What is Precision CNC Machining

Precision CNC (computer numerical control) machining is a manufacturing process that utilizes computer-controlled machines to produce complex parts and components. It is an essential process for multiple manufacturing industries, including military and defense, aerospace, oil & gas, automotive, trucking, medical, and general industrial manufacturing to mention a few.  Parts produced through a precision CNC machining process must meet rigorous standards. These standards ensure the safe and reliable operation of the systems in which CNC produced parts are employed. Parallel Ventures in Tucson, Arizona provides precision machine parts to several of the above industries. A few examples of precision machined parts include the following: 1) missile bulkheads 2) missile body sections 3) missile fins and fin components 4) automotive Kingpins 5) airplane body and wing machined parts 6) medical devices 7) medical equipment machined components 8) material handling equipment machined parts 9) oil & gas exploration and drilling components 10) mining equipment components.

Subtractive Manufacturing vs Additive Manufacturing

Precision machining is a subtractive manufacturing process. This process removes material from a stock piece of metal or plastic to produce a required part configuration. Additive manufacturing is sometimes referred to as 3D printing. It basically involves adding multiple layers of material to each other to produce the desired part configuration. Additive manufacturing has been in the news for the past several years as the manufacturing process of the future. However, subtractive manufacturing has been around since mankind began whittling sticks. Today, precision CNC machining is still the more common process used to produce complex manufacturing parts and components. Additive manufacturing processes are crucial to many industries. Consequently, as this technology continues to develop and grow, additive processes may one day be the preferred method of manufacturing complex parts. However, precision machining will continue to be a vital part of US manufacturing today and far into the future

5 Reasons Precision Machining is Vital to US Manufacturing

Precision CNC Machining in Medical Industry


In many manufacturing industries, precision machining is used to produce safety critical components. For example, missile guidance systems and aircraft landing gear are often machined parts. Any error in the manufacturing process could lead to catastrophic consequences. Therefore, precision CNC machining is crucial to the safety of military personnel and civilians alike. The medical industry is another example of an industry where human lives depend upon the safe performance of parts and components. Patients and doctors rely daily upon the precise and safe operation of medical equipment in doctor’s offices and hospitals in countries throughout the world. 


Precision machining ensures that components are manufactured to exacting requirements, minimizing the chance of failure or malfunction. This is especially important in the defense and space industries. Defense and Space equipment must be reliable in extreme environments and conditions.


Precision machining ensures that parts and components meet high quality specifications. Machine parts are often produced with consistent high-quality standards even in high volume manufacturing environments. Parallel Ventures utilizes extremely accurate CNC milling machines and lathes. Consequently, in conjunction with our inspection Coordinate Measuring Machines, we ensure that all delivered parts and components meet every exacting customer requirement and specification.

Precision CNC Machining Cutting Tools


CNC machines used in precision machining can produce parts and components quickly and efficiently, reducing production time and costs. In a globally competitive market, it is crucial that US suppliers continuously improve production cycle times. As a result, manufacturers are able to satisfy customer and market commercial needs. 

Innovation and Customization

Precision machining enables the production of custom parts and components tailored to specific applications. Also, precision machining makes it possible to create highly specialized equipment, thereby allowing for the development of new and innovative designs that push the boundaries of what is possible.


In conclusion, precision machining of parts is critical to US manufacturing for several reasons, including but not limited to safety, reliability, quality, efficiency, customization, innovation, cost-effectiveness, consistency, and global competitiveness. By utilizing precision machining, US manufacturing companies can produce high-quality parts and components quickly and efficiently. Therefore, these companies remain competitive on a global scale while delivering innovative products that meet the needs of their customers.
