Four basic principles to be paid attention to in the selection of fixture in Cnc machining center

Do you understand the four basic principles of Cnc machining center fixture that need attention in the selection of cnc machining center fixtures? For the cnc machining center, it is too important to choose a good fixture, because in the cnc machining center, the task of the fixture is not only to clamp the workpiece, but also to use the positioning surface in each direction as a reference, determine the zero point of workpiece programming. . The parts processed on the cnc machining center are generally more complicated. In a drinking clip, the parts should be rough milling, rough bore, fine iron and fine bore, and require a variety of knives, which requires the fixture to withstand both large cutting forces, it also meets the requirements of positioning accuracy. The automatic tool change of the processing center ( ATC] the function is determined that the bracket, position detection and knife-facing elements cannot be used during processing. The high flexibility of the processing center requires that the fixture is compact and simple than the ordinary machine tool. The tight operation is fast and accurate, and the auxiliary time is minimized. The operation is convenient, labor-saving and safe, moreover, it is necessary to ensure sufficient rigidity and be flexible and changeable. For those who need to operate the machining center every day, if they want to reasonably apply the fixture, they must first have a deeper understanding and mastery of the machining features of the cnc machining center, at the same time, we should also pay attention to the following problems: 1. Accuracy of machined parts: 2. Batch size: 3. Manufacturing cycle; 4. Manufacturing cost. According to the cnc machining center manufacturers, according to the cnc machining center machine tool features and processing needs, the commonly used fixture structure types are special fixtures and combined fixtures; Adjustable fixture and group clamp

Nowadays, the adoption of pcb rapid prototyping machine in cnc machining prototype service industry is quite common.
