Qianxinan surveying and marking mechanism manufacturer the like series CMM and measuring scribing machine manufactured by Beijing lice Xinxing Digital Technology Co., Ltd. are the company's leading products. The product is widely used in automobile, motorcycle, engineering machinery, aerospace, mold and industrial manufacturing industry, and has been well received by users. That is to say, only when the human body touch can the normal start-up, the requirements of use have been relatively improved. When the fingers touch on the metal layer, the touch screen can calculate the good touch point through the program to help the user to use normally. This kind of touch mode is more accurate and safe, and can be applied in some industries with high precision requirements, which helps to improve the efficiency of equipment detection. The like series of lit CMM scribing machine produced by Beijing lice is an economical product specially developed for scribing. At the same time, it has the advantages of good openness, flexible operation and light overall weight. It can meet the needs of scribing, and has a large number of users in various industries. ? the mechanical part has simple structure and good economic performance;? The main machine material is all steel or aviation aluminum structure;? The electronic control system can be configured with like series control system or various mainstream imported electronic control systems;? The software is equipped with the measurement software developed by Beijing lice. The company has a number of offices in the country, built a rapid response team, engaged in product sales, technical services, technical support and training, to provide quality services for the majority of users. measureTechnical features: high precision marking head can realize 0 ℃ and 90 ℃ double position, large swing, 360 ℃ rotary marking, especially suitable for surface, rough surface marking. The precision handwheel integrates quick action, locking and fine adjustment, with unlimited fine adjustment travel, convenient operation and time saving. All steel structure, the whole system (mechanical body, position sensor - magnetic grating ruler, measured workpiece - mostly steel parts) has one to one thermal expansion coefficient, stable system and good environmental adaptability. The high precision, high reliability three-dimensional probe is fully compatible with Renishaw probe, and the measuring force is adjustable. It can support different types and weights of measuring points, and its service life can reach more than 1 million times. The two computers can work on line or independently. Digital display meter four axis display. ? the equipment is easy to operate, easy to learn and use, and can be proficient in short-term training. The error detection methods of CMM can be divided Types Of Food Packaging Machines into two categories: one is to use laser interferometer and other instruments to detect individual original errors of CMM; the other is to use ball array, ball plate and other physical benchmarks to detect the comprehensive error of CMM, and then decompose the original error. It is possible to detect these errors with high accuracy by using laser interferometer directly. The disadvantages are that the laser interferometer is expensive, requires high environmental conditions and requires high technical level of the operator. Ball array, ball plate and other physical benchmarks need to be verified by laser interferometer,14 Heads Multihead Weigher which has higher requirements for the stability of the ball plate itself. When decomposing the original errors, an important basis is the good repeatability of CMM itself. By the comprehensive errorWhen decomposed into single error, it is inevitable to have cross effects. The uncertainty of the original error obtained by decomposition is larger than that measured directly by laser interferometer.
