The processing quality and processing efficiency of the thread directly affect the processing accuracy of the horizontal machining center and the vertical machining center. Thread processing is one of the applications that reflects the quality of machining centers. The following introduces several methods that can make the machining center have higher precision and more stable performance when processing threads. Horizontal machining centers and vertical machining centers have many methods for thread cnc machining, such as tap processing and milling processing. The correct selection of processing tools and the application of correct methods can improve the processing efficiency of the processing center.
A long time ago, the processing of taps used flexible tapping methods, and their structure was more complicated. In recent years, horizontal machining centers and vertical machining centers have been born. The performance of machining centers has gradually improved. The processing of taps has changed from flexible to rigid. Rigid machining is currently the main processing method of machining centers. When processing a kind of workpiece, first determine the threaded bottom hole, which has a great influence on the processing quality of the workpiece of the machining center. When selecting the workpiece of the horizontal machining center, you must choose different taps according to different workpieces in advance. Different tools require different tools for different workpieces, and the resulting performance is also different. Secondly, we should pay attention to the difference between through hole taps and blind hole taps.
When processing the workpiece, there will be a delay when the spindle starts, so as to ensure that the spindle reaches the predetermined speed. When retracting the tool, the hand-grinding tool adopts the spindle orientation to allow the tool to move radially, because the hand-grinding tool is not generally not very symmetrical, so be extra careful. The tool holder must be made accurately, otherwise it will cause random snapping.
