About CNC Machining
CNC machining allows for high volume output as well as rapid prototyping. CNC machining uses computers to guide machinery and tools during the manufacturing process. Once a CNC machine is started, all cuts and movements are controlled by the software. There is no hands-on maneuvering of the tools, which helps reduce manufacturing overhead and prevents accidents.
Many industries use CNC machining, including aerospace, electronics, metalwork, production, transportation, agriculture, automotive, construction, oil and gas and more.

Comparing CNC Machining Processes
DFM (Design for Manufacturability) – the initial phase of any CNC process is designing the end piece to be completed using CNC machining. DFM involves establishing a workpiece’s overall design and machinability to ensure it is simple to manufacture.
3-Axis CNC Milling – In 3-axis CNC milling, the workpiece remains motionless while the cutting tool mills along three different axes. 3-Axis milling machine applications include contoured shapes, hole features, and sharp edges.
4-Axis CNC Milling – With 4-axis CNC milling, the CNC machine operates on multiple axes, with an additional rotation around one of the axes. This additional rotation is called the A-axis. It is used to create cut-outs on the side of a workpiece.
5-Axis CNC Milling – 5-axis CNC milling machines utilize all 4-axes of 4-axis machining plus an additional rotational axis (B-axis). 5-axis milling machines can produce complex parts for various industries.
9-Axis CNC Mill Turn – The 9-axis CNC machine is similar in basic capabilities of the 5-axis machine but also includes angle milling, balance turning and more. 9-axis machines use both the B-axis and additional tools to create complex parts.
Horizontal Milling – With horizontal milling, multiple circular cutting heads are mounted to a horizontal arbor. The bed of the machine moves horizontally or may even rotate.
Vertical Milling – In vertical milling, the cutting head is oriented vertically on the milling machine. In a turret milling machine, the cutting head is fixed while the bed of the machine with material moves horizontally or vertically.
Turning – In turning, the workpiece is held and rotated while single-point tooling starts to shape the material. The cutting tool is moved linearly along the surface of the material to create the desired shape.
CNC Routing – With CNC routing, the routing machine holds the material, spindle, controller, and drive system. The spindle cuts while the drive system acts like an arm moving in three directions as directed by the controller. Materials such as plastic and some metals are suitable for routing machines.
Surface Grinding – A surface grinding machine uses a rotating wheel to extract material from the workpiece. It is commonly used during the finishing process, particularly when a piece needs a complete finish.
Broaching – The process of removing material from a piece using a toothed tool which is called the broach. The two types of broaching include rotary and linear (linear being the more common process)
Boring – the removal of material from a workpiece using tooling to drill holes into an object
Lapping – Lapping is the process of removing any remaining unwanted material from a produced piece. Lapping may include the use of coarse material such as glass plus an abrasive such as diamond. This combination is rolled between the two surfaces to remove material.
Polishing – A polishing machine, like lapping, works to remove any unwanted material from the workpiece. The result is a mirror-like finish free from any imperfections.
Welding– When it comes to CNC machining, some machines can support welding. This is an automated process that uses traditional welding techniques from a CNC perspective.
Post-Weld Machining – Post-weld machining is a secondary finishing process. During this stage, the part is further refined to meet the exact specifications of a project.
Hardware Insertion – Hardware insertion involves inserting a fastener with another material using extreme compressed force.
Wire EDM Cutting – EDM (aka electrical discharge machining) cutting involves using an electrical spark to cut the desired material.
Waterjet Cutting – This style of cutting utilizes a high-power water jet to cut materials. The water often contains a coarse material to aid in cutting.
CO2 Laser Cutting – Carbon dioxide laser cutting uses infrared light to cut various materials.
Fiberoptic Laser Cutting – Fiberoptic laser cutting involves laser diodes diffused through optical fibers. Through this process, cuts can be made into the desired material.
Mechanical Assembly – putting together the final piece; can involve several initial CNC processes to create initial parts.
CNC Milling vs. CNC Turning
CNC milling and CNC turning are different processes. One big difference is that turning is primarily used for making cylindrical components while milling can be used for various shaped parts. CNC milling leverages a specific tool that rotates to make cuts and shape a component. In CNC turning, the material itself spins to allow for the cutting device to shape and form the final product. In the end, each process has its benefits. It all depends on the details and need of your end part.

Available CNC Part Finishes
Anodizing – Anodizing helps with reducing corrosion and enhancing your part with a more metallic look to your aluminum parts. It can reduce scratching, act as an electrical insulator and is also a very durable finish.
Types of Anodizing Specifications:
- Type II
- ROHS compliant
- Clear (class 1)
- Black (class 2)
Chromate Plating – Chrome plating also provides protection for your parts from corrosion but also adds electrical conductivity to your part. It also provides the ability to paint the part. Certain metals will require special pre-treating to take full advantage of chrome plating.
Types of Chrome Plating Specifications:
- Yellow (Type I, Non-ROHS)
- Clear (Type II, ROHS)
- Class 1A: For protection against corrosion in either painted or unpainted state
- Class 3: For protection against corrosion in situations where low electrical resistance is required
