What is the difference between an engraving machine and a CNC milling machine?

From the use of points, the engraving machine is mainly used for the carving of the plate, a large number of applications in the two-colour plate or acrylic carving, carving a depth of about 1mm ~ 3mm or so, in the sign, signage production is more common.From the mechanical construction, engraving machine spindle head equipped with a spring pressure nose, the role of the carving process is to flatten the thin plate below 3mm, at the same time as the carving spindle connected to the larger diameter of the motor through the belt, the rotational speed is larger, the carving out of the workpiece is smoother.Due to the carving machine using a longer tool, only suitable for doing a very small amount of cutting high speed carving process production.

　　If the carving and milling machine to do three-dimensional carving, although the drop is very large, but a large amount of feed, 200mm wide material can be completed at once.In addition, the engraving and milling machine can be flexible selection of tool diameter specifications and length, loaded with a fine knife to do fine work, loaded with a thick knife to do big work.

　　As the design of the engraving and milling machine focuses on heavy-duty loads, frame steel, Z-axis stroke, so not only can do small engraving machine process, but also high-speed cutting of thick plates, a feed amount of up to 20mm ~ 30mm, which is the engraving machine can not be done at all the process of manufacturing.In this sense, the engraving and milling machine can do both fine engraving, but also can do cutting and milling.
