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. PTJ can improve production efficiency in the case of multi-variety, small-batch production, reduce the time of production preparation, machine tool adjustment and process inspection, and reduce the cutting time due to the use of the best cutting amount, providing users with a more timely delivery cycle, The fixture of the cnc machining center certainly contributed. 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 that its fixture is 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, batch size, machining cycle, and machining cost.
If you want to choose a good fixture reasonably, you must first have a deeper 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 that performs CNC turning machining is called a CNC 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 machining is the driving part of the CNC machine tool actuator, including spindle drive unit, feed unit, spindle motor and feed motor. He realizes the spindle and feed drive through the electric or electro-hydraulic servo system under the control of the numerical control device. When several feeds are linked, the machining of positioning, straight line, plane curve and space curve can be completed. Comprehensive consideration of various factors, choosing (xuanze) economical and reasonable fixtures can achieve a multiplier effect with half the effort, and can maximize the role of CNC machining centers.
