A customer in the heavy equipment industry needed a company with the experience and resources to machine a support assembly for use within a control panel support. As a recognized producer of precision components, National Technologies was commissioned to fabricate the assembly as highlighted below. Employing a state-of- the-art multi spindle screw machine, 7/8” hex 1018 steel was machined to the specified profile, reaching 4.5” in length. Our newly acquired Hass drill/tap machine was then utilized for the accurate and rapid drilling and tapping detailing procedures. The component was etched as specified, assembled and thoroughly washed to ensure the removal of all machining debris.

Dimensional and visual inspections were carried out to verify accuracy; along with a static torque inspection to ensure the 221 ± 52 lb-in torque spec was met. 10,000 units were manufactured in a turnaround time of 4 weeks and shipped to the customer as agreed. The success of this project resulted in a profile in CNC Machining Magazine, and a lasting manufacturing relationship with this client. For more details about this support assembly fabrication or the other multi spindle screw machining capabilities available please see the table below or contact us directly.
