Do you know the fixture in the
CNC machining center? For CNC machining center, it’s very important to choose good fixtures. Because in the CNC machining center, the task of the fixture is not only to clamp the parts, but also to make sure the zero of the parts programming on the basis of the location of each direction.
The parts processed by CNC are generally more complex. The parts in a drink clamping need rough milling, coarse , fine iron and precision bore, therefore they need various tools, which requires the fixture can bear large cutting force, but also need to satisfy the accuracy requirements. With the automatic tool, the support, position detection and tool components cannot be used in the process of the CNC machining. Since the high flexibility of the CNC machining center, the fixture need more compact and simple than ordinary machine, swift and accurate in action, try to shorten the time of operation, easy in operation, saving labor, safety, and it ensure sufficient rigidity and flexibility.
For workers in the machining center, firstly they should have a deep understanding of the processing characteristics of the CNC machining in order to use the fixture reasonably, at the same time, they should pay attention to the following issues:
-
The accuracy of the machined parts
-
The size of the batch
-
The cycle of the manufacturing
-
The cost of the manufacturing
According to the characteristics of the CNC machining center and the needs of processing, currently, the fixture types commonly in structure has special fixture, modular fixture, adjustable fixture and group fixture.
