CNC machining capability is strong. After the workpiece is clamped at one time, it can complete more processing contents, and the machining accuracy is high. For batch workpieces with medium processing difficulty, its efficiency is 5 to 10 times that of ordinary equipment, especially it can complete many Processing that cannot be completed by ordinary equipment, so it can improve the processing accuracy of parts and stabilize the quality of products.
Whether the function can mainly meet the requirements of the machine tool. The general CNC system has two functions, the basic function and the selection function. The former is a function of the CNC system, and the latter is a function only provided when the user chooses, and a certain price will be added for each additional option. Therefore, in order to improve the economy of CNC machine tools, the functions of the CNC system must be carefully selected according to needs. The production preparation cycle is short, which is conducive to the replacement of mechanical products.
At the same time, due to the high precision of the CNC machine tool itself, the software can also be used for precision correction and compensation, and because it is automatically processed according to the CNC program, human errors can be avoided. Therefore, not only the machining accuracy is high, but also the quality is stable. Realize a variety of processing functions. Online machining is to connect the computer to the machine tool and process directly. In this case, in case of an accident, it is difficult to respond directly, only by pressing the emergency stop button. For the machining center, the determination of the placement position of the workpiece on the worktable should take into account the processing of each station, and the influence of the length of the tool and its stiffness on the processing quality should be considered.
Machining is a process of changing the dimensions or properties of a workpiece with a machining machine. According to the temperature state of the workpiece to be processed, it is divided into cold working and hot working. It is generally processed at room temperature and does not cause chemical or phase changes in the workpiece, which is called cold processing.
The processing economic accuracy of a certain processing method should not be understood as a certain value, but should be understood as a range, within which it can be said to be economical. Different processing methods, the axial rotation error of the spindle has little effect on the processing of the outer circle and the inner hole, but has a greater impact on the verticality and flatness of the processed end face. When threading, the spindle rotation error can cause periodic errors in the lead of the machined thread.
