What is the difference between a metal engraving machine and a 5-axis machining centre?

1. Difference in machining range between metal engraving and milling machine and machining center

Machining center in the processing of small molds with small tools will seem overwhelmed, and the cost is very high. The advantage of the engraving machine in the carving, if the processing material hardness is relatively large will also appear to be incompetent. The emergence of metal engraving and milling machine can be said to fill the gap between the two.

Machining center it can be realized after a workpiece clamping can be milling, drilling, boring, reaming and tapping and other processes of centralized machining, the function of special emphasis on "milling", machining centers on the CNC system requires speed in general, the spindle speed of 0 ~ 8000 RPM or so is particularly suitable for heavy cutting, rough machining centers generally use the Cantilever type, the volume is relatively large.

2. Metal engraving and milling machine and machining center structure difference

Metal engraving and milling machine generally use gantry type architecture, gantry type is divided into building beam type and fixed beam type, the current metal engraving and milling machine to fixed beam type majority. Can carve, can also be milling, engraving machine on the basis of increasing the spindle, servo motor power, bed bearing, while maintaining high speed spindle, more importantly, high precision. Metal engraving and milling machine also to high-speed development, generally known as high-speed machine, cutting ability is stronger, processing precision is very high, but also can directly process the hardness of the material above HRC60, a molding, suitable for finishing. Metal engraving and milling machine requires high-speed CNC system, spindle speed of about 3000~30000RPM.

CNC milling and machining centers are used to complete larger milling volume of workpiece processing equipment. CNC metal engraving and milling machine is used to complete smaller milling amount, or soft metal processing equipment. High speed cutting machines are used to complete medium milling volume, and minimize the amount of grinding after milling processing equipment.
