Cnc Machining Thread Method

At present, in the thread processing of CNC machining centers, the most widely used thread milling method is the thread milling method. To further improve the processing quality of the thread milling method, it is necessary to grasp the tool application process in the thread milling method to ensure the reliability and accuracy of the programming scheme. , It is necessary to check the main points of the milling tool to avoid deviations during processing. In the actual thread milling process, it is necessary to control the first helix to ensure that the pitch meets the original requirements. If there is an error, it should be adjusted in time. During the inspection process of this process, milling is generally required. After the reverse retraction, you can use tools such as a steel ruler to check the first helix. In addition, the amount of cutting tool on the total back of the thread needs to be paid attention to. CNC machining personnel can obtain real-time adjustment data through accurate calculation of the pitch to ensure that the accuracy of the milling process meets the requirements. Another important point to pay attention to is the end of the final turning tool. Ensure that the retraction and parking are reasonable, which is conducive to the control of the thread after the retraction, so as to further adjust the accuracy. In the entire threading process, it is necessary to do a good job of control to avoid the phenomenon of random buckles during processing, which requires all-around supervision and control of the process and sequence of thread milling in production. All problems must be paid attention to, and every link should be controlled to ensure that the accuracy and efficiency of thread processing can meet the standard requirements. When applying the thread milling method, the relative force of the thread milling cutter is relatively small compared to other processing methods, so it is rare for the tool to be damaged. If the tool is damaged due to operational reasons, its solution is also very convenient and simple. Compared with the diameter of the machined hole, the diameter of the tool is smaller, and the broken part of the tool is also easy to take out from the workpiece. The tap rule is very different. The tap rule is continuous and uninterrupted cutting, and the force is relatively large, and the cut waste is not easy to be removed in the processing area, so the tool is prone to breakage. If CNC machining is to process larger apertures, this situation is easy to handle, while smaller apertures need to be processed by EDM, which is more troublesome. Compared with other processing methods, the thread milling method can effectively reduce the number of processing procedures and the number of tool replacements, and can greatly improve work efficiency. Since the thread milling cutter can meet the processing requirements of chamfering, reaming, threading, and other processes during processing, a tool can process the left and right threads well through the modification of the processing program, and can also adjust the tool through the operating system. The radius is set to perform large machining of internal and external threads. For CNC machining workpieces with large apertures, multiple pairs of blade cutters can be used, which can double the machining efficiency.
