Industries Using Precision CNC Machinery

Computer Numerical Control (CNC) Machining creates numerous detailed parts required in dozens of industries.  Many industries require custom-created parts for specific uses rather than mass production.  The ability to accurately design and create pieces with a computer is the key factor many companies are looking for.  Industries including the medical field, transportation, the military and more rely on machining parts.  Since the technology that makes up computers and machines advances daily, this allows for more intricate and customized designs to be achieved.  

Precision is what is needed in the medical, aerospace, electronics and other industries.  If any of these parts are not manufactured with a high degree of precision and held to tight tolerances, serious product defects could result 

Machining uses many different devices such as milling, Swiss screw machining and machine turning.  The machine operators choose the best method to use based on the required precision of the product and content used. 

  • Machine turning – like a lathe, CNC milling machines turn the material but a computer controls the entire process.  This makes mass production of parts possible 
  • Swiss Screw machining – requires an expert for set up and needs extra time but produces the most precise parts within 0.005 inches 
  • Machine milling – turns the tools around the piece and the mills can use numerous tools for highly detailed parts.  

By using the right machine and material for the job, CNC machinists can serve in a wide range of industries.  Each of these industries have their own needs which means that all of the different options that can be used in CNC machining will be not necessary for every business.  

Medical Industry 

The medical industry relies on customized products to fit the many needs of their patients.  Many devices used in the medical field are disposable to protect patients from infectious disease.  Businesses in this field require precision and high volume parts to fulfill the needs of their facilities.  Sometimes the companies may request prototypes of the product before requesting a full run especially if they are testing out new ideas.  CNC machines adapt well in the medical field due to the variety of materials and devices available.  Here are some of the parts that can be created by CNC machining: 

  • Implants 
  • Orthotic devices and screws
  • Electronic enclosures for monitoring devices 
  • Research equipment 
  • Shielded enclosures 
  • MRI Machines 
  • Electrical parts 
  • Customized packaging to maintain sterility 
  • FDA approved production 
  • Pieces made from high temperature plastics 
  • Medical instruments 

These machines include the rapid creation of customized parts and manufacturing done in an environment approved by the FDA.  When making individual designs, the computer allows the engineers to see the piece in 3D before machining it.  This ensures every part has the exact dimensions required.  These parts must have the smallest possible margin of error to avoid medical misdiagnoses and part malfunctioning.  Our ability to manufacture to tight tolerance with consistency coupled with superior quality control has set Sheldon Precision apart from competition within the medical industry.  

Aerospace Industry

High speeds, fast air currents and extreme pressure are three conditions devices in the aerospace industry encounter on a daily basis.  To avoid damage to the aircraft, engineers muse precisely construct every component.  CNC machining for the aerospace and aviation industries must meet high precision requirements which often reach as tight as 0.0004 inches.  Machinists must create these tolerances with extra durable materials such as titanium, aluminum, nickel, alloys and plastics.  The materials used will depend on the parts created and properties desired from that component.  Parts made for the aerospace and aviation industry include many different components of aircraft and the devices that service them including: 

  • Manifolds 
  • Bushings
  • Airfoils 
  • Landing gear parts 
  • Electrical connectors 
  • Antennae 
  • Radio frequency suppression materials 

Without the ability to design and create multiple precisely made parts, the air and space industry may not have reached the technological level that it is at today.  CNC machining is ideal for manufacturing prototype parts.  By seeing the 3D image on a computer, the engineer can make quick changes to the design based on testing.  Once the design has been finalized, the CNC machining process for one or multiple parts can begin.  Similar to the military and defense industry, the aerospace industry has demanding standards.  Sheldon Precision utilizes modern CNC machining to produce accurate and reliable components use in many aerospace applications.  State of the art machinery and skilled operators turn our precise components in a variety of materials including aluminum and titanium. 

Military and Defense Industry

The military industry is similar to the petrochemical industry where they use parts that need to be rugged and durable for every environment and climate.  The military has strict regulations set forth by the government and the products produced need to adhere to these regulations.  The parts created for the military can be similar to those produced in the aviation, transportation, electronic, marine and medical industries.  Though the parts may be similar, they don’t have the needs of the defense sector to keep up with the latest technology and having parts that reliable in the most out of reach locations.  These parts can include: 

  • Communications components 
  • Electronics 
  • Transportation components 
  • Plane parts 

Due to the strict regulations and security measures, the exact products and procedures used for creating military equipment require secrecy.  CNC machining can create quick upgrades, long lasting parts, creation of parts from robust materials and mass output of approved parts that require tight tolerances.  If CNC machines are being used, regular testing and upgrades of the devices must be done to allow the technology to be the most up to date to help ensure the best protection for our country.  Accuracy, precision quality and dependability are indications of the components Sheldon Precision manufactures for the military and defense industry. 

Electronics Industry

CNC machining can be used to create both large and small parts such as the sizes needed in the electronics industry.  Some of these elements will require laser precision to produce the parts with fine accuracy up to 10 micrometers that may be required.  In addition to electronics and insulators commonly found in electrical devices, the electronics industry may also need communications components.  These parts can protect communications devices from electronic interference or create electrical connections between elements such as: 

  • Heat sinks
  • Amplifier housings 
  • Radio frequency interference shielding 
  • Electrical insulation 

The smaller the parts needed, the tighter the tolerances.  There is little room for error in the micro machining process.  By using a CNC machine, it increases the accuracy levels humans would not be able to achieve.  The electronics industry greatly benefits from this precise accuracy for components, housings and other parts.  Electronic, telecommunications and wireless products require precise components and smaller sizes.  Sheldon Precision has the experience and capability to manufacture a wide variety of components to any size and tolerance.

CNC machining can be used in a wide variety of industries and are able to create parts out of multiple types of materials.  If you are looking to use CNC machining for your products, contact us today for a custom quote at
