ATF designs, prototypes and produces parts from billet steel, billet aluminum and composites for many automotive applications. The shop features state-of-the-art HAAS CNC mill and lathe machining centers, Dimension solid model prototyper, SOLX valve body dyno, Lincoln MIG welders, Miller TIG welders and more. Our valve body dyno is used for testing our custom valve bodies. We put them through several checks to ensure you get maximum performance and long life from your ATF valve body. Have any questions?

Prototyping:
Before shiny new billet parts are produced on our CNC machines we create virtual and solid prototypes of them. Prototyping allows us to perfect product designs before the parts go into production. Producing accurate prototypes of parts before they are machined from expensive materials saves time and money.
Pictured below is one component of a solid model prototype for a new bellhousing design.
Machining:
The CNC Mill used to machine flywheels, flexplates, engine plates, engine brackets, valve bodies, valve body plates, drums, pistons and many other items. CNC machining is a complex process where the machine is programmed and then the material (usually a solid block of aluminum or steel) is secured to the table inside the machine. The machine's table and cutting head move while the cutting head carves the part from the material. The cutting head can hold a multitude of interchangeable cutting tools. The tools are selected according to the instructions programmed into the machine. On the right side of the table is a 4th axis. This can be used to cut splines or rotation of a part while machining. CNC machining is extremely precise and can repeatedly produce identical parts within very tight tolerances of quality control.

The CNC Lathe is used to machine valves, shafts, bushings, pistons and any object that is round. The material is spun with the spindle and the tools are used to profile the outside diameter. After all machining is completed, the part is cutoff and caught in the parts catcher.
Here is a quick clip of our new Powerglide stator tube being machined on the HAAS CNC lathe.
Fabrication:
ATF's machine shop is ready to fabricate anything you need from roll bars and roll cages to four link suspensions, custom headers, brackets, accessories, pulleys and more. Our expert fabricators can TIG, MIG and ARC weld anything you need; no job is too large or small.
Valve Body Dyno:
The valve body dyno allows ATF to test the valve body thoroughly. The valve body dyno uses a hydraulic pump to simulate the pump inside the transmission. When testing the valve body on the dyno, ATF verifies that it will shift properly and deliver the correct pressures that the transmission requires. Quick pressure build up on the gauges and no visual leaks from the valve body are just a few of the quality checks that we perform before the valve body can be installed onto the transmission. The dyno also gives ATF the ability to set pressures on valve bodies equipped with pressure regulator valves.
