This knurled bushing is a typical CNC Turning Part made of black POM by Dongguan Shengpeng Precision Technology Co., Ltd. It has a cylindrical structure with smooth surface and evenly distributed rubbers. The top has a continuous hollow hole, while the side wall is equipped with a small screw machine, which gives a compact design and accurate dimensions. Thanks to the high rigidity, wear resistance and self-lubrication ability of the POM material, this bearing can operate stably for long periods of time without oil wear, thus effectively avoiding the usual rust problems of metal components.
Step 1: In the processing stage, we use high purity black POM rods as raw material. After precise cutting, the raw materials enter the CNC turning process, during which the unworked turning is carried out first on the CNC turning machine to effectively eliminate most of the excess and form the outer contour in steps and the structure of the inner central opening.
Step 2: Thanks to the precision machining process, , the admissions of key functions, such as the diameter of the inner opening and the size of the outer circle, are strictly controlled within ± 0.005mm to ensure coaxiality between the inner opening and the outer circle.
Step 3: Use turning tools or special knurling wheels to perform straight lines along the outer circle to ensure uniform and clear motifs and reliable slip protection. Our Precision CNC Turning Services optimize the cutting parameters (such as speed, feed and cooling strategy) for the thermal sensitivity and low loss properties of POM materials and effectively prevent thermal deformations during the machining process; At the same time, no further surface treatment is required, and the opaque black texture is preserved immediately after rotation, simplifying the process and ensuring product stability.
As a professional manufacturer of CNC machining services, Dongguan Shengpeng Precision Technology Co., Ltd. can offer an effective CNC machining service, whether the size, material exchange (e.g., aluminum alloy, stainless steel, POM, PEEK and other engineering plastics) or process change surface machining (e.g., sandblasting, galvanizing, coating, etc.), all can be performed upon request. Our Turning Services are widely used in precision tools, automation equipment and other industries to offer services from a single point of view, from construction verification to mass supply.
