Comparison And Difference Between CNC Machining Center And CNC Engraving Machine
The machining center is a CNC milling machine, also known as a CNC machining center, while the engraving machine is generally considered to be a CNC milling machine that uses small tools, high power and high speed spindle motors. But in fact, there are differences between the two, each has its own advantages and disadvantages, all belong to the mainstream CNC processing equipment, and have applications in mobile phone 3D glass processing technology. Today, we use a table to understand the difference between the two, including appearance, spindle, cutting volume, application range, price and so on.
1, Machining Center
The machining center is a CNC milling machine, also known as a CNC machining center. It is an automatic processing equipment developed on the basis of general milling machines, generally refers to CNC milling machines with tool magazines.
CNC machining centers have developed rapidly in China, especially in South China and East China. According to statistics, the number of CNCs used to process mobile phone casings every year is on the order of hundreds of thousands, and the market is huge!
2, Carving Machine
In 2007, China's fine carving machine industry production capacity has exceeded 10,000 units / year, and the output value exceeded 1.5 billion RMB. At present, the production of fine carving machines is mainly dominated by four major sectors: Guangdong, Beijing, Jiangsu and Zhejiang.
The engraving machine is a kind of CNC machine tool.
Can be accurately carved or milled. On the basis of the engraving machine, the spindle and servo motor power and the capacity of the machine body are increased. At the same time, the spindle is kept at a high speed, and more importantly, the accuracy is high. It is generally considered to be a CNC milling machine that uses small tools, high power and high speed spindle motors.

Third, the comparison between machining center and carving machine
The machining center is generally based on milling, with the advantages of high machining precision and high degree of production automation. However, there are still some shortcomings, especially when machining small molds with small tools, the process control is inconvenient and the cost is high. The appearance of the carving machine can be said to make up for the short board of the machining center. And it can be engraved or milled. It is a high-efficiency and high-precision CNC machine tool.
The specific comparison between the two is shown in the table below.
Table: Comparison of machining center and engraving machine
|No||Project||.Machining Center||Carving machine||Remarks|
|1||Appearance volume||According to the difference of X/Y axis stroke: X stroke 1.6m, Y stroke 900 model (T1690) volume is 4m*3mX stroke 0.8m, Y stroke 0.5 model (T850) volume is 2.5m*2.5m||Definition by manufacturer: The largest size of the general engraving machine: 1.8m * 1.8m minimum size: 1.4 * 1.5m||Volume and weight, related to the amount of equipment cut|
|2||Spindle power and speed||The spindle of the machining center has a large power, generally 6.5kw (36,000 rpm) and up to tens of kilowatts.||The power of the engraving machine is the largest for machining hard materials such as stainless steel (6.5kw/36000 rpm). The minimum power is 1.2kw/60000 rpm (for glass engraving machine).||The higher the power, the greater the cutting force and the cutting amount. The higher the power, the smaller the rotation speed.|
|3||Cutting amount||Large cutting capacity, suitable for heavy cutting, suitable for roughing, used for mold processing||The cutting amount is second to the machining center, and the rough milling is suitable for finishing machining with higher precision and suitable for fine parts processing.|
|4||Application range||Large mold, hardness comparison material, common mold opening||Finishing: copper, graphite, 3C hardware, ceramics, sapphire, precious metals, etc.|
|5||Number of spindles||Single axis||Single/double/three/four axes||The more the number of spindles, the more clips are produced at one time, and the higher the efficiency|
|6||Price positioning||25~100w or more||10w~40w||Under normal circumstances, the engraving machine is priced lower than the machining center. Because the machining center only operates on a single axis and the price is high, it is now being replaced by the engraving machine.|
