What is the similarity and difference between CNC engraving and milling machine and CNC engraving machine?

     

       The engraving and milling machine is a kind of CNC machine tool. It is a CNC machine tool that corresponds to a traditional engraving machine. They believe that the engraving and milling machine is a CNC milling machine for small tools, high-power, high-speed spindle motors. The advantage of the engraving machine is engraving. If the hardness of the machined material is relatively large, it will be difficult. The appearance of the engraving and milling machine can be said to fill the gap between the two. The engraving and milling machine can be engraved and milled. It is a high-efficiency, high-precision CNC machine tool. Sharp is an outstanding generation of engraving and milling machines and CNC engraving machines.




      Small CNC engraving machine: suitable for small high-speed spindle machining tools, the torque is relatively small, focusing on the engraving function, such as wood (wood processing, especially wood carving machine) board and two-color board, the hardness of the acrylic board is not high, the workpiece is not suitable Strong cutting. At present, most of the products of the engraving machine on the market are mainly processed crafts, and the cost is low. Due to its low precision, it is not suitable for mold development, but there are exceptions, such as wafer engraving machines.




      Maybe someone will have this problem. Is the engraving machine an engraving machine?

      The insiders told the author that people intuitively feel that the small format is an engraving machine, and the large format is an engraving machine, an engraving machine, or a router, or simply a large engraving machine. In fact, they are two different machines, but they work roughly the same way. They are driven by three axes of x, y and z and are controlled by an electronic controller.




      In addition, from the purpose of use, the engraving machine is mainly used for plate engraving, such as: woodworking engraving machine, engraving machine, aluminum plate engraving machine, four-axis, five-axis engraving machine engraving machine, engraving machine, relief engraving machine, CNC wood engraving machine, Engraving machines, tombstones, etc. It is widely used in two-color plates or acrylic engraving. The depth of engraving knives is about 1mm~3mm. The logos and signs used are more common. From the mechanical structure point of view, the spindle head of the engraving machine is equipped with a spring pressure nose, which is used to flatten the thin plate below 3 mm during the engraving process. At the same time, since the engraving axis is connected to the larger diameter motor through the belt, the speed is larger and the engraved workpiece is smoother. Due to the long tool used in the engraving machine, it is only suitable for high-speed engraving processes with low cutting ability.




     If the engraving machine is used for three-dimensional engraving, although the reduction is large, a large number of knives, 200mm wide material can be completed at one time. In addition, the engraving and milling machine has the flexibility to select the tool diameter and length specifications, slowly drying with a fine knife, and working with a thick shank. .


     Because the design of the engraving and milling machine is mainly focused on heavy loads, large steel frames and large Z-axis strokes. Therefore, it can not only make the technology of the small engraving machine, but also cut the high speed and feed rate of the plate, which can reach 20mm ~ 30mm at a time, which is a process that the engraving machine can't do. In this sense, engraving machines and milling machines can be finely engraved, and cutting, engraving and milling can be done.


     With its technical advantages and reasonable price, the engraving and milling machine has become an important machine tool for consumer electronics parts manufacturing, small precision mold manufacturing, hardware products, furniture manufacturing and other industries. In addition, CNC engraving machines have also been used in the fields of high-power LED aluminum substrates, craft gifts, metal electrodes, and metal eye frame processing.
