Compared with independent machining centers and CNC lathes, turning and milling CNC machine tools also have the following advantages:
1. Reduce the production and manufacturing process chain of commodities and improve work efficiency
The turning and milling machine equipment management center can install a variety of unique CNC blades, new CNC blade arrangements, reduce tool change time, improve processing efficiency, and can complete all or most of the processing process at one time, thereby greatly shortening the production of goods Process chain. On the one hand, it can reduce the production and manufacturing auxiliary time caused by the change of the tooling and fixture, and also can reduce the manufacturing cycle and waiting time of the tooling and fixture, and can significantly improve the productivity. The quotation for custom metal fabrication is also more appropriate;
2. Reduce clamping frequency and improve machining accuracy
Reduce the frequency of card installation and prevent the accumulation of deviation caused by the conversion of precision positioning standards. In addition, most of the existing turning and milling machine tools have online monitoring functions, which can complete the online detection and precision control of important data and information in the entire manufacturing process, and improve the processing accuracy of the goods; the high-toughness overall machine design scheme improves the difficulty of drilling The processing capacity of raw materials.
When turning and milling, the CNC blade performs intermittent drilling, and all workpieces processed by raw materials can be short drilled, which is convenient for automatic chip removal. In addition, interruption of cutting can make the knife have enough cooling time, reduce the thermal deformation of the workpiece, and increase the service life of the CNC blade. Compared with traditional CNC lathes, the turning and milling speed is higher, the quality of drilling products is better, the cutting speed is reduced, the accuracy of thick-walled parts and slender parts is improved, and the quality of workpiece forming is high.
When the turning and milling machine is processing the workpiece, the rotation speed of the workpiece is relatively low, which can reasonably reduce the centripetal force of the workpiece, prevent the deformation of the workpiece, and help improve the machining accuracy of the part. In the turning and milling process, the large vertical feed can also be used to obtain precise laser cutting, and the roughness can be reasonably ensured. Turning and milling machine tools can complete workpiece processing by turning, milling, drilling, boring and other different methods, and can also clamp the workpiece at one time for multi-face machining routine tasks to ensure machining accuracy.
3. Reduce land occupation and save product cost
The compact, beautiful, and generous design scheme improves the utilization of internal space, makes maintenance more convenient, and enables customers to obtain greater satisfaction; although the cost of each milling machine is relatively high, due to the reduction of the manufacturing process chain, the cost of goods The need for mechanical equipment is reduced, the total amount of tooling and fixtures is reduced, the area of the production workshop is reduced, and the maintenance cost of mechanical equipment is reduced. Project investment and the overall fixed assets of production can reasonably reduce production and operation costs and management methods.
Since the drilling speed can be decomposed into the rotational speed of the workpiece and the rotational speed of the CNC blade, according to the mechanical properties of the structure, the same processing effect can be achieved by increasing the rotational speed of the CNC blade and reducing the rotational speed of the workpiece. This feature is especially reasonable for large steel castings, because reducing the burr rate of steel castings can eliminate vibrations caused by the change in the axial force or the cycle time of the axial cutting speed of the workpiece, thereby ensuring the stability of the drilling of the workpiece and reducing Deviation of workpiece processing.
