Engraving and milling machine ≠ engraving machine
In fact, since the development of machine tools such as machining centers, some people have questioned them in the machine tool industry. For example, the functions of machining centers are too full, and it is too expensive to process small products. In addition, in order to be able to process small products, The BT40 spindle of a machining center is generally required to reach more than 20,000r / min, which not only brings considerable difficulties to design and manufacturing, but also makes the use cost too high.
It is based on these considerations that some companies try to separate the function of processing small products from the machining center to form a new variety of machine tools. CNC engraving and milling machine came into being.
The birth of the CNC engraving and milling machine has made up for the lack of a single CNC machine (milling machine, drilling machine, etc.), while the machining center has a high cost for processing small products, and has provided a new type of machine tool with high cost performance for the development of China's manufacturing industry. Products are the new army in China's machine tool industry.
Maybe someone has such a question, is the engraving and milling machine the engraving machine?
People in the industry told me that people intuitively feel that the small format is the engraving machine, and the large format is the engraving and milling machine, or the engraving chisel, router, or simply the large 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, X, Y, and Z, and controlled by electronic controllers.
In addition, from the point of use, the engraving machine is mainly used for engraving plates. It is widely used for double-color plate or acrylic engraving. The depth of one infeed for engraving is about 1mm ~ 3mm. It is widely used in the production of signs and labels. From the perspective of mechanical structure, the main head of the engraving machine is equipped with a spring pressure nose, which is used to flatten thin plates below 3mm during the engraving process. At the same time, because the engraving spindle is connected to a larger diameter motor through a belt, the rotation speed is larger and the engraving is The resulting workpiece is smoother. Due to the long tools used in the engraving machine, it is only suitable for high-speed engraving with a small amount of cutting.
If you use a engraving and milling machine to do three-dimensional engraving, despite the large drop, the amount of feed is large at one time, and 200mm wide materials can be completed at one time. In addition, the engraving and milling machine can flexibly choose the diameter and length of the tool, install fine knives for fine work, and rough knives for big work.
Because the design of the engraving and milling machine focuses on heavy loads, the rigidity of the frame is large, and the Z axis travel is large, so it can not only be used for the process of small engraving machines, but also can cut thick plates at high speeds. It is a manufacturing process that the engraving machine cannot do at all. In this sense, the engraving and milling machine can do both fine engraving, cutting and engraving.
Engraving and milling machine has become an important machine tool in China's consumer electronics parts manufacturing, small precision mold manufacturing, hardware products, furniture manufacturing and other industries with its technical advantages and reasonable prices. In addition, in the fields of high-power LED aluminum substrates, craft gifts, metal electrodes, metal glasses frame processing, etc., CNC engraving and milling machines have also begun to be used.
