What happens here

The machine shop houses two CNC lathes and three CNC mills, vital for producing components like raw aluminum forgings. A raw forging of an upright (left-hand) is shown, contrasted with a fully machined version, demonstrating the precision required for hub pack and steering arm mounting points. Sean is seen operating a CNC lathe, producing steel bushings. These bushings are critical components for lower control arms, with tight inner diameter tolerances, ensuring a snug fit and durability.

Goal: Illustrate the precision machining of forged and cast components.

Tools and materials

  • CNC Lathes Haas — Turning cylindrical parts with high precision
  • CNC Mills Haas — Cutting and shaping complex parts from solid blocks of material
  • Machined Aluminum Upright Detroit Speed — A finished upright component after CNC machining, ready for assembly
  • Raw Aluminum Upright Forging — The starting material for a machined upright, which forms part of the front suspension
  • Steel Bushings — Providing wear-resistant pivot points in suspension components, produced on CNC lathes

it's our machine shop so we got two cnc lays three mils so over here matt just got done running our spindles so this is a raw forging all right it's aluminum this is our left hand upright all right you just saw that on those cars that matt showed you they were on both those chevelles it was on that mustang also so this is how it comes to us right here it's got our logo in it it's made in the usa it's got our part number on it we'll get we have multiple fixtures in here that will run this on there and we'll locate again the upper ball joint lower ball joint the three holes right here for the hub pack and then these holes for our steer arm and then caliper mount dude those use the corvette hub pack yep yep so on the illuma frame we can offer both a forward bolt pattern and a gm bolt pattern of as far as the hub pack goes over here sean's running these steel bushings right here something real simple oh that's the exciting stuff yeah bushings so he's running about 1200 of them so these go on all of our lower control arms four per car so he's got a tight tolerance on the id that he has to keep and we'll see these in a little bit where we weld them onto a control arm so this is our welding shop so in here this is where we do all the dirty work all the fun stuff we're welding everything that we produce here they're running uh roll cages right now
