The price of precision CNC processing _ precision machinery processing factory

High precision CNC processing the making price? General cost? After the high precision CNC machining workpieces, common problems the following: 1, after the whole batch of workpiece processing, should check tool, cutting tool compensation value, make the program process, reference point web page, to adjust the card sample processing cutting tool, cutting tool compensation value exactly; In the loop when using tool, should be on the instrument against the knife to knife again, reducing the reasonable tool damage to machining harm; 2, removing the tool from the nc cutter, according to adjust the card or procedure process, clear code into a library. Hard disk and processing technology, complete equipment of cutting tool adjusting card into the library; Some 3, removing the jig, jig should record installation position and direction, and make a record and archiving; 4, will the ordinate stopped in the middle parts; 5, such as to standby at this moment, can press on the control panel of snap button switch power supply, a little wait, make the main shaft bearing in the spindle bearing water cooling oil as part of the flow can be automatically switch machine after back. High precision CNC processing new basic theory, a new principle, new assertion, new ways and new technology application in the application of ultra precision machine tools. Basic yuan in recent years, ultra high precision components such as level and structure of the machine bed using some new basic theory, a new principle, new assertion, new methods and new technology application. In the numerical control lathe structure level in order to improve just degree of ultra precision machine tools, static and dynamic bending rigidity, some of the ultra precision machine tool selection is very unique structure, such as triangular diamond pillar type structure of ultra-precision grinding machine is so huge straight through ( φ400毫米) Heavily sb-doped silicon grinding processing design, change the traditional gantry structure under heavy processing load is very easy to cause back down and the deflection deformation defects. In recent years to choose more playability series numerical control lathe structure, further expand the bending rigidity of nc lathe. Precision parts processing process monitoring roughing main consideration is the surface excess margin for quick removal. In the process of automatic processing machine tool, according to the set of cutting parameter, cutting tool according to the predetermined cutting trajectory automatic cutting. When the operator should be paid attention to by observation of cutting load table automatic processing in the process of cutting load changes, according to the strength of the cutting tool state, adjust the cutting dosage, exert the maximum efficiency of machine tool. Cutting depth. In machine tool, workpiece and tool rigidity permission, t is equal to the machining allowance, it is an effective way to improve productivity. In order to guarantee machining accuracy and surface roughness of the parts, general should leave a certain allowance for finish machining. CNC machine finish machining allowance can be slightly smaller than the ordinary machine tool chip breaking and chip removal performance is good. Nc machining, the chip breaking and chip removal is not like ordinary machine tool processing timely by artificial processing, chip easy winding on the cutter and workpiece, can damage the knives and cut the workpiece machined surface, even hurt and equipment accidents, affects the processing quality and the safe operation of machine tool, cutter has good chip breaker is required and chip removal performance. Cutting tool choice is in the numerical control programming of human-computer interaction condition. Should be based on the processing capacity of the machine tool, workpiece material performance, processing operations, cutting dosage, and other related factors selection tool and the handle correctly. The general principles of cutting tool choice: easy to install, good rigidity, durability and high precision. Under the premise of meeting the processing requirement, to choose a shorter handle as far as possible, in order to improve the cutting tool machining rigidity. Precision machining cutting tool selection and cutting dosage determined in nc machining is done in human-computer interaction conditions, this was in sharp contrast with ordinary machine tool processing, also requires programming staff must master the cutting tool selection and the basic principle of cutting parameter to determine, when programming in full consideration of the characteristics of nc machining, correctly choose the blade and cutting parameter. Nc machining tool must adapt to CNC machine characteristics of high speed, high efficiency and high degree of automation, generally should include general, general connection handle and a small amount of special tooling. The handle to join the cutting tool and machine tool power head in therefore has gradually standardization and seriation. There are different ways to the classification of nc tool. CNC machining cutting tool monitoring tool largely determines the quality of the workpiece processing quality. WeChat public number: UG CNC programming, in the process of automatic processing cutting, through sound monitoring control, cutting, cutting time suspended in the process of inspection, the workpiece surface analysis methods such as judging tool normal wear condition and the status of the non-normal damage. According to the machining requirements of cutting tool processing in time, prevent produced by cutting tool is not handled in time and processing quality problem.
