What is precision machining?
Precision machining can be defined as utilizing the maximum capabilities of tools, procedures, engineering talent, or equipment to the limits of manufacturing and materials science, and performing these operations within the tightest tolerances of those manufacturing. Precision machining is a machining and manufacturing process that plays an irreplaceable role in the production and design of machines, parts, tools and other hardware that are indispensable in modern manufacturing, and can ensure that the equipment required by modern society is under extremely strict conditions Operate under specifications. Precision machined parts are used to make up many of the large and small objects and their components that we use in our daily lives. If an object is made up of many small parts, these small parts often need to be made with precision machining to ensure they fit together precisely and work properly. Clearly, precision machining has evolved over time, and advances in all related technologies help push the limits of defining precision machining and consistently improve performance. The true art of precision machining comes from the combination of computer controlled design and human engineering to create unique features and highly controlled output and functionality, driven by fluid dynamics, chemical control, mechanics, extreme weather and durability required by modern hardware advances in this technology. Precision machining is especially important for manufacturing tools and parts in a precise, consistent and repeatable manner with accuracy, consistency, and durability.
What are the uses of precision machining?
Precision machining is a subtractive process used where material needs to be removed from raw materials to create finished products. Precision machining can be used to manufacture a wide variety of products, items and parts from any number of different objects and materials. These parts are usually required to have very precise dimensions, which means that there is not much room for error in the production of the parts. Repeatability and well-controlled tolerances are hallmarks of precision machining.
The most common use of precision machining is to produce assemblies, parts and finished products that maintain extremely tight tolerances and are highly durable. For example, parts that work together as part of some machine may need to be aligned at all times to within the tiny dimensions of 0.01 mm to 0.05 mm. Precision machining helps ensure that these parts are not only manufactured precisely, but are produced repeatedly with this level of precision.
Another common application for precision machining may be when a tool or component needs repair or restoration. After a period of use, a tool or part of an object may require machine alignment, notching or welding to return to its original condition. This can also be done with precision machining.
How does precision machining work?
Precision machining is a subtractive process in which operators use custom software, tools, and fixtures to place metal, plastic, ceramic, or composite materials into processing equipment in a precision machining facility, and then produce the desired fine-featured product . Precision machining typically follows instructions given by computer-aided design (CAD) and computer-aided manufacturing (CAM) programs. These procedures and instructions ensure precision part tolerances. While most designs end up being CAD, many start with hand sketches in the initial stages.
What equipment and raw materials are used for precision machining?
Precision machining works with a variety of raw materials, including metals, plastics, ceramics, composites, and more. For precise machining, a variety of equipment is available to achieve the desired size and shape. These tools vary by raw material. Common tools include mills, lathes, electrical discharge machines (aka EDMs), saws, and grinders. The most commonly used manufacturing equipment are computer-controlled CNC machining centers and CNC lathes, designed to remove excess material and create detailed components and parts.
