J & J Burning and Fabricating assumes single-source responsibility for fabricated and precision machined complete steel parts. With Horizontal Mills to 56', Vertical Mills to 12' diameter and Planer Mills 15' X 40', we can handle your steel machining requirements on parts from one pound to 120,000 pounds. The precision equipment and CNC controls allow us to supply components with tight tolerances up to +/- .0002".

During more than five decades of producing quality steel fabrications, we have developed partnerships with the highest quality machine shops in the Midwest. These collaborative relationships allow us to offer notably competitive prices and quick lead times on machined complete steel components without being captive to one source or limited by in-house capacity.

What Is Machining?

Machining is any of various processes in which a piece of raw material is cut into a desired final shape and size by a controlled material-removal process.

The precise meaning of the term machining has evolved over the past one and a half centuries as technology has advanced. In the 18th century, the word machinist simply meant a person who built or repaired machines. This person's work was done mostly by hand, using processes such as the carving of wood and the hand-forging and hand-filing of metal. At the time, millwrights and builders of new kinds of engines (meaning, more or less, machines of any kind), such as James Watt or John Wilkinson, would fit the definition. The noun machine tool and the verb to machine (machined, machining) did not yet exist. Around the middle of the 19th century, the latter words were coined as the concepts that they described evolved into widespread existence. Therefore, during the Machine Age, machining referred to (what we today might call) the "traditional" machining processes, such as turning, boring, drilling, milling, broaching, sawing, shaping, planing, reaming, and tapping. In these "traditional" or "conventional" machining processes, machine tools, such as lathes, milling machines, drill presses, or others, are used with a sharp cutting tool to remove material to achieve a desired geometry.
