The volume of the machining center is very large. The size of large-scale 1690 machine is 4m3m, that of small-sized 850 machine is 2.5m2.5m, Yiming carving milling machine is the second, large-scale 750 machine is 2.2m2m, the smallest.
Starting the mechanical structure of the machining center, cantilever type, engraving milling machine large-scale industrial engraving machine are usually adopted. The long door structure is divided into beam type fixed beam type. At present, fixed beam residence is adopted for engraving milling machine.
Spindle speed (R / min): 8000 machining centers; 240000 are most commonly used in milling machines; 30000 are most commonly used in high-speed machine tools; engraving machines - usually the same as milling machines - can reach 80000 for high gloss processing, but this is an ordinary spindle, but a pneumatic spindle. Spindle power: the machining center is very large, ranging several thousand watts to dozens of kilowatts, followed by carving milling machines, generally within 10 kilowatts, engraving machines at least.
