Precision machining is what produces a huge number of both large and small objects that we use in daily life. Each intricate piece which makes up an object requires one level or another of a machinistís skills. Likewise, a tool or machine that has been worn down will often require machine tool calibration, welding or grooving by a precision machinist. From the production of aircraft aluminum alloys to surgical bone drilling devices and custom automotive tools, precision machining reaches into every technology and industry. In other words, if an object contains parts, it required precision machining.
Quality precision machining requires the ability to follow extremely specific blueprints made by CAD (computer aided design) or CAM (computer aided manufacturing) programs like AutoCAD and TurboCAD. The software can help produce the complex, 3-dimensional diagrams or outlines needed in order to manufacturer a tool, machine or object. These blueprints must be adhered to with great detail to ensure that a product retains its integrity. While most precision machining companies work with some form of CAD/CAM programs, they still work often with hand-drawn sketches in the initial phases of a design.
Precision machining is used on a number of materials including steel, bronze, graphite, glass and plastics to name a few. Depending on the size of the project and the materials to be used, various precision machining tools will be used. Any combination of lathes, milling machines, drill presses, saws and grinders, and even high speed robotics may be used. The aerospace industry may use high velocity machining, while a woodwork tool-making industry might use photo-chemical etching and milling processes. The churning out of a run, or a specific quantity of any particular item, can number in the thousands, or be just a few. Precision machining often requires the programming of CNC devices which means they are computer numerically controlled. The CNC device allows for exact dimensions to be followed throughout the run of a product.
