High-grade numerical control machine tools used in the bus-cnc system, direct drive feature fully integrated system "to achieve a bus-type high-grade numerical control system , Bus-drivers, high-speed and high precision of the key features of the organic integration, formed a complete system of control. Integration System technology, products from foreign-independent R & D and manufacturing companies, with independent intellectual property rights, suitable for a variety of high-grade NC The application of machine tools, high-grade numerical control machine tools to improve the performance. Surface Grinder compared with lathes, milling machines, such as use of numerical control system rather late, because of its numerical control system to the specific requirements. Over the last decade, with CNC technology, Grinder Dressing in a row on the wheel, automatic compensation, automatic exchange wheel, multi-table, automatic transmission and fixture parts, and other operational functions to be achieved, numerical control technology on the surface grinder gradually universal. Recent large-scale machine tools exhibition, CNC grinding machine in the whole Grinder in the account for the majority of the exhibits, full-featured CNC-mill, has already become mainstream in the development of high-grade NC-mill at the same time, began to actively in the development of low-grade NC-mill. Molding plane and grinding machine cnc system, the control shaft extension request flexible to control up to nine coordinates, of which six coordinates can be linked, the smallest pulse equivalent, the mobile equivalent and testing are equivalent 0.1μ m, also a mill-linear position sensor [grating feet, Inductosyn] the entire closed-loop manner. Strengthen the fixed grinding method: According to grinding parts of different shapes, there are four different methods of grinding, with sand Axle tilt angle control function, Arakawa grinding, Cumo, Jingmo, no grinding sparks a set of grinding cycle, Dresser compensation, relative to the dressing-dressing round of the direction of the normal control functions, the outer edge of dressing wheel radius Compensation, the system resolution can be set to 0.1 μ m, a compact cnc system.

Microstructure is not as a basis for acceptance, but the cnc machine casting production enterprises, must be controlled as the most important item. Casting Machine because of the strength and the ability to maintain dimensional accuracy, rigidity, wear resistance and cutting performance has high demands, and the gray iron there must be a good performance of these organizations to ensure that the microstructure, and good microstructure, Through strict control to ensure that the process, such as strict management of the charge, a reasonable charge ratio, the best melting control, a serious inoculation and appropriate pouring temperature, one can not do. Microstructure out of control, show that the majority of China's machine tool enterprises in the casting process control is not strict, and it is very arbitrary. We visited some of the main cnc machine casting enterprises, most enterprises have metallographic inspection means, but it was not serious analysis of the examination results And analysis of the results reflected in the process control system. Some plants after a brief inspection in a written record of the conclusions, some in the form filled out a conclusion to the quality inspection departments, as the bureaucratic muddle through. We have to a plant, see a recent quality inspection report, simply write a "form of graphite type A" and out of the sample under a microscope to observe that the sample of A-type graphite only 43 per cent, while test Said: "As long as one of type A, we write A-type." This inspection is more terrible than useless, is actually self-comfort, self-deception. Some plants are simply cancel the microstructure of the test. Only serious test of individual plants microstructure, and maintain high-quality products. Not a corporate control of the elastic modulus of cast iron gray iron modulus of elasticity is the impact of cast iron rigidity and dimensional stability of the important performance indicators, speaking on cnc machine casting is particularly important. Impact of gray iron modulus of elasticity is the main factor in the form of graphite, and its length in iron levels in the percentage of the volume. Therefore, the strengthening of inoculation, control of the microstructure is to improve the elastic modulus of the key. Production abroad cnc machine castings, will be elastic modulus as a major-controlled items, because of its strict control of the process, better quality metallurgical, gray iron Modulus of the indicators is quite high.
