Future development of numerical control machine tool for CNC turning and milling
1:Two high speed, high precision speed and accuracy are 1 important indicators of CNC machine tools, it is directly related to the processing efficiency and product quality.
At the same time, the large scale integrated circuit and multi processor structure are adopted to improve the system's data processing capability, which is to improve the speed and accuracy of the interpolation operation.
In order to meet the requirement of high speed machining, CNC machine tool structure with the spindle motor spindle and be made one, realize frequency conversion motor and machine tool spindle bearing spindle motor integration, using magnetic bearings, hybrid bearings or ceramic rolling bearings and other forms. At present, ceramic cutting tools and diamond coated tools has been applied.
2.CNC machining plant, equipped with multifunctional automatic tool changer (tool storage capacity of up to more than 100) of all kinds of machining center milling can be realized at the same time, in the same machine boring, drilling, turning, reaming, reaming, tapping and other machining processes, modern CNC machine tools also uses multi spindle, polyhedron cutting, and the different parts of a part for cutting in different ways.
CNC system due to the use of multi - CPU structure and hierarchical interrupt control mode, you can be a machine tool on the simultaneous processing and programming, to achieve the so-called "foreground processing, background editing".
In order to meet the requirements of the flexible manufacturing system and computer integrated system, the numerical control system has a long distance serial interface, and can be connected to the data communication between the numerical control machine tool, and it can also be directly controlled by the number of numerical control machine tools.
