CNC machining CNC blades should be clamped firmly and not too short in the elastic chuck. Before each cable cutter, check whether the CNC machined cutter head meets the requirements. The cable cutter length should be established according to the in-depth manufacturing of the operation procedure sheet. Generally, it should be slightly better than the in-depth value of 2mm and the elastic clamp should be fully considered. Whether the head collides. When encountering a situation with a deep level of production and manufacturing, you can communicate and communicate with the program process writer, and use the method of two cable cutters as appropriate, that is, first obtain half to 2/3 of the length, and wait for the production to reach a deeper position. If it is longer, it can improve the production efficiency. When using additional sockets, it is especially necessary to grasp the data information such as the depth of the knife and the length of the knife. Before the CNC machining cutter head is installed and operated on the machine, its smoothness matches the position with a cleaning towel to wipe it clean and tidy. The relative position of the cutter sleeve of the machining center is also cleared to avoid the iron pins of the matching cloth from damaging the accuracy and damaging the machining center.
　　 The basic principle deviation of CNC machining is caused by the selection of similar machining motion modes or similar CNC blade contours. It is often called the deviation of the basic principle of processing, because there is a deviation in the basic principle of processing. If the basic principle deviation is within the permissible range, this type of solution is still feasible. Manufacturing deviations, installation deviations and damage in machine tool applications immediately endanger the processing accuracy of the product workpiece. Among them, the key is the rotational movement of the lathe spindle, the uniform linear movement of the machine tool guide rail and the deviation of the machine tool transmission gear. The key to the precise positioning deviation of CNC machining includes the relative error of standard misalignment and the manufacturing deviation of precise positioning. When processing a product workpiece on a machine tool, be sure to select several geometric features on the product workpiece as the precise positioning standard in the production process. If the selected precise positioning reference is inconsistent with the design plan reference, there will be a reference non-pointing deviation. The precise positioning of the product workpiece surface and the precise positioning of the tooling and fixture components together produce a precise positioning pair. The large part transformation of the product workpiece caused by the inaccuracy of the precision positioning pair's production and manufacturing and the mutual matching gap between the precision positioning pair is called the inaccuracy deviation of the precision positioning pair's production and manufacturing. The inaccurate manufacturing deviation of the precise positioning pair always occurs when the regression analysis method is selected, and it is not easy to appear when the tool radius compensation method is used.
