geometries with tight tolerances.

At Present, we have two ZEISS CMMs-MMZ G large bridge CMM and ACCURA II bridge CMM, and one laser tracker Leica AT901.

Our quality assurance program is focused on providing confidence that quality requirements will be fulfilled, both by our internal staff and through our clients’ expectations.

With our large-scale CNC machining capabilities, Openex is a premier provider of quality machined parts and fabrications. Serving the needs of clients from coast to coast, our facility is equipped with large swing lathes, heavy duty CNC drills, and machining centers that allow us to manage workpieces with oversized dimensions and weighing up to 250 tons. Our machining equipment is located in a high bay area with lifting capacity that enables us to safely maneuver heavy workpieces. We have a staff of technically skilled machinists noted for their fine quality workmanship and attention to detail on each machining project.
