We offer CNC machining, CNC vertical honing, deep hole drilling, and assembly of major braking, clutch, and engine components to partners who manufacture locomotives and diesel engines, and conversion projects for more sustainable inner city mass transit systems. 

  • Resilient wheels, solid wheels, wheel sets, axles, gearboxes, brake saddles, hub discs, shafts, shafts armature, press discs, bearing sleeves, axle quills, spider bevel gears, rollers, rings, pinion shafts, brake saddle hubs.


Coleys is experienced in making nearly every component on the truck axle and suspension, as well as transfer case housings and their internal components for over-the-road trucking, straight trucks, and trailers.  Every week we provide CNC turning, CNC milling, and stocking programs for thousands of precision parts.

  • Backbones, knuckles, axles, drop axles, axle end hubs, kingpins, spindles, journals, spindle pins, hub seal journals, axle end shafts, flanges, brake flange plates, hub rings, steer axle spindles, tubes, tie rods and plates.
  • Complete management of suspensions and axle components. Machining, welding, and stocking programs.


Looking for a CNC machining partner in the Transportation industry? With the use of our services, you’ll experience:

  • A one-stop-shop. Everything you need for CNC machining is offered conveniently in one place. Components that are assembled are procured, burned, and formed, then assembled at Coleys. We machine the formed parts, machine friction welded components, and have them welded at multiple, proven vendors, depending on certifications.  After welding assemblies, we bring them back to Coleys for line boring.  Each individual part is marked or stamped to be welded back to its original components, ensuring the highest quality and concentricity. 
  • Growth commitment. Customers know we invest in all types of equipment each year to streamline projects and add the capacity needed to handle customer growth, including robots to supplement labor.
  • Linear pallet systems. We grow our pallet systems for quick set and changeover of part families. All parts provided weekly and monthly remain set up in the pallet systems for quick changeover.   
  • Special sawing/loading. We built a special machine/department for loading and sawing pre-welded components. We eliminate scheduling interference, as the parts need to be cut immediately to send to vendors for welding, to streamline the lead time.  We save time on sawing with special loading and fixtures, and the cuts are precise with special setup, and hard gaging.
  • Stocking programs. You’ll never need to worry about the lack of material with our stocking programs.
