One, of numerical control machine tool form numerical control machine tool to be comprised by the following parts commonly (1) 1 seeing a picture. Lead plane the main body that this is numerical control machine tool, what basically point to is the lathe bed of the machine tool, pillar, main shaft and other and main mechanical part. What machine element according to cutting is different, lead plane can divide the machine tool that is all sorts of differring, like lathe, milling machine, drilling machine, sell a bed to wait a moment. From apparently look, the lead plane structure of numerical control machine tool and general accuracy machine tool have similar place, also can divide wait for main component part for lathe bed, pillar. But actually structure of lead plane of numerical control machine tool passes special design commonly. Because numerical control system is the equipment of high automation, the requirement that its structure must satisfy automation to produce, requirement that is like dynamic character, hot metabolic asks to wait a moment. So the lead plane structure of numerical control machine tool is a course greatly CAD is designed and get. 2. Numerical control system the core that this is numerical control machine tool. Include numerical control hardware (circuit board, monitor, clavier, memory) numerical control software two much. The numerical control system of machine tool of contemporary numerical control is to use computer pilot mostly, numerical control system has a few more following main function: Much coordinate is controlled () of much axis linkage; The interpolation of a variety of function; Of all sorts of process designing code change; Multiform data is inputted; All sorts of choices that machine means; Diagnose of breakdown oneself etc. Accordingly we call numerical control system CNC system. Because CNC system is the core of numerical control machine tool, accordingly the technical level of numerical control machine tool relies on the technical level of numerical control system greatly. And the crucial place that numerical control software is this core. Home already had proper motion of a lot of Technical Division to develop development to give numerical control software of Gao Shuiping now. In biennially " Chinese machine tool is exhibited " on we can see systems of all sorts of homebred Gao Shuiping numerical control. Such ability make the numerical control machine tool industry of our country had solid base. 3. Actuating device the drive component that this is actuator of numerical control machine tool. The drive electric machinery that basically includes each electric machinery of the main shaft driving unit, driving unit of each reference axis, main shaft, reference axis. The main shaft of general accuracy machine tool and feed system are will implement transmission and speed change by the gear of box of feed of electric machinery drive and main shaft box. And the main shaft of numerical control machine tool and feed motion are by numerical control the system issues a statement, through electric will come true with the movement of hydraulic pressure system. The actuating device that controls a machine tool with respect to logarithm so had a few special demands. Drive should have the servo that charges a machine tool than exactly the amount to answer ability goodly quickly, can dog accurate and acutely the statement that numerical control system issues. 4. The components of a few essential form a complete set that assisting what device points to is numerical control machine tool. The range that auxiliary unit includes is very wide, the electric, hydraulic pressure that included a machine tool to go up almost, pneumatic and the refrigeration related to machine tool treatment, defend, bits of lubricant, illume, platoon, series equipment. Because assist device to have very big effect to the function of the machine tool, their development is very so rapid. Of the auxiliary unit on the numerical control machine tool that our country manufactures now homebred change rate already very tall. 5. The machine tool that process designing machine charges to increase and increase of systematic function and process capability of numerical control machine tool as number assists device. Rise along with what a move in chess or a movement in wushu controls standard of machine tool technology, the much coordinate control of 3 above reference axis has become the standard of a lot of numerical control machine tools to configure. This kind of standard is configured to machining it is very important. And the to program that much coordinate machines is a more difficult issue. Take time of manual process designing is arduous, and the accuracy of the program is not tall. Such, use computer process designing to make the process designing way with indispensable machine tool of much coordinate numerical control. Microcomputer development is very rapid now, the process designing outside major opportunity can be finished on the microcomputer. But the part program of large and complex curved surface still must use small-sized computer to come true. Nearly ten years since, the function of numerical control machine tool had very great progress, size range of pipe bent and treatment object expand increasingly. So, the composition of numerical control machine tool also had a few change. Graph the composition that 1 middle finger gives is only, probably classification. Do not have friendly intercourse graph 1 in, what we can have understood numerical control machine tool roughly is basic make a case. 2, the machine tool that the machine tool of treatment characteristic numerical control of numerical control machine tool is automation of a kind of height, it is complex to solving model the treatment of face and high accuracy spare parts, the treatment of small lot spare parts, the treatment of complex part, have very important sense. Numerical control machine tool and photograph of general accuracy machine tool compare the advantage that having a lot of highlighting. Numerical control machine tool can finish a lot of general accuracy machine tool hard, the treatment of the complex part that perhaps can machine far from; Can raise the treatment precision of the spare parts greatly, stabilize the quality of the product; Can greatly improve productivity; Need special tool clamping apparatus scarcely, get used to the product treatment of much breed small lot; Reduce the amount in goods, expedite the flow of capital. Of course, numerical control machine tool also has earlier investment bigger, more advanced to operating the technical level of personnel to ask problem. Express the 1 contrast that showed numerical control machine tool and general accuracy machine tool. Choose and ought to use numerical control machine tool reasonably so, reduce manufacturing cost, in order to increase economic benefits and competitive capacity. The suitable scope of machine tool of nextpage3, numerical control is not all the part is used at CNC Machining, only certain part just applies to CNC Machining. The plan is machine tool of 2 specifications numerical control, special the scope of application with machine tool and respective general accuracy machine tool, graph the relation of the 3 treatment lot that showed all sorts of machine tools and cost. From the graph 2, graph 3 in we can see, numerical control machine tool applies to treatment the part with those are more complex and not large production lot. In the spare parts complex level considers, and special machine tool should be used to undertake machining when production lot is bigger. The spare parts that applies to CNC Machining has: (1) batch is small and the part that duplicates production for many times; (The part with 2) geometry complex form; (3) valuable spare parts is machined; (4) needs the part that examines entirely; (5) is other the spare parts that applies to CNC Machining. Use CNC Machining to afore-mentioned spare partses, play of ability utmost ground gives the characteristic of CNC Machining. CNC Machining technology is a newer course, it is the course with a very strong practicality. CNC Milling
