Both CNC machining centers and engraving and milling machines are commonly used mechanical equipment, and there are similarities and differences between the two. It is difficult to have an accurate answer to the question that whether CNC machining centers are better than engraving and milling machine. They cannot be compared because they have different uses. We can only compare the pros and cons of the two in some small aspects.
The rigidity of the non-moving part of CNC machining center is very good, and the rigidity of the moving part is also very good, which can carry out heavy cutting. The non-moving part of the engraving and milling machine has good rigidity, and because the engraving and milling machine is required to be flexible, so the rigidity of the moving part of the engraving and milling machine is worse than that of the CNC machining center.
The requirement of CNC machining center on the speed of main shaft is generally 0 to 8000rpm. Although high-speed machining centers can reach very high speeds, engraving and milling machines require relatively higher speed as a whole. Engraving and milling machines require high-speed CNC systems. Its speed of main shaft is generally at 3000 to 30000rpm, and the speed of main shaft of some specific engraving and milling machines is higher than high-speed machining center.
CNC machining center is used to complete equipment processing of workpieces requiring a large amount of milling, and can perform heavy cutting. The engraving and milling machine is generally used for processing equipment of small cutting amount or soft metal, and it is commonly used for lettering.
In general, even if you have to compare the two, you can't tell the difference. For example, you cannot use the engraving and milling machine in heavy cutting, and the machining center is useless in the fine lettering. It can only be said that both have their own characteristics and the field of action, so they cannot be compared.
