According to the customer's requirements, we carry out the preliminary machining of the handle on the CNC lathe, cutting out the basic shape and size of the handle. During the turning process, the CNC machine will precisely control the path of the tool, ensuring the diameter, length and geometry of the handle with high precision. Precision long threads are cut on the handle by CNC equipment or special thread machining equipment. After the thread is finished, it is inspected to ensure that the size and shape of the thread meet the standard.
