CNC machining center and engraving and milling machine are very similar in appearance and structure. The abbreviation of numerical control lathe is an automatic machine tool equipped with a program control system. The control system can logically process a program with a control code or other symbolic instructions, decode it, express it with coded numbers, and input it into the numerical control device through an information carrier. CNC machining center is a highly automated multifunctional CNC machine tool (attribute: automated machine tool) with a tool magazine and automatic tool changer. 1. Conceptually the difference between CNC machining center and engraving and milling machine CNC machining center
CNC machining center: It is called computer gong in Hong Kong, Taiwan and Guangdong. It is a highly automated multifunctional CNC machine tool with tool magazine and automatic tool changer (attribute: automated machine tool). The first machining center appeared in the United States in 1958. It can realize the centralized processing of multiple processes such as milling, drilling, boring, reaming and tapping (tool: tap or tap) after the workpiece is clamped once, and the function is particularly emphasized; milling;. Engraving and milling machine: as the name implies. It can be engraved, milled, and engraved (the general term for the three creation methods of engraving, engraving, and plastic). The power of the spindle and servo motor (referring to how much work an object does in a unit time) is increased on the basis of the machine The bed can bear the force while maintaining the high speed of the spindle, and more importantly, the precision (precision) is high. Engraving and milling machines are also developing at a high speed, generally called high-speed machines, which have stronger cutting ability and very high machining accuracy. They can also directly process materials with a hardness above HRC60 for one-time forming. 2. In terms of appearance and volume, the difference between CNC machining center and engraving and milling machine CNC machining center has the largest volume. The large 1690 machine has a volume of 4m*3m, and the small 850 machine is also 2.5m*2.5m; However, the relatively large-scale 750 machine is generally 2.2m*2m; the engraving machine (the general term for the three creation methods of engraving, carving, and plastic) is the smallest. 3. The difference between CNC machining center and engraving and milling machine in terms of index data
Maximum spindle speed: machining center 8000; engraving and milling machines are the most common 240,000, high-speed machines are as low as 30,000; engraving (is the general term for the three creation methods of engraving, engraving, and plastic) is generally the same as engraving and milling machines, and is used for highlight processing. It can reach 80,000, but it is not a general electric spindle but an air-floating spindle. The abbreviation of Computer numerical control machine tools (Computer numerical control machine tools) is an automatic machine tool equipped with a program control system. The control system can logically process a program with a control code or other symbolic instructions, decode it, express it with coded numbers, and input it into the numerical control device through an information carrier.
Spindle power (referring to the amount of work done by the object in a unit time): the largest machining center, ranging from several kilowatts to tens of kilowatts; engraving and milling machines are the second, generally within ten kilowatts; carving (carving, engraving, The general term of the three creation methods) is the smallest machine. The abbreviation of Computer numerical control machine tools (Computer numerical control machine tools) is an automatic machine tool equipped with a program control system. The control system can logically process a program with a control code or other symbolic instructions, decode it, express it with coded numbers, and input it into the numerical control device through an information carrier.
Cutting capacity: Machining center is the largest, especially suitable for heavy cutting and roughing; engraving and milling machine is the second, suitable for finishing; engraving (the general term of engraving, engraving, and plasticizing) is the smallest.
Speed: Since engraving and milling machines and engraving machines (the general term for the three creation methods of engraving, engraving and plastic) are relatively light, their moving speed and feed speed are faster than machining centers, especially high-speed machines equipped with linear motors. Speed up to 120m/min
Accuracy (precision): The accuracy of the three is similar. The numerical control lathe sends out various control signals from the numerical control device after arithmetic processing to control the action of the machine tool, and automatically process the parts according to the shape and size required by the drawing. It has solved the problem of complex, precise, small batch and multi-variety parts processing. It is a flexible and high-performance automatic machine tool. It represents the development direction of modern machine tool control technology and is a typical mechatronics product. . The abbreviation of numerical control lathe is an automatic machine tool equipped with a program control system. The control system can logically process a program with a control code or other symbolic instructions, decode it, express it with coded numbers, and input it into the numerical control device through an information carrier.
