To put it simply, both vertical machining centers and carving and milling machines are essentially milling-type CNC machining machines. They are completely different from each other in terms of processing capability and usage. Vertical machining centers are equipped with tool magazines and automatic tool changers, making them capable of not only milling, but also drilling, boring, reaming, tapping and other compound machining. The engraving and milling machine, in addition to milling processing, can only carry out engraving processing, unlike the former as powerful. Specifically we can under their respective processing characteristics.
1.The characteristics of vertical machining center in simple terms.
Vertical machining center is a highly automated multifunctional CNC machine tool with tool magazine and automatic tool changer. It is mainly suitable for processing plate, disk, mold and shell type complex workpieces. The biggest processing feature is that the workpiece can be clamped at one time, through the tool magazine and automatic tool changing device to focus on the workpiece drilling, milling, boring, reaming, tapping and other processes for centralized processing.
2.The characteristics of the carving and milling machine in simple terms.
the carving and milling machine is based on the development of the carving machine. In order to achieve the ability of milling, on the basis of the engraving machine thickened the spindle axis diameter, increased the power of the servo motor, as well as increased the bearing capacity of the bed, while maintaining a high spindle speed, so that it has the ability to carve and milling processing. In addition to the processing capacity of the two have essential differences, the two in the mechanical structure, use occasions, volume structure, machine configuration also have essential differences.
3.From the mechanical structure of the vertical machining center is generally bed type structure, the overall casting.The head in the herringbone column through the slide plate up and down, the table part of the cross slide table mechanism, spindle speed is generally between 8000r/min-15000r/min, spindle rigidity is high, not only can be workpiece finishing can also be open rough machining; engraving and milling machine is generally used gantry type structure, the body is mostly welded steel plate, the overall rigidity is poor. The spindle speed is generally between 24000r/min and 30000r/min, which can only be used for finishing with small feeds due to the poor rigidity of the machine body and spindle.
4.Comparison in terms of application occasions.
Vertical machining center because of its body for the whole casting, spindle rigidity is high. If you need to complete a larger milling volume of workpiece or mold processing, for large molds and relatively high hardness of the material can also be open rough or finish machining, you can choose BORUI CNC vertical machining center, we add a small, medium, heavy machining center, but also according to user needs custom.
Carving and milling machine because of its overall steel plate welded together, coupled with the poor rigidity of the spindle, only a smaller milling amount of finishing, suitable for copper, graphite, wood, two-color plate, acrylic plate and other hardness of the plate processing.
