CNC engraving and milling machine and the primary difference between numerical control machining center

Nc milling machining center, the moving parts rigidity requirements very well moving parts require very good advantages: rigidity for heavy cutting; Disadvantages: due to the mobile part of the same large, at the expense of his machine flexibility, for small part and fast feed could do nothing. CNC engraving and milling machine: the moving parts require good rigidity moving parts with flexible rigidity for the former title, as less as possible, while maintaining a certain rigidity. Are compared advantages: small machining, precision is high. For soft metal for high speed machining; Disadvantages: due to the poor rigidity so impossible for heavy cutting. High speed cutting machine: the moving parts rigidity demands very good mobile section rigidity is better, and as light as possible. Advantages: can in a small amount of cutting ( Patients generally & phi; 10 flat knife, for 45 # steel ( 300). Deep depth to 0. 75 is good) ; Disadvantages: can play under the correct use of high efficiency, low cost, make the grinding quantity is very few. Incorrect use, can make the tool scrap pile up soon.
