The NC technology of thread turning tools has benefited from the common progress made in comprehensively improving the coating and material grade of turning tools. In addition, in terms of thread turning blades, people have carried out better structural design and achieved better numerical control technology of chip control. Despite these changes, manufacturing engineers tend to spend little time optimizing thread machining operations, viewing the thread machining process as a "" that cannot be continuously improved by robots transferring them from hp-rtm presses to automated milling units. Part of the contour blade in the figure can process a series of threads by penetrating different depths. The fineness of the pitch that the blade can process is determined by the size of the small end radius (not shown in the schematic diagram), and the thickness of the pitch that the blade can process is determined by the strength of the radius. Figure 1 in fact, the efficiency of thread processing can be improved through engineering design. The first step should be to understand some basic topics in thread machining. High requirements for thread turning CNC technology thread turning requirements are higher than ordinary turning operations

the machining center is divided into hard rail and wire rail according to the structure of the guide rail. Many people have heard of these two, but they are not very clear about their specific meaning and differences. Today, Wuhan Huayou CNC has sorted out their characteristics and differences for your reference. If you have other problems of the machining center, you can also directly consult us. Hard rail refers to the casting part in which the guide rail and the bed are integrated, and the guide rail is processed on the basis of the bed (that is, the guide rail is cast on the bed, and then processed after quenching and grinding). The bed with steel guide rail is not integrated with the guide rail, and its guide rail is nailed to the bed after processing. Generally, steel inlaid (some plastic coated) guide rails are used more in heavy-duty soft packaging into food protagonist blow molding machines under extraordinary circumstances, and attention should be paid to lubrication when using. The hard rail machining center is sliding friction during machining, which belongs to surface contact. The contact surface is large, the friction is large, and the moving speed is slow. When machining cast iron and steel castings, the cutting capacity is large, and the cutting force is large when designing the plastic mold, and the vibration is severe. At this time, the benefits of hard track appear

when the command value is sent to the position comparison circuit, if the workbench does not move and there is no feedback, the command value makes the servo motor rotate and drives the workbench to move. At this time, the detection element feeds back the actual displacement of the workbench, compares it with the command value in the position comparison circuit, and controls it with the difference obtained after comparison until the difference is eliminated, which is called closed-loop control. This control mode has the advantages of high precision and fast speed, but the debugging and maintenance are complex and high cost. It is generally used for large and medium-sized CNC equipment with high requirements for motion speed and precision. 3. The semi closed loop servo system does not detect the actual position of the workbench, but indirectly measures the rotation angle of the servo motor through the detection element connected with the servo motor, and then calculates the actual displacement of the workbench. This value is compared with the command value, and the difference is used to realize control. Since the workbench is not completely included in the control circuit, the error of the ball screw driving the workbench to move cannot be compensated. Therefore, it is called semi closed loop servo system. Semi closed loop servo system is between open loop and closed loop, with higher accuracy than open loop, easier debugging than closed loop, and lower cost. It is a widely used numerical control system
