1. Comparison in terms of mechanical structure
Vertical machining centers generally adopt a bed structure and are integrally cast. The machine head moves up and down on the herringbone column through a sliding plate, and the workbench part mostly adopts a cross sliding table mechanism. The spindle speed is generally between 8000r/min and 15000r/min, and the spindle rigidity is high. It can not only be used for precision machining of workpieces but also for rough machining;
The carving and milling machine generally adopts a gantry structure, and the body is mostly welded with steel plates, resulting in poor overall rigidity. The spindle speed is generally between 24000r/min and 30000r/min, and due to the poor rigidity of its body and spindle, it can only be processed with small feed rates;
2. Compare in terms of application scenarios
Vertical machining centers have a high spindle rigidity due to their integral casting body. Suitable for processing workpieces or molds with large milling quantities, and for large molds and materials with high hardness, rough or precision machining can also be carried out; The engraving and milling machine is made by welding the entire steel plate, coupled with the poor rigidity of the main shaft, and can only perform small milling amounts of precision machining. It is suitable for processing copper, graphite, wood, dual color boards, acrylic boards and other boards with low hardness.
