Kunshan Duyang CNC introduction: What are the advantages of vertical machining centers?

In simple terms, vertical machining centers and engraving and milling machines are essentially milling type CNC machining equipment. They are completely different in terms of processing capacity and use occasions. The vertical machining center is equipped with a tool library and an automatic tool changing device, so that it not only has the milling processing ability, but also can drill, boring, reaming and tapping and other composite processing capabilities. In addition to milling, the carving and milling machine can only be carved, not as powerful as the former. Specifically, we can follow their respective processing characteristics:

1, the characteristics of vertical machining center

In simple terms, the vertical machining center is a kind of highly automated multi-function CNC machine tool with a tool library and automatic tool changing device. It is developed on the basis of CNC boring and milling machines. Mainly suitable for processing plate, plate, mold and shell complex workpiece. The biggest processing feature is that the workpiece can be installed once, through the tool library and automatic tool changing device to concentrate on the workpiece drilling, milling, boring, reaming, tapping and other processes for centralized processing.

2, carving and milling machine characteristics

Simply put, the engraving and milling machine is developed on the basis of the engraving machine. In order to achieve the ability of milling processing, on the basis of the engraving machine, the spindle diameter is strengthened, the power of the servo motor is increased, and the bearing capacity of the bed is increased, while maintaining the high speed of the spindle, so that it has the ability of carving and milling processing.

In addition to the essential difference between the two in processing capacity, the two also have essential differences in mechanical structure, use occasions, volume structure, and machine tool configuration.

3, from the mechanical structure comparison

Vertical machining centers generally adopt bed type structure and integral casting. The machine head moves up and down through the slide on the herringbone column, and the workbench part adopts the cross slide table mechanism, the spindle speed is generally between 8000r/min-15000r/min, and the spindle has high rigidity, which can not only carry out the workpiece finishing but also the roughing.

The carving and milling machine generally adopts the gantry structure, and the body is mostly welded by steel plates, with poor overall rigidity. The spindle speed is generally between 24000r/min-30000r/min, because of the poor rigidity of the body and the spindle, only small feed amount of finishing can be carried out;

4, from the application of comparison

The vertical machining center has high spindle rigidity because its body is cast as a whole. Suitable for the completion of large milling amount of workpiece or mold processing, for large molds and high hardness materials can also be rough or finish machining; Engraving and milling machine because of its overall steel plate welding, coupled with the rigidity of the spindle is poor, can only carry out small milling amount of finishing, suitable for copper, graphite, wood, two-color plate, acrylic plate and other hardness is not high plate processing.
