On the first feeling of engraving machine and engraving and milling machine, it is not difficult to see that their worktables are different. The worktable of engraving machine is smaller than that of engraving and milling machine. If you further understand, you will find that the two types of advance cnc machines are actually different structures, but the working principle is roughly the same. They are driven by the X, Y, and Z axes, and controlled by the electronic controller. There are also great differences in use, which can be expressed as:
The engraving machine is mainly used for engraving plates. It is widely used in double-color plates or acrylic engraving. The depth of one-time engraving is about 1mm-3mm. It is widely used in signs and signs. From the perspective of mechanical structure, the design of the engraving machine is light, the X and Y axes move fast, the Z axis travel is short, and it is suitable for engraving 5mm-8mm materials. The engraving spindle head is equipped with a spring pressing nose, which is used to flatten the thin plate under 3mm during the engraving process. The engraving spindle is connected to a motor with a larger diameter through a belt, so as to increase the speed, so that the quality of the engraved workpiece is smoother. The engraving tool used is longer, with a length of about 15.9cm and a diameter of about 4.35mm. Due to design limitations, it is suitable for high-speed engraving process with very small cutting volume.
The engraving and cnc milling machine can be understood as both fine engraving, cutting and router milling. For example, for three-dimensional carving, although the drop is large, the 200mm wide material can be completed at one time, and the amount of feed at a time is quite large. The diameter of cutters available for engraving and milling machines ranges from 1mm to 16mm, and the cutter length is 50 to 80mm. We can use it flexibly, install thin knives to do fine work, and thick knives to do big work. Because the machine design focuses on heavy loads, the frame has high rigidity, and the Z axis stroke is large, it can not only be used as a small engraving machine, but also can cut thick plates at high speed. Crafting that cannot be done at all.
