What Is CNC Milling?
CNC milling is a CNC machining process that used controlling computers and rotating multipoint cutting tools to quickly remove the material from the workpiece and create custom-designed parts.
Through the CNC milling process, we can produce custom milled parts made from various materials such as metals and plastics, and produce a variety of custom CNC machining products.
It’s a subtractive method of manufacturing in which the workpiece is held rigid on a fixture and mounted on a worktable as the material is removed with a rotating cutting tool. The milling cutting tool can move up several axes, up to 5 axes.
Why Choose CNC Milling Services?
CNC milling can be done on a wide array of materials. Custom milled parts can be made from almost any engineering plastic and metal.
Milling parts have high dimensional stability, high machining precision, and high repeatability.
Milling is the most versatile CNC machining process, with high adaptability and flexibility of parts machining.
CNC milled parts can be machined in multiple processes after one set-up; 5-axis CNC milling can be machined on multiple surfaces at one time.
CNC milling service can machine parts with complex shapes or strict tolerance requirements, such as mold parts, housing parts, etc.
Milling CNC machine has a high level of automation and production efficiency and can run 24/7 continuously, which is conducive to the automation of production management.
3-Axis, 4-Axis, 5-Axis For CNC Milling
3-Axis – It’s one of the most widely used techniques to create parts. Standard CNC mills have 3 axes, which allows the workpiece to remain still while the attached cutting tool moves along the X, Y, and Z axes to mill the part.
4-Axis – We use this mill to create more complex CNC machined parts. It incorporates an extra degree of movement by rotating on a vertical axis, allowing greater flexibility and introducing more continuous machining.
5-Axis – These CNC machines are the most advanced and widely used type of CNC mill. The 5-axis mill incorporates three traditional axes and an additional two extra degrees of movement. It operates by adding rotation to both the worktable and spindle.

Custom Finishes
Our provides surface finishing services for CNC Machining Services. We deliver high-quality parts with the smooth finishes of your choice.
Standard aluminum extrusion profiles (like extruded aluminum channel or extruded aluminum bar) are typically mass manufactured by extrusion specialists; if you need large quantities of standard extruded aluminum profiles, you are better off using the services of one of these companies.
However, for custom aluminum extrusion profiles with a nonstandard aluminum extruded shape, WeLink may be a better option. That’s because we accept low-volume extrusion orders — for prototyping and small batch production — allowing you to experiment with custom profiles.
In addition to creating custom aluminum extrusion profiles using custom dies, we can combine extrusion with other manufacturing processes (like CNC machining) to produce custom final parts. This can allow us to make parts faster and more affordably, especially if the majority of the part has a consistent cross-section.

Finishing Options for Aluminum Extrusions
3. Quality is similar from traditional production molds.
Maybe someone worries the quality compared to traditional production molds, actually the parts from our metal rapid tooling, 95% or more quality can be achieved, for example, like surface finishing, parting lines, color, strength etc. those will be not different. Just for some tight tolerance should be a little deviation if there are two many dimensions need to control. All our materials come from reliable manufacturer, like Dupont, Sabic, BASF etc. all material COC can be provided with shipment.
Aluminum extrusion is used to mass produce lots of non-cosmetic parts like tubing and frames, where finishing may not be especially important. However, custom aluminum extrusion is also used to produce high-value products which may benefits from the addition of color, text, logos, and other finishing procedures.
Suitable surface finishing procedures for aluminum extrusion include:Surface Finishing
Surface finishing refers to different processes used to alter the surface of a manufactured product to give it a distinct or desired look and feel. Different techniques are used to improve the appearance, adherence, solderability, resistance to corrosion, hardness, conductivity and many other characteristics of industrial components.
WeLink offers a high quality surface finishing service for all components and parts regardless of the machining method used in producing them. We have some skilled experts who only handle finishing assignments so the quality of work done on your products is of exceptional quality. If you desire a perfect finish for your prototypes and other manufactured components get in touch with our customer services team for a quick and accurate quotation.
Automotive – Car custom parts including gearboxes, turbochargers, and interior panels require CNC milled parts.
Food – CNC milling technology designs components used in food processing machines, blenders, grinders, crushing machines, cleaning devices, and more.
Machine Tool – The tooling industry needs parts such as fasteners, fittings, shafts, hydraulic and mechanical components that are designed using CNC milling technologies.
What Is CNC Turning?
CNC turning is the process of remove material from a rotating workpiece using the linear path of tools on a CNC lathe. In a simple perspective, the main elements involved in this process are the rotating spindle in which your work part is clamped and the cutting tool that is mounted on a turret.
Here at Our’s CNC turning center, we are highly capable of producing complex and critically dimensioned custom parts through our CNC lathes, providing high-quality CNC turned parts in metal or plastic for rapid prototyping or low volume production.
Titanium aerospace parts include airframe and jet engine components, such as discs, blades, shafts, and casings. Many of these can be machined.
Because titanium is harder than aluminum, it can be trickier to CNC machine, causing tool wear and heat buildup. This means aerospace machining of titanium may require a reduced machine RPM and larger chipload. (See our guide to machining titanium for more information.) However, since aerospace machining typically involves the most advanced and high-end machining equipment available, this is rarely an issue.
Aluminum alloys
Another widely used metal in aerospace machining — and one that has been around longer than titanium and modern composites — is aluminum.
Aluminum alloys are lightweight and have a high tensile strength. Aluminum forms an oxide coating when exposed to air, making it corrosion resistant, and it is also highly formable (more so than titanium), making it easy to CNC machine.
Additional Value-Added Services
We strive to provide additional custom manufacturing for our diverse customer base, including expanded secondary operations and surface treatment capabilities. Examples include EDM, wire EDM, anodizing, powder coating, passivation, plating, heat treatment, and final product assembly.
Basic Types Of CNC Turning Processes
The process range of CNC turning is very wide, which can be processed various types of rotary surfaces, such as external turning, internal turning, taper turning, parting, facing, boring, reaming, drilling, knurling, threading, grooving, etc.
O.D. and I.D. Turning – For machining precise cylindrical features (Tool used: General turning tool)
Parting and Grooving – For parting off, or cutting a “groove” profile in either the internal or external part of a part (Tool used: Parting and grooving inserts)
Facing – Flattening the face of the workpiece (Tool used: Facing tool)
Boring and Reaming – Enlarging or finishing of existing holes Rapid Tooling China to obtain highly accurate diameters (Tool used: Boring and reaming tools)
Drilling – Remove materials to drill holes from the inside of a workpiece (Tool used: Drills)
Threading – Machining of threads by turning, may be done in either the internal or external area of the workpiece. (Tool used: Threading tools)
