Precision machining plays a considerable role in creating many of the parts, tools, components and equipment that we use on a day-to-day basis.
From composing tiny parts used in electronics to the parts used in automobiles, boats, rockets and skyscrapers, just about any piece of machinery, product or equipment that requires a high level of accuracy depends on precision machining.
Precision Machining Definition – What is It?
Precision machining is a machining process that uses computer numerically controlled machining and milling tools with the oversight of a precision machinist to shape, cut and remove excess materials from a workpiece to meet the dimensional specifications for a finished part or component.
Since no two parts can be created identically, a permissible degree of deviation is allowed to exist between any two products’ final dimensions.
Precision Machining Definition & Uses in Industry
Tolerances play a critical role in the manufacturing process, as finding the right level of tolerance has a direct impact on turnaround time and manufacturing costs.
Other Common Machining Definitions and Roles
Precision Machine (Definition): A high-precision machine tool that is used to achieve extreme levels of accuracy. Examples of machines used in precision manufacturing include lathes, grinders, CNC milling machines, a cutting tool (like saws and drill presses) and even high-speed robotics.
Precision Manufacturing (Definition): Precision manufacturing is defined as a process that removes excess raw material from a workpiece while achieving the tight tolerances required to create a finished product.
CNC Manufacturing (Definition): Computer numerical control (CNC) manufacturing involves a wide range of automated manufacturing processes where CNC machining tools cut, mill and shape raw material to meet specifications defined in CAD software.
Computer-Aided Design (CAD): CAD software helps aid in the creation, analysis, and optimization of a design while serving as the product’s blueprint where Computer-Aided Manufacturing (CAM) software then translates those specifications into automated manufacturing instructions for CNC machines.
What is Precision Machining Used For?
Precision machining is a highly precise and efficient manufacturing process that is used when parts need to be machined with a high degree of accuracy and uniformity. If a part demands tighter tolerances, then high-precision CNC machining tools are used to reach set standards.

Precision Machining Applications (By Industry)
Much of modern manufacturing is dependent on the wide-scale applications and pinpoint accuracy of precision machining. To gain a better understanding of the importance of precision machining, let’s take a look at how it impacts the following industries:
Aerospace Industry
Precision machining has been serving as the backbone of aerospace innovation because of the extreme accuracies and tolerances that can be achieved. Where single errors can lead to severe damages, precision is a necessity. Additionally, CNC precision machining processes are responsible for making many of the components this industry depends on, such as:
➤ Navigational systems
➤ Interior wall panels
➤ Landing gear ports
➤ Bushings
Automotive Industry
With the surge in electric vehicles and innovations at the forefront of the automobile industry, precision machining processes are often used to design and develop the exact specifications for a part or component needed before being added to the assembly line. Common examples of machined parts include engine blocks, wheels, water pumps, and transmissions.
Precision Machining Definition & Uses in Industry
Military and Defense Industry
From developing the composite skins on the F35 fighter jet, the communication components on an SAT radio, to prototyping and creating ammunition, precision machining has never been as prevalent as with military and defense. With different nations using different military and defense schematics, the depth of parts and accuracy required is immense and are ripe for CNC machining.
Medical Industry
The medical industry relies on innovations in medical equipment and technology to make advancements that improve our health and way of life. Without precision machining, many of the parts in the medical field wouldn’t be available. Common examples include MRI machines, surgical tools, implants, orthotic devices, safe enclosures and research equipment.
