About Precision Machine Tools and Their Uses

Precision machine tools are used for machining and shaping rigid and/or metal materials by grinding, boring, cutting, shearing and other methods of transformation. All varieties of machine tools are built to provide ways of constraining the work surface and produce a carefully guided motion of the various parts of the machine in question, make it a free hand process.

Today machine tools are for the most part hydraulically, by line shaft or electrically used to produce manufactured parts/components in numerous ways and are built with precision enabling the economical manufacturing of interchangeable parts. Most tooling companies carry extensive product lines of metal cutting machines varying from horizontal and vertical milling machines (bed and knee type), precision and tool room surface grinders, lathes, cylindrical grinders, electric discharge machines and radial arm drills.

Precision machining produces a significant number of objects of various sizes that we all use in everyday life. Every intricately formed piece that makes up an object necessitates one degree or another of a professional machinist’s skills. That being said, precision machine tools that have been worn down will in many cases need calibration, grooving or welding by an experienced precision machinist. From the manufacturing of automotive tools to aircraft aluminum alloys and surgical bone drilling devices, precision machining extends into each and every industry and technology. In other words, if an item consists of parts, it called for precision machining.

These Precise tools are used on a wide range of materials that include bronze, steel, graphite, plastic and glass just to name a few. Depending upon the size and intricacy of the project and the components to be applied, a variety of precision tools will be used. Projects requiring machining may call for a combination of saws, drill presses, milling machines, lathes and even state of the art high speed robotics in some cases.

High quality precision machining necessitates the ability to adhere to specific blueprints created by computer aided design (CAD) computer aided manufacturing) applications (CAM) like TurboCAD or AutoCAD. These software programs are used to help produce the intricate, 3 dimensional diagrams or outlines that are required to manufacture a tool, object or machine. These detailed blueprints need to be followed in great detail to make certain that the product maintains its integrity. Although the majority of precision machining firms use some kind of CAM/CAD programs, they also work with hand drawn sketches at times in the initial stages of a design.

The precision machine tools used vary greatly depending on the industry as well. For example the aerospace industry is likely to use high velocity machining; on the other hand a woodwork tool making sector would more than likely use milling processes and photo chemical etching. The rolling out of a specific volume of any object can be in large volumes or just make a few. Precision machining can at times require the programming of CNC instruments meaning they’re numerically controlled via computer. CNC devices make it possible for exact dimensions to be implemented for the duration of the run of a product.
