company news about Structural Analysis of CNC Lathe

HR CNC lathes are widely used in various fields. The use of HR CNC lathes can avoid problems such as insufficient structural rigidity, poor seismic resistance, and high frictional resistance of sliding surfaces. And it is very helpful for improving turning efficiency and reducing cost expenditures. The following editor will explain to you the structural analysis of CNC lathes:
1、 Spindle and spindle box: The rotation accuracy of the HR CNC lathe spindle has a significant impact on the accuracy of the processed parts, and its power, rotation speed, and other factors also have a certain impact on the processing efficiency. If the spindle box has a level automatic speed regulation function, the transmission structure of the spindle box has been simplified. For the modified type with dual functions of manual operation and automatic control processing, the original spindle box is basically still being retained.
2、 Guide rail: The guide rail of HR CNC lathe provides guarantee for feed motion. To a large extent, it will have a certain impact on the stiffness, accuracy, and smoothness of the lathe during low-speed feeding, which is also one of the important factors affecting the quality of part processing. In addition to some using traditional sliding rails, HR CNC lathes that have been standardized for production have already adopted more plastic coated rails.
3、 Mechanical transmission mechanism: In addition to some gear transmission mechanisms in the spindle box, HR CNC lathe has made some simplifications on the basis of the original ordinary lathe transmission chain. The hanging wheel box, feed box, slide box, and most of their transmission mechanisms have been eliminated, while only the spiral transmission mechanisms for longitudinal and transverse feed have been retained. A gear pair has been added between the driving motor and the lead screw (some lathes have not added it) to eliminate its side clearance.
