What are CNC turned parts?
CNC turning parts refertoparts that are machined by computer-controlled machine tools. During CNC machining, it is possible to accurately control the tool to finely cut rotating workpieces according to pre edited programs, producing various shapes, sizes, and high-precision parts.
The difference between CNC turning and CNC milling Both CNC turning and CNC milling are common CNC machining methods, with the main differences being the cutting tools and the way the workpiece is moved, as well as the shapes of the parts that can be machined. CNC turning can be used for drilling, tapping, and hobbing, suitable for machining parts with axisymmetric shapes such as shafts, bushings, and slecves.
CNC milling can process flat surfaces (horizontal, vertical), grooves (key grooves, T-grooves, ant grooves), gears, helical surfaces (threads, helical grooves), and various curved surfaces. suitable for processing complex shapes or features of flat and irregular surfaces, such as grooves, gears, threads, and special forming surfaces of molds
Turning process
The principle of CNC turning technology is to use computer digital control technology to control the movement and operation of the lathe through pre written machining programs, thereby achieving precise turning of workpieces.
Specifically, the principles of CNC turning technology include the following aspects: CNC system, programming code, lathe structure, tool selection, machining process, and quality control.
Numerical Control System: Based on the design requirements of the workpiece, a three-dimensional model of the workpiece is drawn using computer-aided design (CAD) software, and a numerical control machining program is generated using computer-aided manufacturing (CAM) software. The CNC machining program contains information such as the machining path, cutting parameters, and tool selection of the workpiece.
Programming code: Input the CNC machining program into the control system of the CNC lathe. The control system controls the movement of the lathe’s spindle, feed axis, tool and other components according to the instructions in the program, achieving precise turning of the workpiece.
Machine tool control: Input the CNC machining program into the control system of the CNC lathe. The control system controls themovement of the lathe’s spindle, feed axis, tool and other components according to the instructions in the program, achieving precise turning of the workpiece.
Tool cutting: During the turning process, the tool cuts the surface of the workpiece, removes excess material, and achieves machining of the workpiece.The cutting speed, feed rate, cutting depth and other parameters of the tool will affect the machining quality and efficiency.
Precision control: CNC turning technology can achieve high-precision machining by precisely controlling the motion of the machine tool through the control system.In addition,high-precision measuring equipment can be used to measure and inspect the workpiece to ensure that the processing quality meets the requirements.
CNC machine type
The types of CNC machine tools are mainly divided into CNC horizontal machine tools and CNC vertical machine tools CNC vertical machine tools are widely used in industries such as electronics, electrical appliances, communications, and medical equipment. Can be used for machining workpieces with smaller dimensions and higher precision.CNC horizontal machine tools are mainly used in automotive. aerospace, machine tool manufacturing, etc., and are usually used for machining larger sizes and weights of workpieces.
Material selection for CNC machine tools
CNC materials are mainly divided into metallic materials and non-metallic materials. Metallic materials mainly include steel, aluminum and aluminum alloys, steel and steel alloys, titanium and titanium alloys, while non-metallic materials mainly include plastics, nylon, and ceramics. The selection of materials needs to be based on comprehensive factors such as the specific requirements and processing conditions of the parts, and the most suitable materials should be chosen.
CNC lathe tolerance and accuracy
Milling dimensions are 4.6 meters x 500 millimeters, with a minimum sizeof20X20X20 millimeters. The maximum processing size is 3.6 meters x 3 meters, and the minimum size is 0.8x 100 millimeters in outer diameter. The machining accuracy can reach -0.016-0.001 within the outer diameter range of 40 to 50Concentricity can reach 0.03, parallelism can reach 0.008, and smoothness can reach 0.8. The cutting tolerance requirements in hardware processing may vary depending on specific processingtechniques, part uses, materials, and other factors. In some metal stamping processes, the dimensional tolerance requirement for components may be within 0.05mm.
Types of turning parts
There are various types of turning parts, mainly divided into five categories: precision turning parts, shaft parts, flange parts, sleeve parts, and thread turning parts
Precision turning parts have the characteristics of high precision, wide use of materials, strong ability to process complex shapes, and good repeatability. They are generally used in acrospace, medical equipment, electronic devices, automotive manufacturing, mold manufacturing, etc.
Axis components are usually rotating bodies with a certain length to diameter ratio, widely used in fields such as automobiles, machine tools, and construction machinery, such as motor shafts.
Common flange parts include gear discs, flanges, etc.. which are mostly used in automobiles, aerospace, and aviation for connecting and supporting functions.
Sleeve parts have a certain length and wall thickness, and play an important role in mechanical transmission and shaft support, such as bearing sleeves
Threaded turning parts are widely used in the connection and transmission parts of various mechanical equipment, such as nuts, bolts, and other common threaded parts.
Advantages of ChaoYue CNC turning parts
Ensure the dimensional accuracy of the turned parts reaches the micrometer level, enabling complex geometric shape machining. The high degree of automation greatly improves production efficiency. It can process various metal and non-metal materials. When the material hardness is high, CNC turning can effectively process it by selecting hard alloy knives or other high-performance cutting tools. Processing engineering controls parts with high consistency through data engineering, improving product quality and reliability. Customized processing can be carried out according to customer needs to meet different shapes, sizes, and precision requirements.

Manufacturing process of CNC turning parts
There are mainly seven steps including design and planning, preparation of raw materials, programming settings, processing operations, quality inspection, surface treatment, packaging, and delivery
Quality Control of CNC Turning PartsStrictly control the selection of raw materials and properly store them, while conducting regular spot checks on inventory materials to ensure the stability of quality. Regularly maintain and calibrate the equipment during processing, rigorously inspect the first piece of each batch before mass production, and conduct regular inspections and sampling of a certain number of parts for testing during the mass production process to ensure production stability and quality consistency. Finished product inspection is mainly conducted through appearance, size, performance, and sampling inspection. For key dimensions, multiple measurements can be taken and the average value can be taken to improve measurement accuracy.
Common questions
