Many projects call for the precision provided by computer numerical control (or CNC) machining.Anytime a project requires complicated cuts and various levels and angles, the process can be carried out in mere minutes on a CNC machine. The machine’s functions will perform necessary steps exactly as dictated by software, which means the precision will be repeated across all parts on a production run.

At Precision Machining & Fabrication, we can call on our extensive in-house machining capabilities to provide our clients with exceptional value and quality, even for the most complex projects. We’re equipped with numerous advanced machining systems, including precision CNC equipment from Haas. This equipment represents the cutting edge of machining technology and, in the hands of our seasoned machinists, is capable of producing components with:

  • Tolerances of +/-0.0005″ for straightness, concentricity, and diameter
  • Tolerances of +/-0.001″ on lengths over 24″
  • Dimensions of up to 64″ x 32″ x 30″ for milling
  • Dimensions of up to 16″ in length and 23″ in diameter for turning

Types of CNC Machining

CNC machining is a broad term covering a wide range of computer-guided processes. Some of these include:

Drilling

Drilling relies on the use of multi-point drill bits to create cylindrical holes. The CNC machine follows programmed instructions, precisely controlling the drill bit and feeding it into the surface of a workpiece to produce vertical holes. In some cases, angular drilling can be achieved through specialized machine configurations, tooling, and work-holding devices such as tapping, reaming, countersinking, or counterboring.

Milling

The milling process is reductive, which means it removes material from the workpiece using rotating multipoint cutting tools. While manual milling requires that the workpiece be fed into the machine in the opposite direction of the cutting tool’s rotation, a CNC machine can achieve precise cuts while moving the workpiece in the same rotational direction as the cutting tool. CNC milling is a diverse process, providing related capabilities such as:

  • Face milling. This process is used to cut flat surfaces, or to cut cavities with flat bottoms into a workpiece.
  • Peripheral milling. Peripheral milling is used to cut much deeper cavities, such as threads and slots.

Turning

Turning is also a reductive process that uses one or more single point cutting tools to remove material from a workpiece. The CNC turning machine—also commonly known as a CNC lathe—rotates the workpiece, and the cutting tool removes material around the circumference based on its programmed instructions. This process is typically used to create cylindrical parts.

The CNC turning process can perform multiple functions, such as:

  • Boring
  • Facing
  • Grooving
  • Threading

Other CNC Machining Operations

There are a variety of other processes that can be controlled using CNC processes.

  • Broaching
  • Sawing
  • Grinding
  • Honing
  • Lapping

Materials

CNC machining processes can be used to cut nearly any metal, as well as a variety of other material types, such as:

  • Aluminum
  • Brass & copper
  • Composites
  • Exotic metals/alloys
  • Precious metals
  • Plastics/polymers
  • Stainless steel
  • Steel
  • Super hard specialty alloys

Industries Served

A variety of industries and applications rely on CNC machining for the production of critical parts and components. Whether it’s the siding for a plane or a massive part designed to be installed in a tractor, CNC-machined parts are a critical part of:

  • The automotive industry (automobile frames)
  • The aerospace industry (airplane engine components)
  • The construction industry (building components)
  • The agriculture industry (hand tools, garden tools)
  • The medical industry (medical devices, surgical equipment)
