According to the Measures for the Evaluation of Science and Technology-based Small and Medium-sized Enterprises (Guo Ke Fa Zheng  No. 115), the Circular of the Ministry of Science and Technology and the State Administration of Taxation on Matters Concerning the Evaluation of Science and Technology-based Small and Medium-sized Enterprises (Guo Ke Fa Huo  No. 11), and the Guidelines for Evaluation Services of Science and Technology-based Small and Medium-sized Enterprises (Guo Ke Huo Zi  No. 67), the province was decided to carry out the 2023 evaluation of national science and technology-based small and medium-sized enterprises. It is decided to carry out the evaluation of national science and technology-based small and medium-sized enterprises in the province (except Ningbo, the same hereinafter) in 2023. The relevant matters are hereby notified as follows.
Five-axis milling and boring machining center process characteristics are determined by the production of the power head, mainly for drilling, tapping, boring, chamfering, milling, grinding and other types of processing to meet the processing needs of most customers. The power head is highly applicable and can be easily adjusted for different sized tools of the same type according to the type of tool used. Power head spindle with high rotary accuracy, good rigidity, no mechanical wear and vibration absorption, etc., suitable for cast iron, steel, non-ferrous metal materials, high machining accuracy can be combined with the stroke of the slide table to control the movement process of the power head, to meet the workpiece of a variety of modeling process characteristics. The guide rail and bed of the hard rail are integrated casting parts, and then the guide rail is processed on that basis, and then processed through quenching, grinding and then processed into the guide rail.
The so-called dimensional accuracy mainly refers to the degree of conformity between the dimensions of the workpiece and the dimensional requirements of the drawings after the completion of machining parts, so, in order to improve the dimensional accuracy of the parts in the operation of CNC machine tools, it is necessary to pay attention to the operating techniques in the operation of CNC machine tools, the dimensional accuracy of the parts of the commonly used methods of controlling the dimensional accuracy of the parts, such as the accurate tool setting, the adjustment of the tool wear compensation and the modification of the dimensional control accuracy in the program. Control accuracy, so that the size of the workpiece produced to be accurate.
in the CNC lathe reboot before the need for the machine's circuit boards for artificial preheating, you can also choose to use the electric hair dryer to each circuit board heating for a few minutes, as long as a little bit of temperature can be.
