CNC centering machine processing belongs to the precision processing equipment, can be completed at the same time vehicles ﹑ milling, drilling ﹑ boring ﹑ composite processing, such as attack, engraving, etc., mainly used for batch processing of precision hardware, shaft shaped non-standard parts. Compared with the machining center, it has a qualitative leap in processing efficiency and accuracy, because the choice of two-axis arrangement of tools greatly reduces the processing cycle time. According to reduce the tool exchange time between the row of tools and the opposite tool platform, various tool platform overlap function, thread cutting effective axis movement overlap function, secondary processing direct spindle indexing function, shorten the empty walk time.
In order to improve the CNC machining plant of high precision, high reliability of the application of new functional components has become inevitable. Representative new functional components include.
1, high-frequency electric spindle: high-frequency electric spindle is the integration of high-frequency motor and spindle components, small volume. High speed. Stepless speed control and a series of advantages have been widely used in a variety of machine tools.
2, linear motor: In recent years, the application of linear motor is becoming more and more common. Although their price is higher than the traditional servo system, but they are subject to interference with load switching. Compensation for thermal expansion . The use of core technologies such as magnetic isolation and protection simplifies the mechanical transmission structure and improves the dynamic performance of the machine tool.
3, electric ball screw: electric ball screw is the integration of servo motor and ball screw, which can greatly simplify its structure, the transmission stage is less. A series of advantages such as compact structure.
