Get High-Quality CNC Machined Parts from a Trusted China Manufacturer

What Is CNC Machining?

CNC machining is a manufacturing process, often used for rapid prototypes and low volume manufacturing.

It is a subtractive process, in which a variety of tools, such as drills, lathes, and grinders cut away at a piece of raw material, which can be plastic, aluminum, stainless steel, or another type of material.

The machining tools are all controlled by a computer, hence the name CNC, which stands for “Computer Numerical Control.”

At our factory in China, experienced machinists work at CNC turning and milling stations, providing the instructions needed for the cutting tools to quickly produce your precision CNC machined parts.

Industries We Serve

CNC machining has been at the forefront of machining technologies used in the aerospace and defense industry for over three decades. And this is due to the extremely high precision CNC machines offer, making them ideal for creating many safety-critical parts, such as landing gear and engine components, missiles, and combat vehicles.

While precision remains integral to the performance of optical components and systems, most of the materials used for laser housing products and other optical components are extremely difficult to machine. CNC machines are helping to accurately fabricate optical communication parts made of silumin, iron-nickel, and copper alloy materials.

CNC machining is a widely used process in the robotics and automation industry for fabricating robotic end effectors, custom jigs and features, and storage units. Because CNC machines can achieve tolerances of ±0.05 mm and surface roughness of Ra 0.8μm, product designers can ensure robotic part dimensional accuracy.

The automotive industry relies on CNC machining to create prototype components made from specialty lightweight metal alloys and composites. Machinable automotive parts include engines, roof panels, lighting, and transmission systems, among others. CNC machining is also useful for creating many custom automotive parts, especially for limited-edition luxury vehicles.

CNC machining is the most popular machining technology in the electronics industry because of its advantages such as low labor costs, high productivity, and precise complex shapes manufacturing. 3-, 4-, and 5-axis CNC machines are especially useful for fabricating electronics housings, panels, heat sinks, and other miniaturized electronics parts.

In recent years, the medical industry has seen a high demand for high-precision machining services for producing implants, medical devices, and surgical instruments. Through custom CNC machining, machine shops accurately create these parts while meeting the requirements of several regulatory bodies, such as the U.S Food and Drug Administration (FDA) and ISO 13485.

As the demand grows for more stringent semiconductor component specifications, the semiconductor industry is adapting accordingly by getting rid of conventional machining techniques and relying on CNC machining to manufacture parts. CNC machining is also making it possible for semiconductor designers to easily achieve different surface finishes, including anodizing, nickel-plated, and masked finishes.

Solar, wind, and hydropower turbines and generators play a vital role in powering other industries. These power generation facilities feature many complex components made of different metal alloys and reinforced carbon fiber plastics. They are usually fabricated using CNC machines.

How CNC Machining Works: An Overview

How Does CNC Machining Work?

CNC machining is a subtractive manufacturing process that employs computerized controls and machine tools to remove portions of a stock material till the desired custom part is made from the workpiece.

The machining process starts with the creation of a CAD (Computer-Aided Design) model of the desired part, which is then loaded into a CAM (Computer-Aided Manufacturing) software and converted to a set of computer instructions.

This set of instructions (or G-code) allows the machine to execute different cutting operations at high speed (thousands of RPM) till the desired custom part is made.

How Does CNC Machining Compare to 3D Printing?

Both CNC machining and 3D printing rely on CAD files and computer inputs to transform a starting material into desired custom parts. However, unlike the subtractive CNC machining process, 3D printing is an additive machining process. It revolves around adding materials in layers to build the desired custom part.

CNC machining offers a wide range of material options, whereas 3D printing only works with plastics, polymers, and a few metals that are available in powdered form. Additionally, CNC machined parts are usually stronger than 3D printed parts; as such, CNC machining is ideal for prototyping and production of functional parts.

What are the Different Types of CNC Machining?

CNC machines come in many varieties, with each type having its unique functions.

CNC turning and milling machines feature built-in tools for cutting and drilling the workpiece till the custom CNC part is made. They are available in 3-, 4-, and 5-axis configurations, depending on the part complexity.

The CNC milling process involves the workpiece being held in place while the cutting tools rotate around it, whereas in CNC turning, the workpiece is rotated around the fixed cutting tools to create the desired shape.

Unlike CNC milling and turning machines that rely on cutting tools, CNC Electric Discharge Machines (EDM) utilize electric sparks to manipulate materials into the desired shape.
