What are CNC and NC?

In-depth research on the precision manufacturing and high-quality forging solutions in the forging industry, combined with precise CNC processing, promotes the continuous upgrading of modern industry. These comprehensive capabilities enable us to meet the increasingly complex demands of modern manufacturing. But what exactly is CNC? In this comprehensive guide, we explore the history, technology, applications and advantages of CNC, especially the significance and background of why it is necessary to discuss CNC in the context of the forging industry.

What are CNC and NC?

CNC and NC are both forms of equipment combined with computer numerical control, which utilize computers to automatically control processing tools. CNC machine tools parse digital files and use them to precisely control the speed, cutting volume, tool movement, and spindle movement. These machines are indispensable when manufacturing parts that require strict tolerances and repeatable precision. Unlike manual processing, CNC machine tools operate automatically once programmed, minimizing the possibility of human error and relatively ensuring the consistency and stability of batch products.

CNC enables companies like Weforging to produce complex, high-precision parts on a large scale with high efficiency, providing traceability of CNC products from the source of materials and forging. The coordination of the entire process, from forging, inspection, CNC turning, CNC milling services to CNC grinding machines and CNC gear hobbing and shaping, ultimately leads to the high reliability of the product. We offer tailor-made solutions to meet strict industrial standards.

The Development of Numerical Control Technology in Manufacturing Industry

The concept of CNC can be traced back to the 1940s, when early numerical control (NC) machine tools were developed. These machines were originally controlled by perforated paper tapes. In the 1970s, the development of microprocessors led to the birth of modern CNC machine tools. Today, CNC technology encompasses the integration of CAD/CAM software, human-machine dialogue, real-time monitoring, and the automation of linked production across multiple axes and multiple devices.

Integrating CNC into the forging workflow adds incredible value. Forged components have inherent strength and yield toughness due to the alignment of their grain structure, and when paired with CNC machining, they meet precise geometric and surface finish requirements. For instance, our CNC milling processing technology enables us to process complex features into forged blanks with minimal material waste.

Comparison between Numerical Control and Traditional Processing

In traditional mechanical processing, the operator manually relies on experience to perform various operations such as swinging and rotating the equipment to achieve the cutting of the workpiece. In contrast, CNC machining uses programming instructions to precisely and consistently guide the tool to work in coordination with the spindle and tool rest, thereby achieving processes such as turning, milling, and drilling.

The advantages of numerical control machining over manual machining include:

Greater accuracy, high repeat positioning precision, and high batch stability
High repeatability, simple operation, and reduced human factors
Faster production speed, reduced labor costs, and the ability to handle complex geometries

Our milling operation is a typical example of how CNC improves traditional methods, providing outstanding results while shortening delivery times.

Key Types of Numerical Control Machining

CNC Milling: Also known as machining center equipment, CNC milling involves using a rotating multi-point cutting tool to remove material from a workpiece. This process is ideal for producing complex shapes and with strict tolerances. We offer 5-axis CNC milling services for forgings and raw materials.
CNC Turning: In CNC turning, the workpiece can rotate while the tool remains stationary, or the workpiece can remain stationary while the tool rotates. This process is typically used for cylindrical parts, such as shafts and bushings.
CNC drilling: CNC drilling offers accurate and efficient hole-making capabilities. It is often used in combination with milling and turning for the production of multi-functional parts.
CNC Grinding: The precision processing by grinding machines enhances the flatness, surface finish and dimensional accuracy of parts. When the workpiece components need to rotate at high speeds, it becomes particularly important. In applications, the high precision of bearing positions and bearings is a common application scenario, and this process is indispensable.
CNC Gear hobbing and Shaping: Gears are crucial in the transmission of various machinery. The precision and strength (forging) of gears determine their lifespan and the noise of the equipment. The precision of gears requires high-precision gear grinding machines and grinding wheels.

The manufacturing technology of each process directly affects the reliable performance of the product, so CNC equipment plays a crucial role in the manufacturing field.
