CNC, or computer numerical control machining, is a widely used manufacturing process. It uses automated, high-speed cutting tools to form designs from metal or plastic stock, including standard CNC machines include 3-axis, 4-axis, and 5-axis milling machines, lathes, and routers. Machines may vary in how CNC parts are cut—the workpiece may remain in place while the tool moves, the tool may remain in place while the workpiece is rotated and moved, or both the cutting tool and workpiece may move together. CNC machines can cut almost any metal alloy and rigid plastic with high precision and repeatability, like aerospace, medical, robotics, electronics, and industrial.

Application of CNC Machining Services
Wooden furniture is often CNC machined to save time and reduce cost. Manually carving wooden parts is extremely time-consuming and costly. CNC machines can be used to create furniture with complex geometries that would have otherwise required a master woodworker to achieve.
Lettering and Engraving Systems
Some applications don’t require the heavy-duty removal of material, but rather make use of an engraving tool to mark patterns or text onto the surface of a part. This application can be done for artistic applications or serialized parts.
Electrical Industry
Demand for CNC-machined parts for the electronics industry covers a wide spectrum of applications. Machining component mounting holes into printed circuit boards and machining aluminum or copper heat sink for heat-generating electrical components are some examples of the use of CNC machining in the electronics industry.

Benefits of CNC Machining Services
After the operator has programmed the machine with the necessary design specifications, production can take place. Once the CNC machine has started a production run, creating parts takes no time at all. As well as producing large numbers of parts, modern-day CNC machines are also very scalable. What makes them different from conventional machines and manual production processes is that a CNC machine can be programmed to produce one single item or large quantities. There are no limitations to the number of parts you can manufacture, allowing companies to use their resources and finances more efficiently.
Another of the numerous advantages CNC machining offers is its higher speed. When CNC machines are used, operators can be much more efficient because the machines can use their fastest settings. CNC machines can run 24/7 without running out of steam. They don’t need a break for coffee or lunch. No holidays need to be booked or any kind of time off. There are no trade-offs with a CNC machine.
When more conventional milling methods are used, an operator is often required to manually operate the machine and change tooling depending on the cutting operation needed. This can be exceedingly time-consuming and inefficient.
A CNC machine usually has a rotating carousel that can carry up to 30 tools. These tools can be automatically swapped out during the milling and machining process. CNC milling machines with sophisticated design software produce complex shapes that a regular manual machine cannot duplicate. CNC machines are much more efficient than any engineer, no matter how skilled or experienced. With the right software, a CNC machine can produce a workpiece of virtually any size, shape, or texture.
The CNC machining process can create virtually any component you might think of. These machines can perform a wealth of fabrication and CNC milling operations, including shearing, flame cutting, punching holes, and welding metal sheets. Because of their incredible precision, CNC machines can be used to produce shapes of extreme complexity.
CNC machines are compatible with a range of materials such as composites, metals, carving foam, rigid foam, phenolic materials, and plastics. Regarding material selection for CNC milling, factors such as design tolerance, fastening, hardness, stress resistance, and heat tolerance must be taken into account when choosing.
Main CNC Machining Operations in Our Services
CNC machining is a manufacturing process suitable for a wide variety of industries, including automotive, aerospace, construction, and agriculture. The process encompasses several different computer-controlled machining operations—including mechanical, chemical, electrical, and thermal processes—which remove the necessary material from the workpiece to produce a custom-designed part or product, including:
CNC Drilling
Drilling is a machining process which employs multi-point drill bits to produce cylindrical holes in the workpiece. In CNC drilling, typically the CNC machine feeds the rotating drill bit perpendicularly to the plane of the workpiece’s surface, which produces vertically-aligned holes with diameters equal to the diameter of the drill bit employed for the drilling operation. However, angular drilling operations can also be performed through the use of specialized machine configurations and workholding devices. Operational capabilities of the drilling process include counterboring, countersinking, reaming, and tapping.
CNC Milling
Milling is a machining process which employs rotating multi-point cutting tools to remove material from the workpiece. In CNC milling, the CNC machine typically feeds the workpiece to the cutting tool in the same direction as the cutting tool’s rotation, whereas in manual milling the machine feeds the workpiece in the opposite direction to the cutting tool’s rotation. Operational capabilities of the milling process include face milling—cutting shallow, flat surfaces and flat-bottomed cavities into the workpiece—and peripheral milling—cutting deep cavities, such as slots and threads, into the workpiece.
CNC Turning
Turning is a machining process which employs single-point cutting tools to remove material from the rotating workpiece. In CNC turning, the machine—typically a CNC lathe machine—feeds the cutting tool in a linear motion along the surface of the rotating workpiece, removing material around the circumference until the desired diameter is achieved, to produce cylindrical parts with external and internal features, such as slots, tapers, and threads. Operational capabilities of the turning process include boring, facing, grooving, and thread cutting. When it comes down to a CNC mill vs. lathe, milling, with its rotating cutting tools, works better for more complex parts. However, lathes, with rotating workpieces and stationary cutting tools, work best for faster, more accurate creation of round parts.
Process of the CNC Machining Services
The overall CNC machining process consists of four main steps, as listed below:
Designing the CAD Model
A CAD (Computer Aided Design) 3D model is developed by an engineer or designer. This part is designed according to specific CNC design principles, which are included in the overall DFM (Design for Manufacturing) philosophy. DFM ensures that the part can be efficiently manufactured on a CNC machine. For CNC parts, it is not strictly necessary to create 2D drawings of the part, since the machine instructions are created using CAM software which generates machine instructions. However, 2D drawings are often generated to indicate key dimensions for quality control purposes.
Converting the CAD File to a CNC Program
The CAD file is exported to a CAM (Computer Aided Manufacturing) software package that contains a range of tools to convert the 3D model into a set of instructions that can be understood by the CNC machine. CAM software is normally used by CNC machine operators to generate G-code. At the end of the process, a G-code file is saved to the machine. This file contains all the relevant instructions required to manufacture the part.
Preparing the CNC Machine
Preparing the machine to fabricate a new part number starts with setting up the required fixturing to hold the raw stock material in place while the cutting tool removes material. Alternatively, the raw stock is fixed in a spindle and stationary cutting tools are presented to the rotating stock piece to remove material. The required tooling must be checked for wear or chips and placed into the machine. More advanced CNC machines have automatic tool changers and tool libraries that allow the machine to automatically select the relevant tool needed to machine a specific feature without having to wait for the operator to swap out tools.
Executing the Machining Operation
When the material is securely clamped into the machine, the correct tooling is selected and the G-code is loaded, the actual machining can commence. Once the cycle-start button is pressed the machine will select the appropriate tool, move to the workpiece and begin removing material as per the G-code instructions and will continue until the part is complete. For operations that require machining with more than one type of tool, or with the part in more than one orientation, some CNC machines may require the operator to reposition the in-process work material between operations.
Different Types of CNC Machining Machines
The earliest numerical control machines date to the 1940s when motors were first employed to control the movement of pre-existing tools. As technologies advanced, the mechanisms were enhanced with analog computers, and ultimately with digital computers, leading to the rise of CNC machining.
CNC mills are capable of running on programs comprised of number- and letter-based prompts that guide pieces across various distances. The programming employed for a mill machine could be based on either G-code or some unique language developed by a manufacturing team. Basic mills consist of a three-axis system (X, Y and Z), though most newer mills can accommodate three additional axes.
In lathe machines, pieces are cut in a circular direction with indexable tools. With CNC technology, the cuts employed by lathes are carried out with precision and high velocity. CNC lathes are used to produce complex designs that wouldn’t be possible on manually run versions of the machine. Overall, the control functions of CNC-run mills and lathes are similar. As with CNC mills, lathes can be directed by G-code or unique proprietary code. However, most CNC lathes consist of two axes — X and Z.
In a plasma cutter, a plasma torch cuts the material. The process is foremost applied to metal materials but can also be employed on other surfaces. In order to produce the speed and heat necessary to cut metal, plasma is generated through a combination of compressed-air gas and electrical arcs.
Electric-discharge machining (EDM) — alternately referred to as die sinking and spark machining — is a process that molds workpieces into particular shapes with electrical sparks. With EDM, current discharges occur between two electrodes, and this removes sections of a given workpiece.
When the space between the electrodes becomes smaller, the electric field becomes more intense and thus stronger than the dielectric. This makes it possible for a current to pass between the two electrodes. Consequently, portions of a workpiece are removed by each electrode. Subtypes of EDM include:
Wire EDM: Wire EDM uses spark erosion to remove portions from an electronically conductive material.
Sinker EDM: Sinker EDM utilizes an electrode and workpiece soaked in dielectric fluid for the purpose of piece formation.
In a process known as flushing, debris from each finished workpiece is carried away by a liquid dielectric, which appears once the current between the two electrodes has stopped and is meant to eliminate any further electric charges.
In CNC machining, water jets are tools that cut hard materials, such as granite and metal, with high-pressure applications of water. In some cases, the water is mixed with sand or some other strong abrasive substance. Companies often shape factory machine parts through this process.
Water jets are employed as a cooler alternative for materials that are unable to bear the heat-intensive processes of other CNC machines. Due to their cooler nature, several sectors like the aerospace and mining industries rely on water jets, where they use them for carving and cutting, among other functions. Companies also use water jet cutters for applications requiring very intricate cuts in material, as the lack of heat prevents any change in the material’s intrinsic properties that may result from metal on metal cutting.
