The numerical control light pole processing technology ( 2)

What is a traditional CNC machining is done with manual operation general machine tools, processing with dynamic mechanical hand tool cutting metal, rely on the eyes with a caliper tool such as the precision of the measurement products. Modern industry already use computer digital control machine tool for

what is a traditional numerical control processing is done by hand using ordinary machine tool. In the process of machining, metal with mechanical tools manual cutting, the precision of product with eyes, caliper, and other tools to measure. Modern industry for a long time using computer numerical control machine tool operation. Numerical control machine can according to the technical staff in advance to prepare the program automatically processing any products or components directly. This is what we call. Nc machining; 。 Nc machining is widely used in the areas of mechanical processing, but also to the development trend of mould processing and is important and necessary technical means. ； Numerical control; It is the abbreviation of computer numerical control in the English language. Nc machine tools based on preprogrammed machining program automatically processed parts. We prepare the processing craft route, process parameters and tool motion trajectory, displacement, cutting parameters ( The spindle revolutions, feed rate, back to rate, etc. ) 。 ) And the auxiliary functions ( Tool change, spindle positive rotation, reverse rotation, open and close cutting fluid, etc. ) In accordance with the instruction code and program format prescribed by the nc machine tools, machining into a single program, and then record the contents of the program list in the control medium ( Such as punched tape, tape, disk, magnetic bubble memory) Then type nc machine tool numerical control device, thereby command to 0 + parts running of the machine. From the part drawing analysis to control the whole process of production of medium called compiled nc program. CNC machine tools and the difference between conventional machine tools, CNC machine automatic machining parts according to the program, and ordinary machine tools need to operate. As long as we change the process of controlling the movements of machine tools, we can achieve the purpose of processing different parts. Therefore, numerical control machine is especially suitable for processing complicated shape and high accuracy requirement of small batch parts. Machining parts because of nc machine tools must be according to the program, the programmer after the compiler, the input to the numerical control device to command in the machine tool. The input of the program is by controlling the media. Development trend of the application of numerical control technology not only bring revolutionary change to the traditional manufacturing, manufacturing as the symbol of the industrialization, and with the continuous development of numerical control technology and application in the field of expanding, in the defense, automotive and other international important industry of the people's livelihood is playing an increasingly important role in development. These industries equipment digitization has become a trend of modern development, such as: bridge three coordinates, and five coordinate high-speed CNC gantry milling machine, gantry five coordinates communication angular three coordinate nc milling planer, gantry CNC gantry milling machine, etc. Rapid development of the

as the core processor, the improvement of the performance of the numerical control system is of high speed machining center of feed speed of up to 80 m/min, empty running speed can reach 100 m/min. Many car factory in the world, including China's Shanghai general motors, has been part of high speed machining center production line to replace the modular machine tool. Cincinnati, super high speed machine tool the largest feed speed of 60 m/min, the maximum speed of 100 m/min, the acceleration of 2 g, the spindle speed is 60000 RPM. Processing a thin walled aircraft parts only need 30 minutes, and on ordinary high speed milling machine processing the same parts need 3 hours, need eight hours on the ordinary milling machine.

due to the organization of the specialization of each component, under the professional development of spindle factory, high-speed spindle is becoming more and more popular. In the past, only the model used in the automotive industry ( More than 15000 RPM model revolutions per minute) To become the necessary mechanical products.
