The application of CNC mirror machining technology makes the metal surface roughness effect more ideal. For the mirror surface processed by CNC, its roughness is far less than 0.8um, which can reach 0.06, and the metal surface can reflect the image of the object more clearly. What’s more, the mirror machining efficiency of precision mold under the traditional technology is not high. The application of CNC mirror processing technology can effectively improve the processing efficiency of the mold. At the same time, CNC mirror processing technology can be used for mirror processing of raw materials of various materials, without too many limitations on the processing of raw materials. Although direct CNC mirror processing, the workpiece surface itself will always appear some knife marks, but in the later stage, there are subsequent processes of mold saving and polishing.
With time, when we are more proficient in the use of CNC mirror processing technology to cut metal, the surface roughness of machined parts will be lower, more in line with the desired finish, better applied to machinery. CNC lathe processing, is generally referred to in the CNC machine tool parts processing process. CNC machine tool is a kind of machine tool controlled by computer. The computer used to control the machine tool, whether it is a special computer or a general-purpose computer, is collectively referred to as the numerical control system. The motion and auxiliary action of NC machine tool are controlled by the instruction of NC system.
The instruction of CNC system is compiled by the programmer according to the material of the workpiece, processing requirements, characteristics of the machine tool and the instruction format (NC language or symbol) specified by the system. According to the program instruction, the CNC system sends operation or terminal information to the servo device and other functional components to control the various movements of the machine tool. When the processing program of the part is finished, the machine will stop automatically. Dongguan mold factory any kind of CNC machine tool, in its CNC system, if there is no input program instructions, CNC machine tools can not work.
The controlled actions of machining machine tools generally include the starting and stopping of the machine tool; the starting and stopping of the spindle, the change of rotation direction and speed; the direction, speed and mode of feed motion; the selection of cutting tools, the compensation of length and radius; the replacement of cutting tools, the start and close of coolant, etc.
At the beginning of CNC machine tool, aircraft parts with complex surface are selected as processing objects, which is the key to solve the problem of ordinary machining methods. The most important feature of NC machining is that the machine tool is controlled by perforated tape (or tape) for automatic processing.
Due to the different characteristics of aircraft, rocket and engine parts: the size of parts and components of aircraft and rocket is large and the profile is complex; the size of engine parts and components is small and the accuracy is high.
Therefore, the CNC machine tools used by aircraft, rocket manufacturing and engine manufacturing departments are different. In aircraft and rocket manufacturing, large-scale CNC milling machines with continuous control are mainly used, while in engine manufacturing, both continuous control CNC machine tools and point controlled CNC machine tools (such as CNC drilling machine, CNC boring machine, machining center, etc.) are used in engine manufacturing.
