CNC machining center processes are concentrated, and the processed parts are generally complicated. The machining process requires a variety of tools, which requires the fixture to withstand both large cutting forces and positioning accuracy requirements. As a company that offers Automatic Lathe Machining Service, we believe that the task of the fixture is not only to clamp the workpiece, but the selection of the CNC machining center fixture is critical.
The high flexibility of the CNC four-axis machining center or the five-axis linkage CNC machining center requires that the fixture be compact and simpler than the ordinary machine tool, minimize the auxiliary time, make the operation control convenient, labor-saving, safe, and ensure sufficient rigidity. Be flexible and changeable. Choosing the right fixture should pay attention to the precision, batch size, processing cycle and processing cost of the machined parts.
In order to properly select the fixture, we must first have a deep understanding of the machining characteristics of the CNC machining center. CNC machining tools for CNC milling are called CNC milling machines or CNC machining centers. The lathe for CNC turning is called the CNC turning center. CNC machining G code can be programmed manually, but usually, the machining shop uses CAM software to automatically read CAD files and generate G code programs to control CNC machine tools. CNC computer processing is the driving part of CNC machine tool actuators, including spindle drive unit, feed unit, spindle motor, and feed motor. He drives the spindle and feeds through an electrical or electro-hydraulic servo system under the control of a numerical control unit. When several feeds are linked, the positioning, straight line, plane curve, and space curve can be processed.
