CNC Machining & Welding of an Aluminum CRT Housing Assembly

Offering experienced staff and precision machining equipment, our 8 CNC machining centres and CNC lathe capability provide the necessary production capacity for virtually any product design. At Larsen Tella LLC, we provide high-quality products with very short lead times.

An Aerospace company asked us to produce a CRT (Cathode Ray Tube) housing assembly made from Aluminum. The housing needed to be machined to 13″x 7″x 8.5″ with tolerances as tight as + .001″, in accordance with the customer’s strict requirements. The material also required conversion coating in accordance with MIL-DTL-5541 specifications.

The housing’s complexity demanded in-house CNC machining for 7 different components, supported by assembly operations that also included welding. We employed both vertical and horizontal CNC machining centres, producing each of the 7 parts for the housing. Each part was individually assembled, and then welded to the final assembly. Adhering to our reputation for quality and precision, all parts underwent a series of dimensional checks during the process including CMM validation using callipers, micrometres, and various fixtures.

Impressed by our ability to combine both precision CNC machining and various assembly operations in rapid time, our customer continues to order CRT Housings at a rate of 2,000 units per year. To learn more about our CNC machining capabilities, please contact us or refer to the table below.
