Flame Cutting

CNC Flame Cutting for Precision Steel Parts

Benedict-Miller's state-of-the-art machine shop offers you flame cutting of steel plate, sheet, and round bar for high quality precision steel parts with quick turnaround times and exceptional cost savings. Our highly trained personnel are expert at cutting 4130 (E4130) steel and 4340 (E4340) steel up to 6" thick, ensuring a smooth burn and the right cut edge to the surface of the plate.

CNC flame cutting uses an oxy-fuel flame torch that moves across a plane to burn cuts of specified dimensions into the material. Using your DXF files for cutting precision parts to your exacting specifications, our flame cutting machines can cut:

  • Steel up to 6" thick
  • Steel plate 72" x 144"
  • Shapes
  • I.D., O.D.
  • Straight line beveling
  • Tight tolerances
  • Smallest to largest quantity (no minimum!)

Flame cutting can produce burnouts (parts) in varying shapes and thicknesses which can be finished with any of our metal services such as grinding.


After your precision parts are cut, they are re-annealed in our furnace to remove the heat affected zone. The heat affected zone is the area of the base metal where the mechanical properties and microstructure have been altered by the heat of the cutting operations. Re-annealing is done to ensure uniform anneal and to remove hard edges that can cause wear-and-tear on machining and cutting tools.

Single Source for All Your AQ Steel Needs

From raw material to flame cutting or plasma cutting and metal services, you can get everything you need from a single, trusted source with years of experience supplying OEMs, distributors, service centers, tool and die shops, and business owners from aerospace, automotive, auto racing, off-road, transportation, construction, alternative energy, defense, and a variety of other industries.

How We Save You Money

Using a 3D CAD design file to optimize the layout of parts for cutting, our CNC flame cutting machines are equipped to 'nest' shapes onto the cutting material. This process not only saves time but it saves you money by minimizing the amount of raw materials that could potentially be wasted by poor placement. A lean manufacturing practice, our nesting program is also kind to the environment.
