In mechanical manufacturing, numerical control equipment often plays a very important role, which is mainly CNC engraving machine and CNC engraving and milling machine. There are many customers who can't tell the difference between the two devices and mistakenly think that they are the same. However, as the CNC engraving machine and CNC engraving and milling machine are only one word apart, and their working principles are basically the same, but in fact, they are two different types of machines with different structures. Next, we will introduce the differences between them.

1, use
CNC engraving machine is mainly used for engraving of plates. It is widely used in double color plate or acrylic engraving. The cutting depth of engraving is about 1mm-3mm. It is widely used in signs and labels. From the aspect of mechanical structure, the design of CNC engraving machine is light, x-axis and y-axis move fast, z-axis travel is short, which is suitable for engraving 5mm-8mm materials. The engraving spindle head is equipped with a spring pressing nose, which is used to flatten the sheet under 3mm in the engraving process. The carving spindle is connected to a motor with a larger diameter by a belt, so as to increase the rotation speed, so that the quality of the carved workpiece is relatively smooth. It uses a longer carving tool with a length of about 15.9cm and a diameter of about 4.35mm. Due to the limitation of design, it is suitable for carving with small cutting amount and high speed.

2, function
Carving and milling machine can be understood as not only fine carving, but also cutting and milling. For example, for three-dimensional carving, although the drop is very large, the material with a width of 200 mm can be completed at one time, and the amount of feed at one time is quite large. The diameter and specification of the cutter available for the engraving and milling machine are 1mm-16mm, and the length of the cutter is 50-80mm. We can use it flexibly. We can install a fine knife to do fine work and a thick knife to do big work. Because the machine design pays attention to the heavy load, the frame is rigid, and the z-axis travel is large, so it can not only be used as a small CNC engraving machine process, but also cut thick plates at high speed, with a feed amount of 20 mm-30 mm, which is a process manufacturing that the CNC engraving machine can not do at all.

The birth of CNC engraving and milling machine makes up for the single processing function of general CNC machine tools (milling machine, drilling machine, etc.) and the high cost of processing small products in machining center. It provides a new type of machine tool product with high cost performance for the development of manufacturing industry in China, and it is a new force in machine tool industry in China.
