Difference between CNC milling machine, CNC machining center and CNC router

What are the differences in CNC milling machine, CNC machining center and CNC router? I believe that many people will be confused about this problem and they don’t know much when buying mechanical equipment. They don’t know how to distinguish, what kind of equipment should be purchased to meet their needs. Today, we will tell you the difference between the three CNC machines.

CNC millining machine

On the basis of engraving machines, the power of the spindle and servo motors increases, and keeps the bearing capacity of the bed while maintaining the high speed of the spindle. The CNC milling machine is also developed at high speed. It is often referred to as a high speed machine. It has stronger cutting capacity and very high machining accuracy. It can also use hardness to hardness, once, widely used in precision molds and molds, batch processing mold copper electrodes, aluminum products, shoes mold, fixture processing, and observation and eye Production. Due to high cost, fast processing, the good end of processing products, it plays an increasingly important role in the machine tool processing industry.

CNC machining center

The processing center processing parts is: After the workpiece clamps, the CNC system can control the machine to automatically select and replace the tool according to different processes; automatic replacement machine spindle speed, feed and tool movement path relative to workpiece and other auxiliary functions It automates multiple processes that automatically perform drilling, counters, hinges, drilling, mining, and milling. Since the machining center can complete various processes in a centralized and automated manner, it avoids human-machine operation error, reduces the time of workpiece clamp, measurement, and machine adjustment, and workpiece turnover, processing and storage time is greatly improved. Processing efficiency and processing accuracy, there is a good economic benefit. According to the position of the spindle in the space, the machining center can be divided into a vertical machining center and horizontal machining center.

CNC router

The torque is relatively small, the spindle speed is high. It applies to handling small tools. It focuses on the “routing” function, which is not suitable for large workpieces with powerful cutting. Most CNC routers are mainly used for processing crafts and low cost. It is not suitable for mold development due to low precision. Comparison of milling machines, machining centers and CNC router index data. Maximum spindle speed (r / min): The machining center is 8000, CNC milling machine is 240,000, the high speed machine is 30,000, the CNC router is usually the same as the milling machine, but the advanced CNC router can reach 80,000, but it does not use it universal electric spindle, but air float Spindle.

Spindle strength

The machining center is the largest, from thousands of watts to dozens of kilowatts; CNC milling machine is next, generally within 10 kW; the engraving machine is the smallest. Cutting amount: The machining center is the largest, especially suitable for heavy cutting and roughing; CNC milling machine is second, suitable for finishing; CNC router is minimal.

Speed

Since the CNC milling machine and the CNC router are relatively light, their movement speed and feed speed are faster than the machining center, especially with a high-speed machine with a wired motor, can be moved to 120 m / min.

Accuracy

The accuracy of the three machines is similar.

Application

The machining center is suitable for high-precision and large dimensional workpiece processing. Large molds and materials with relatively high hardness are also suitable for rough common molds. The CNC milling machine is suitable for workpieces with small machining dimensions, especially suitable for processing molds, suitable for metal materials. Copper plants, graphite and other processing; CNC routers are biased toward wood, two-color plate, acrylic plate, etc., high-end, high end suitable for polishing of wafer, metal shell, etc.

Difference between three CNC machines

The CNC machining center is used to complete a larger milling volume of processing equipment.

The CNC milling machine is used to complete a small amount of milling or soft metal processing equipment.

The CNC router is used to complete the amount of media milling and reduce the amount of abrasive after milling to minimize processing equipment.
