There are not many more demanding environments in which parts must function than the transportation industry. Many of these components began their lives as forgings that were then machined, which was the case when at Aurora Custom Machining we were asked by a client to manufacture steel flywheels for transportation. Our team started with a 3300 lb. forging of SAE 1045 steel. CNC OM-60 and Honor Seiki SL-125 vertical turning lathes, Enshu 650V vertical mills, and Machining Systems 630 horizontal mills were used to machine the forging, which was then balanced. Final dimensions of the flywheels were-OD: 43.625", ID: 8.00", and depth: 5.56", all of which were verified by dimensional and visual inspections. Working from customer specifications and a 2D CAD drawing, we manufactured these flywheels to rigid tolerances of ±0.001". Our experienced employees made eight of the flywheels in only three weeks for delivery to a Midwest customer.

At Aurora Custom Machining, we were asked to manufacture a turbo component for a customer in the transportation industry. This project was very demanding because the scroll was fabricated from an expensive casting and it included complex interior dimensions. Working with ASM cast iron, we started with the casting and used our CNC OM-60 vertical lathe, a YCMTV1588 vertical machining center, and our CNC Fortune 630 horizontal machining center to manufacture the turbo intake scroll. After deburring, the scroll was subjected to both dimensional and visual inspection. This component, which was 302mm high and weighed a little over 167 lbs., was fabricated to exacting tolerances of ±0.050mm from a 2D CAD drawing and according to rigid customer specifications. Our team manufactured five of these intake scrolls in only six weeks for delivery to a satisfied customer in the Midwest.

At Aurora Custom Machining, we are known as experts at manufacturing wear components from high-grade irons. This is the reason a customer asked us to manufacture close grain iron spider couplings for them, which were wear components of rock crushers used in the mining industry. These heavy duty systems are designed to reduce large rocks to smaller rocks, gravel, or dust. A CNC Okuma V80 vertical lathe and a YCM TV1588 vertical milling machine was used to turn, mill, drill, and tap the coupling casting, which was made from CL501 close grain iron. Following deburring, our team performed dimensional and visual inspections to verify we met the precise tolerances specified by the customer of ±0.002”. We worked from a 2D CAD drawing to manufacture these 421-lb., 11.161” high couplings, whose outside diameters were 27.953”. Our staff manufactured 28 of the spider couplings in only two weeks for delivery to the customer in Illinois.
