The difference between NC and CNC(3)

6. Linear Motor

In recent years, the performance and popularity of linear motors have been significantly improved, so many machining centers have adopted this device. So far, Fanuc has installed at least 1,000 linear motors. Some advanced technologies of GE Fanuc make the linear motor on the machine tool have a maximum output force of 15,500N and a maximum acceleration of 30g. The application of other advanced technologies has reduced the size, weight and cooling efficiency of the machine tool. All these technological advancements make linear motors have stronger advantages when compared with rotating motors: higher acceleration/deceleration rates; more accurate positioning control, higher stiffness; higher reliability; internal dynamic control move.

Additional external features: open CNC system

The development of machine tools using open CNC systems is very rapid. The communication speeds of the currently available communication systems are relatively high, so many types of open CNC structures appear. Most open systems combine the openness of a standard PC with the functions of a traditional CNC. The biggest advantage of this is that even if the hardware of the machine tool is outdated, the open CNC still allows its performance to change with the existing technology and processing requirements. With the help of other software, you can also add other functions to the open CNC. These properties can be closely related to mold processing or have little to do with mold processing. Under normal circumstances, the open CNC system used in the mold shop has the following commonly used function options:

Inexpensive network communication;

Ethernet;

Adaptive control function;

Interfaces for connecting barcode readers, tool serial number readers and/or pallet serial number systems;

The function of saving and editing a large number of part programs;

Storage program control information collection;

File processing function;

CAD/CAM technology integration and workshop planning;

General operation interface.

The last point is extremely important. Because mold processing requires more and more simple CNC. In this concept, the most important thing is that different CNCs have the same operation interface. Generally speaking, operators of different machine tools must be trained separately because different types of machine tools and machine tools produced by different manufacturers use different CNC interfaces. The open CNC system creates opportunities for the entire workshop to use the same CNC control interface.

Now, the owner of the machine tool can design his own interface for CNC operation even if he does not understand the C language. In addition, the open system controller allows different machine operation modes to be set according to individual needs. In this way, operators, programmers and maintenance personnel can set up according to their own requirements. When in use, only the specific information they need appears on the screen. Using this method can reduce unnecessary page display and help simplify CNC operations.

Five-axis machining

In the process of manufacturing complex molds, five-axis machining is becoming more and more widely used. The use of five-axis machining can reduce the number of tooling or/and machine tools required to process a part, and the number of equipment required for the machining process will be minimized, while also reducing the total machining time. CNC is becoming more and more powerful, which allows CNC manufacturers to provide more five-axis features.
