The CNC machining center processes are concentrated, and the processed parts are generally more complex. The machining process requires a variety of tools. This requires the fixture to withstand large cutting forces and meet the positioning accuracy requirements. Due to the use of the best cutting amount, the cutting time is reduced, and the fixture of the cnc machining center is of course indispensable for providing users with a more timely delivery cycle. The task of the fixture is not only as simple as clamping the workpiece, but also the selection of the fixture for the CNC machining center.
The high flexibility of CNC four-axis machining center or five-axis linkage CNC machining center requires its fixture to be compact and simpler than ordinary machine tools, minimize auxiliary time as much as possible, convenient operation and control, labor-saving, safe, and ensure sufficient rigidity. Be flexible and changeable. When choosing a suitable fixture, attention should be paid to the accuracy of the processed parts, the batch size, the processing cycle, and the processing cost.
If you want to choose a good fixture reasonably, you must first have a deeper understanding of the processing characteristics of the CNC machining center. CNC machining tools for CNC milling are called CNC milling machines or CNC machining centers. The lathe that performs numerical control turning processing is called a numerical control turning center. The CNC machining G code can be programmed manually, but usually the machining workshop uses CAM software to automatically read the CAD file and generate the G code program to control the CNC machine tool.
CNC computer gong processing is the driving part of the CNC machine tool actuator, including spindle drive unit, feed unit, spindle motor and feed motor. Under the control of the numerical control device, it realizes the spindle and feed drive through the electric or electro-hydraulic servo system. When several feeds are linked, the processing of positioning, straight line, plane curve and space curve can be completed. Considering various factors comprehensively, choosing economical and reasonable fixtures can achieve a multiplier effect with half the effort and maximize the role of CNC machining centers.
