The precision machining process uses a diverse array of tools to precisely remove unneeded material and achieve the most complex design criteria for a piece. These processes are used to provide critical components in diverse industries including medical, aerospace, industrial, energy, and hydraulics. This article looks at common applications for precision CNC machined parts.

What is Precision CNC Machining?

Precision machining utilizes advanced, computerized machine tools to achieve the most demanding tolerances and create the complex geometric cuts required for so many of today’s components. A high degree of accuracy and repeatability is achieved through the use of sophisticated computer numerical control (CNC) machine tools. This allows converting a user’s unique designs into exact shapes through multiple dimensions. The benefits of precision CNC machining include:

• Increased speed in the production process
• High degree of consistency from prototype to final design
• Ability to achieve a high level of accuracy and complexity
• Faster cycle times
• Better finishes
• The ability to complete multiple features at the same time
• Improved quality and consistency over high volume requirements

Precision CNC Machining – What are Common Types?

The most common types of precision CNC machining are:

• CNC turning machines and lathes: These machines rotate workpieces during the machining operation, while a cutting tool removes material from the circumference until the desired diameter is achieved. They can also create features such as bores, broaches, drilled holes, slots, tapers and threads.
• CNC milling machines: These machines rotate the cutting tool while holding the workpiece stationary. They produce such shapes as shallow and flat surfaces, as well as cavities in the workpiece.
• CNC laser machines: These machines use a highly-concentrated laser beam to create heat which allows it to precisely slice, cut, or engrave the workpiece.
• CNC electric discharge machine (EDM): Here, highly-controlled electrical sparks are used to produce intense heat and manipulate the materials into a desired shape. EDM works well for very hard metals that are difficult to machine through other processes.

Common Applications for Precision CNC Machined Parts

Precision machined components are supplied to many OEM customers and system integrators for diverse end-markets. Typical products include spools, sleeves, pistons for hydraulic systems, fuel injection system parts, and fuel pump parts for automotive applications. Common applications for precision CNC machined parts include:

• Applications requiring precise repeatability: Once the design has been set through the CNC program, maximum quantities can be produced with a high degree of accuracy. This would apply to decorative pieces, car parts, and industrial equipment.
• Construction: Precision CNC machining can replace the tedious hand-shaping applications in providing construction components for plumbers, pipefitters, and HVAC technicians.
• Medical: Precision CNC machined parts are used in many elements of the medical industry to facilitate patient healing and comfort. Examples of medical applications include orthotic devices, implants, MRI machines, and research equipment.
• Transportation: CNC precision machining can help in developing prototype parts for transportation applications, as well as creating final components for many components of automobiles, tractors, trucks, and ships.
• Aerospace: With its critical safety requirements, aerospace benefits greatly from the use of precision CNC machining. Components used in everything on airplanes include landing gear, manifolds, bushings, valves, and pump parts.
• Robotics: CNC machined parts are ideal for standing up to the rigorous and continuous use of robotics applications. Applications include robotic arms, custom jigs, and storage units.
• Energy: Contributing to more efficient power generation systems, CNC machining is utilized in producing high-tech components for solar, wind, and hydropower generators and turbines.
