Computer numeric control (CNC) machining is a manufacturing process that automatically shapes or forms metals or other materials into highly precise parts. This is done through the manipulation of raw materials by machine operated cutting tools. Precision CNC machining systems are equipped with a computer consisting of one or more microprocessors and storage units. CNC machine suppliers utilize specialized software in conjunction with CAD/CAM software systems to instruct the tooling to execute the exact movements necessary to create the part. Precision CNC machining is a highly automated process that requires very little attention from workers. Operators only need to load materials and make any adjustments to the design parameters in order for a CNC machining operation to run unattended for a certain period of time. Precision machining is an efficient and quick way to precisely produce detailed parts.

CNC machine suppliers provide systems that can consist of a number of detailed operations including grinding, turning and precision laser work. They are essentially modern milling machines and the range of available procedures is vast. The process more generally begins with the loading of a "raw" metal piece referred to as a billet. This piece of metal may have been cast, forged or rolled. It is then cut via laser or other device to create highly detailed work, as in the case of laser CNC machining. The milling done by a CNC machine requires little "finishing" to remove rough edges or blemishes, but some post production work may be required to meet safety regulations.

The majority of the operations of a CNC machine take place on what is called a lathe. This lathe performs any operations which require the rotation of the piece in order for the cutting or milling to take place. Parts like the lathe require frequent calibration to ensure accuracy of operation. The maintenance required to keep a CNC machine working does make it a more expensive operation than other types of metal forming, yet the accuracy of the final part is greater, and the range of services available is much wider. Since acute angles are virtually impossible to create using a standard forging or molding technique, CNC machining has become the preferred metal machining method for many industries.

It is important to know the parameters of a machine part that is needed when utilizing CNC machine work services. Many CNC machine suppliers and service providers will create the design code based on specifications given them. Often the CNC machining systems are able to take an existing part and create code based on photo imaging programs. Some companies will take a CNC file and create the parts on their machines. Many shops are able to handle both continual and short-run orders. A few CNC operations can create a decent amount of waste material, so looking for a shop which has appropriate, up-to-date recycling methods is crucial to saving material and money in the long run.

Types of CNC Machining Services, Precision CNC Machining, and CNC Machining Suppliers, and CNC Machine Work.

• CNC drilling is an automatic machine process utilizing a drill to cut parts.
  
• CNC machine shop is a place where materials are shaped by CNC machines.
  
• CNC milling, also known as "CNC turning," is possibly the most common kind of CNC machining. CNC milling machines are classified according to the number of axis points that they use. Typically these machines have at least three axes, X and Y for horizontal movements, and Z for verticals; some machines, however, utilize five axis points with extra pivot points.
  
• CNC punch machines cut parts on computer numeric control systems.
  
• Machine work shapes materials into precise forms.
  
• Precision laser machining is the precision cutting of parts with a laser using CNC machines to control the laser to ensure accuracy.
  
• Precision machining is the process that uses a computerized machine to ensure exactitude.
• Prototype machining is often performed by CNC machines to create a part or object which will be a "mock-up" or model of a future final part. Prototypes are used to prove feasibility, but often are not as efficient or well-designed as later production models.
