A manufacturer of Microwave connectors needed a stainless steel, right-angle connector body manufactured. At Kroll Technologies LLC, we specialize in CNC Swiss machining, with extensive precision milling and tooling capabilities that were required to make this complex part. Our Citizen C32 was used for the required turning, milling, thread milling, drilling, boring and grooving needed to make this 303 stainless steel connector body. We also provided ancillary processes including de-burring, ultrasonic part cleaning, de-ionized water rinse and an in-house citric passivation. The finished component was machined to a 32 µin finish with overall dimensions of .451" in length and a diameter of .875". We utilized automated vision systems to ensure accurate dimensional inspections for tolerances of ±.0005”. Samples are also sectioned to expose internal geometry for measurement. We manufacture 20, 000 pieces annually for this customer with an average turnaround time of 4 weeks for smaller individual orders. At Kroll Technologies, we are one of the few Swiss CNC machining companies that can manufacture parts requiring this type of extensive milling, thread milling, and other live tool work.

Kroll Technologies LLC utilizes the latest Swiss CNC machining technologies to manufacture the most complex and tightest tolerance parts for multiple industries. For this project, a customer in the fiber optics industry needed a connector body made from 316L stainless steel, which is capable of handling harsh environments. This project required the use of a Star SW-20 Swiss lathe, which features an opposing gang-type tool post and a tool post with Y-axis control. These state-of-the-art machines are specifically designed for maximum efficiency of complex parts. Once machining is completed, the body goes through automated ultrasonic part cleaning, de-burring, and nitric passivation to remove any potentially corrosive residue from the steel. The overall dimensions of the part were 1.5" in length with an outer diameter of .625" and inner diameter of .103", with a 32 RMS µin finish. At Kroll Technologies quality is key, and is maintained by our multiple inspections conducted during and after machining. Dimensions with tolerances as tight as ±.0002" are verified with precise automated vision system inspections. Initial quantities can be delivered within 4 weeks. We manufacture 3000 parts annually for this Pennsylvania customer.

In support of increased demand from our Pennsylvania based customer, Kroll Technologies LLC was selected to provide regular deliveries of Aerospace Fastener Blanks. Our customer supplied us with 2D CAD drawings of this component. As is done for all part projects, Kroll Technologies' Engineering team performed a comprehensive design review to ensure manufacturability as well as a complete quality plan by Quality Assurance. We started with .1875" diameter, A-286 Iron Based Super Alloy. The ultra-close tolerance of .0001" (2.5 microns) required us to machine these on our most recently purchased Swiss-type CNC Automatic Lathes. Cutting tools can breakdown rapidly when machining super alloy triggering near constant dimensional drift, A-286 is no different. Consequently, maintaining tight tolerances proves all the more difficult. Kroll Technologies simply flexed its staffing resources to tackle the challenge. After the parts were machined, they were degreased and cleaned using an automated ultrasonic cleaning system. Final part dimensions were .435" (11.04 mm) in length with a diameter of .1457" (3.70 mm). 100% dimensional inspections were performed using indicating micrometers, optical comparator and one of our Keyence IM-6020 vision measurement systems. We provide this to our Pennsylvania customer on a time schedule of 6 weeks. This project highlights our capability to manufacture exotic and difficult to machine material while maintaining extreme precision.
