Engraving and milling machine:  
As the name suggests, it can be carved or milled. On the basis of the engraving machine, the power of the spindle and servo motor is increased, the bearing capacity of the bed is increased, and the high speed of the spindle is maintained at the same time. The engraving and milling machine is also developing at a high speed. It is generally called high-speed machine. It has stronger cutting capacity and very high machining precision. It can also directly process materials with hardness above HRC60. It is widely used in the industries of precision mold, mold kernel rough and fine machining, mold red copper electrode, batch processing of aluminum products, shoe mold manufacturing, fixture processing and watch eye environment. Due to high cost performance, fast processing speed and good finish of processed products, it plays an increasingly important role in machine tool processing industry  
CNC machining center:  
Hong Kong, Taiwan and Guangdong are also called computer gongs. The characteristics of machining parts on the machining center are: after the machined parts are clamped once, the NC system can control the machine tool to automatically select and replace tools according to different processes; Automatically change the spindle speed, feed rate of the machine tool, the movement track of the tool relative to the workpiece and other auxiliary functions, and continuously carry out multi process processing such as drilling, spot facing, reaming, boring, tapping, milling and so on. Because the machining center can centrally and automatically complete a variety of processes, avoid artificial operation errors, reduce the time for workpiece clamping, measurement and machine tool adjustment, as well as the time for workpiece turnover, handling and storage, and greatly improve the machining efficiency and machining accuracy, it has good economic benefits. Machining centers can be divided into vertical machining centers and horizontal machining centers according to the position of the spindle in space.  
Engraving machine:  
The torque is relatively small and the spindle speed is high. It is suitable for the processing of small tools. It focuses on the "engraving" function and is not suitable for large workpieces with strong cutting. At present, most products on the market under the banner of engraving machine are mainly for processing handicrafts, with low cost. Due to low precision, they are not suitable for mold development; Engraving and milling machine, machining center. In terms of index data of engraving machine, compare the maximum speed of spindle (R / min): Machining Center 8000; engraving and milling machine is the most common 240000, and high-speed machine is the lowest 30000; engraving machine is generally the same as engraving and milling machine, and the engraving machine used for highlight processing can reach 80000, but it uses air floating spindle instead of ordinary motorized spindle.
