Similarities and differences between CNC engraving and milling machine and small CNC engraving machine

       CNCengravingandmillingmachine It is a kind of CNC machine tool. It is a CNC machine tool that corresponds to a traditional engraving machine. Most of them think that the engraving and milling machine is a CNC milling machine that uses small tools, high power and high speed spindle motors. The advantage of the engraving machine is in the engraving. If the hardness of the processing material is relatively large, it will not work. 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 or milled. It is an efficient and high-precision CNC machine tool. The Sylph engraving and milling machine is an outstanding masterpiece of CNC engraving and milling machine.

Engraving machine: Its high spindle speed is suitable for the processing of small tools. The torque is relatively small, focusing on the “engraving” function, such as wood (specially processed wood called wood carving machine), double-color board, acrylic board and other low-hardness boards, no Great for large workpieces with strong cutting. At present, most of the products on the market with the name of the engraving machine are mainly for processing handicrafts, and the cost is low. Due to the low precision, it is not suitable for mold development; however, there are exceptions such as wafer engraving machine.

Some people may have such a question, is the engraving and milling machine an engraving machine?

The insiders told the author that people intuitively feel that the small format is the engraving machine, and the large-format engraving and milling machine, or the engraving machine, the router, or the collective engraving machine. In fact, they are two types of machines with different structures, but the working principle is roughly the same. They are driven by three axes of X, Y and Z, and are controlled by the electronic controller.

In addition, from the purpose of use, the engraving machine is mainly used for engraving of plates, and is widely used in two-color plates or acrylic engraving. The depth of engraving is about 1mm~3mm, which is more common in the production of signs and signs. From the mechanical construction 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 3mm during the engraving process, and at the same time, because the engraving spindle is connected to the larger diameter motor through the belt, the rotation speed is large, engraving The resulting workpiece is smoother. Due to the long tool used in the engraving machine, it is only suitable for the high-speed engraving process with a small amount of cutting.

If you use a engraving and milling machine to make three-dimensional engraving, although the drop is very large, the amount of one-time infeed is very large, and the material of 200 mm width can be completed at one time. In addition, the engraving and milling machine can flexibly select the tool diameter specification and length, and install a fine knife to dry and work hard.

Because the machine design of the engraving and milling machine pays attention to the heavy load, the frame has large steel and large Z-axis stroke, so it can not only do the process of small engraving machine, but also cut the thick plate at high speed. The amount of one-time feeding can reach 20mm~30mm. It is a process that the engraving machine can't do at all. In this sense, the engraving and milling machine can be used for both fine engraving and cutting and boring.

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