Precision Machining

What Is Precision Machining?

Precision machining is one manufacturing technique that creates and designs machines, components and accessories, and tools that are indispensable intolerances and maintaining process controls that function under very tight specifications in modern manufacturing. It is used to produce the many large and small components of machines that are used to create objects in our everyday life. If these objects are made up of many small parts, we need high-quality machine tools to ensure that these small parts fit together precisely and function as intended.

Another way you can look at precision machining is that it capitalizes on the highest function of a tool, program, or equipment that pushes the limits of design capability and material science. When machining is performed under these conditions, the tightest tolerances can be yielded by these manufacturing parameters. That said, precision metal processing didn't just appear out of the blue. It also followed an ongoing evolution and advancement of technologies, which helped push the limits of machining processes. A defining example would be the incorporation of computer-controlled design that improved performance significantly and consistently, which is also why it is closely associated with the term "CNC machining".


What are the Applications?

You typically need it when you need to remove raw materials from a product to create a finished product. You can use it to create an unimaginably wide range of products, items, and parts for any number of different objects of various sizes. 

One thing all of these objects intended for high-precision manufacturing have in common is that they all require tight tolerances variation from part to part, meaning errors in the production of the pieces have to be kept at the very minimum. This is why this process features repeatability and a well-controlled production process.

Furthermore, precision machining allows parts and products to be designed to maintain extremely high tolerances and a high level of durability for the robust finishes of the products. What you need to realize is that not only is it required to produce parts precisely, but making sure that these parts can be produced with the highest level of consistency is also just as crucial.

Another application of precision engineering is when you need to repair or restore tools or components. This shouldn’t be unfamiliar for those who take part in the manufacturing field because most machines, tools, and components all required calibration, grooving, or welding to restore them to their primitive state after using them for some time.  


How does it Work?

It is a process by which excessive raw materials are removed from an object while holding close-tolerance finishes to create finished products. In other words, it is a subtractive process where custom software, engineered tools, and process steps are incorporated to work on these raw materials. Materials that can be machined include plastic, ceramic, metal, or composites, all of which can be used to produce fine-toned products. 

Precision machining usually works according to instructions provided by computer-aided design (CAD) and computer-aided manufacturing (CAM) programs. These programs and the relative blueprints allow objects to be machined with tight tolerance. While many designs are ultimately engineered and computer-aided designs, they usually begin with hand-drawn sketches in the preliminary phases.
