CNC Turning Services

Our CNC Turning Services have significant features of high precision and high efficiency. Relying on advanced CNC lathes, using high rigidity spindles and precision ball screw transmission systems, it can achieve micrometer level machining accuracy, with radial runout error controlled within ± 0.001mm and axial positioning accuracy of ± 0.002mm. Whether it is the turning of slender shaft parts or the processing of complex internal and external threads and conical surfaces, it can be accurately completed. At the same time, the automated processing greatly improves production efficiency, coupled with an automatic loading and unloading system, it can achieve 24-hour continuous operation, which is more than 50% more efficient than traditional lathe processing. For example, in the processing of automobile engine crankshafts, multiple processes are completed through one clamping, which not only ensures that the coaxiality error of each journal is less than 0.005mm, but also significantly shortens the production cycle, meeting customers’ demand for rapid delivery of bulk products.

Material selection for CNC Turning

In terms of material selection, we have a rich and widely adaptable material system. Metal materials include various types of carbon steel, alloy steel, stainless steel, aluminum alloy, copper alloy, titanium alloy, etc. Carbon steel and alloy steel are commonly used to manufacture mechanical transmission components, such as shafts, gears, etc., and meet mechanical performance requirements with their good strength and toughness; Stainless steel, with its excellent corrosion resistance, is suitable for component processing in fields such as food, chemical, and medical; Aluminum alloys and copper alloys are widely used in electronic and electrical product components due to their excellent cutting performance and thermal conductivity; Titanium alloy has become a key material in high-end fields such as aerospace and deep-sea equipment due to its high strength, low density, and excellent high temperature resistance. In addition, we can also process non-metallic materials such as engineering plastics and ceramics, such as polytetrafluoroethylene and zirconia ceramics, to meet the special performance requirements of different industries for materials. All materials undergo strict incoming inspection, and their performance is ensured to meet standards through methods such as spectral analysis and hardness testing.

The production process of CNC Turning

We have developed a scientifically standardized CNC Turning Services production process. Firstly, the technical team uses professional CAD/CAM software for process planning and programming based on the drawings or design requirements provided by the customer, generating accurate CNC machining programs. Next, the operator clamps the raw material onto the chuck or tip of the CNC lathe, and precisely sets the tool compensation parameters through the tool presetter to ensure the accuracy of the machining starting point. During the turning process, the real-time monitoring system built into the machine tool dynamically monitors key parameters such as cutting force, spindle speed, and feed rate. Once the parameters are abnormal, the system automatically alarms and adjusts the machining parameters to prevent tool wear and part scrap. For parts with high precision requirements, rough machining, semi precision machining, and precision machining are usually used in stages to gradually remove materials and ensure dimensional accuracy and surface roughness. After processing, post-processing steps such as deburring, cleaning, and rust prevention will also be carried out to ensure that the product meets delivery standards.

Surface treatment of CNC Turning

We provide diverse and professional surface treatment processes to enhance the functionality and appearance quality of our products. For metal parts, common surface treatments include electroplating, blackening, anodizing, spraying, etc. Electroplating processes such as chrome plating and zinc plating can enhance the surface hardness, wear resistance, and rust prevention ability of parts, while giving them a shiny metallic texture; Blackening treatment can form a dense oxide film on the surface of steel parts, effectively improving their corrosion resistance; Anodizing is commonly used for aluminum alloy parts, which not only enhances corrosion resistance but also achieves rich color effects through dyeing; The spraying process adopts electrostatic spraying or powder spraying, which can evenly adhere the coating, provide good protection for the parts, and achieve diversified appearance designs. For non-metallic material parts, we use methods such as polishing, grinding, and coating with special coatings to improve surface smoothness and functionality. Based on the product’s usage environment and customer needs, we will customize the most suitable surface treatment solution to ensure that the product’s performance and appearance are balanced.

Dimensional Inspection of CNC Turning

In the dimension inspection process, we are equipped with advanced testing equipment and a professional quality inspection team to implement strict and precise quality control. High precision roundness instruments can be used to detect roundness errors in shaft parts, with a measurement accuracy of up to 0.0001mm. Contour instruments can accurately measure the surface contour shape of parts, ensuring the machining accuracy of complex surfaces; The three coordinate measuring instrument can measure the three-dimensional dimensions of parts, quickly obtaining dimensional data of various parts, with a measurement accuracy of 0.001mm. We strictly follow the ISO 9001 quality management system standard, conduct sampling inspection on each batch of products, and perform full inspection on key components. During the inspection process, if any dimensional deviation is found to exceed the tolerance range, the quality traceability program should be immediately initiated to analyze the problems in the machining process, adjust machining parameters or replace cutting tools, and reprocess until the product is qualified, ensuring that every delivered product meets high-quality standards.
