CNC turning is a machining process where the workpiece rotates while a fixed cutting tool removes material. Think of it as an “advanced pottery lathe”: the spindle spins the workpiece at high speed while the cutting tool follows a programmed path to shape it. Ideal for shaft and rotational parts.       CNC turning has become a mainstream process in precision hardware machining due to four core advantages: ① High precision and repeatability, as program control guarantees highly consistent specifications for batch – produced parts; ② High – efficiency integration, modern CNC lathes are equipped with automatic tool changers and live tool turrets, which can integrate operations like drilling, milling, and tapping to shorten delivery time; ③ Wide material adaptability, capable of processing various metals such as stainless steel, aluminum alloy, titanium alloy, copper, as well as engineering plastics; ④ Flexible adaptability, suitable for both small – batch prototyping and large – volume foreign trade orders, widely applied in manufacturing precision parts for industries including automotive, aerospace, medical, and electronics. CNC turning is a subtractive manufacturing process. Its core lies in using computer – programmed cutting tools to precisely machine a high – speed rotating workpiece for material removal. The workpiece is clamped in a chuck and rotated at high speed, while the cutting tool feeds along paths such as the X and Z axes. It can finish multiple operations like external turning, boring, facing, threading, and grooving in a single setup. Unlike conventional lathes, it achieves automated machining via digital programming, with tolerances reaching ±0.005–0.01mm, suitable for batch and custom production of various rotational hardware parts including shafts and disks.

Precision cutting of metal or plastic with rotating tools, ideal for flat and complex-shaped parts.     CNC milling has become one of the preferred processes for precision machining in various industries due to multiple advantages: First, high precision and repeatability. Computer program control greatly reduces human errors and ensures high uniformity of specifications for each batch of parts; second, high efficiency and automation. Equipment equipped with an automatic tool changer (ATC) can continuously complete multiple processes without frequent manual intervention, significantly improving production efficiency; third, strong processing flexibility, which can adapt to diverse processing needs from simple planes to complex 3D curved surfaces, especially good at manufacturing special-shaped structures; fourth, wide material compatibility, which can process various metals such as stainless steel, aluminum alloy, titanium alloy, and copper, as well as engineering plastics such as ABS and polycarbonate, and carbon fiber composite materials. It can efficiently adapt to needs whether it is small-batch custom prototyping or large-batch mass production. According to the machine tool structure and the number of axes, CNC milling is mainly divided into three-axis, four-axis and five-axis milling: three-axis milling is suitable for the processing of simple planes and three-dimensional structures, with convenient operation and controllable cost; four-axis milling adds a rotating axis, which can process parts with inclined surfaces; five-axis milling can realize multi-directional linkage processing, accurately complete the integrated manufacturing of complex curved surfaces and special-shaped parts, and is the core equipment in high-end fields such as aerospace. Its application scenarios widely cover aerospace, automobile manufacturing, mold processing, medical equipment, electronic industry, etc. Typical processed parts include UAV connectors, auto parts, mold cavities, precision components of medical devices, electronic product casings, etc., providing key support for the R&D and production of core products in various industries.

5-axis CNC machining is an advanced form of milling that represents the highest level of precision and complexity. As the name suggests, it adds two rotational axes (typically A and C) to the standard three linear axes (X, Y, Z). Ideal for machining parts with complex geometries.     With its unique technical advantages, 5-axis CNC machining is widely used in core high-end manufacturing fields such as aerospace, medical equipment, automotive manufacturing, and high-end molds: In the aerospace field, it is used to process complex curved surface parts such as aircraft engine blades and spacecraft structural parts, meeting the high-precision processing needs of difficult-to-process materials such as titanium alloy; In the medical equipment field, it produces implants such as artificial joints and dental implants, ensuring biocompatibility and use safety with micron-level precision, complying with the ISO 13485 medical industry certification standard; In the automotive manufacturing field, it adapts to the mass production of new energy vehicle motor housings and transmission special-shaped components, improving product performance and production efficiency; In the high-end mold field, it processes complex cavities and cores of injection molds and die-casting molds, ensuring mold precision and improving the qualified rate of finished products. In addition, it also plays a key role in the processing of turbine components in fields such as wind power and energy equipment. 5-axis CNC machining has become a core supporting technology for high-end manufacturing with four core advantages: First, integrated full-process processing. One-time clamping can complete the processing of multi-faceted and complex structures, which can reduce the number of clamping times by more than 80% compared with traditional 3-axis machining, greatly reducing positioning errors; Second, ultra-high precision and stability. Through real-time optimization of tool posture and multi-axis linkage compensation, micron-level machining accuracy can be achieved, while ensuring the consistency of batch parts and improving the surface finish to below Ra0.8μm; Third, extremely strong processing flexibility. It can accurately process complex components such as impellers, mold cavities, and medical implants that cannot be completed by 3-axis/4-axis machines, adapting to the high-value-added production needs of multi-variety and small-batch; Fourth, significantly improving production efficiency. The processing cycle is shortened by optimizing the cutting path. For example, the processing cycle of new energy vehicle motor housings can be reduced from 120 minutes to 45 minutes, while reducing tool wear and lowering comprehensive production costs.
