What are the differences between CNC machining centers and engraving and milling machines?

CNC machining centers and engraving and Milling machines are very similar in appearance and structure. The abbreviation for numerical control lathe is an automated machine tool equipped with a program control system. This control system is capable of logically processing programs with control codes or other symbolic instructions, decoding them, representing them in coded numbers, and inputting them into numerical control devices through information carriers. A CNC machining center is a highly automated multifunctional CNC machine tool with a tool magazine and automatic tool changing device (attribute: automated machine tool).

1. The difference between CNC machining center and engraving and Milling machine conceptually. CNC machining center

Carving and Milling machine: as the name suggests. On the basis of carving, milling, and sculpting (a general term for the three creation methods of carving, engraving, and shaping), the machine increases the power of the spindle and servo motor (referring to the amount of work done by the object per unit time), the load-bearing capacity of the bed, while maintaining the high speed of the spindle, and more importantly, the accuracy (degree) is very high. Carving and milling machines are also developing towards high speed, generally referred to as high-speed machines. They have stronger cutting capabilities, very high machining accuracy, and can directly process materials with hardness above HRC60, forming them in one go. 2. In terms of appearance and volume, the difference between CNC machining centers and engraving and milling machines is that the volume of CNC machining centers is 4m * 3m for large 1690 machines and 2.5m * 2.5m for small 850 machines; Next is the carving and milling machine, with larger 750 type machines generally measuring 2.2m * 2m; Carving (a general term for the three creative methods of carving, engraving, and sculpture) machine. 3. The difference between CNC machining centers and engraving and milling machines in terms of indicator data

Spindle speed: 8000 for machining center; Common carving and milling machines cost 240000 yuan, while high-speed machines cost 30000 yuan; Carving (a general term for the three creation methods of carving, engraving, and shaping) machines are generally the same as carving and milling machines. Carving machines used for highlight processing can reach 80000, but they do not use ordinary electric spindles but air floating spindles. The abbreviation for Computer Numerical Control Machine Tools is an automated machine tool equipped with a program control system. This control system is capable of logically processing programs with control codes or other symbolic instructions, decoding them, representing them in coded numbers, and inputting them into numerical control devices through information carriers.

Spindle power (referring to the amount of work done by an object per unit time): machining centers can range from several kilowatts to tens of kilowatts; Engraving and milling machines are second, generally within ten kilowatts; Carving (a general term for the three creative methods of carving, engraving, and sculpture) machine. The abbreviation for Computer Numerical Control Machine Tools is an automated machine tool equipped with a program control system. This control system is capable of logically processing programs with control codes or other symbolic instructions, decoding them, representing them in coded numbers, and inputting them into numerical control devices through information carriers.

Cutting quantity: machining center, especially suitable for heavy cutting and rough cutting; Next to carving and milling machines, suitable for precision machining; Carving (a general term for the three creative methods of carving, engraving, and sculpture) machine.

Speed: Due to the relatively lightweight nature of carving and milling machines, as well as carving (a general term for the three creation methods of carving, engraving, and shaping) machines, their movement speed and feed rate are faster than machining centers, especially for high-speed machines equipped with linear motors that can reach a movement speed of 120m/min

Accuracy (degree): The accuracy of the three is similar. The CNC lathe generates various control signals through computational processing by the CNC device, which controls the movement of the machine tool and automatically processes parts according to the required shape and size on the drawing. It effectively solves the complex, precise, small batch, and multi variety machining problems of parts, and is a flexible and capable automated machine tool that represents the development direction of modern machine tool control technology. It is a typical electromechanical integration product. The abbreviation for numerical control lathe is an automated machine tool equipped with a program control system. This control system is capable of logically processing programs with control codes or other symbolic instructions, decoding them, representing them in coded numbers, and inputting them into numerical control devices through information carriers.
