Three-dimensional overall layout design of CNC carving and milling machine tool

3 d CNC carving and milling machine is mainly used for small milling amount or soft and machining of metal materials. Requires not only the machining accuracy is higher, also to realize high speed cutting, the spindle speed and even up to 30000 r/min. The moving parts not only to good rigidity, and to be as light as possible, to ensure its flexibility. Requirements for numerical control system, it has high speed and excellent servo motor characteristics. For 3 d CNC carving and milling machine tool, from the Angle of the mechanical analysis of the structure should satisfy: rigid is better than moving parts, moving parts on the premise of guarantee the good rigidity, as light as possible, better flexibility. To meet the requirements of both light and rigid good from the machinery, the key is on the reasonable design of mechanical structure. 3 d CNC engraving and milling machine overall structure layout is shown in figure 1. Two-dimensional numerical control machine tool is mainly composed of cross table 5 ( X - Z to) , 1 (4 posts, one-dimensional nc workbench Y to) Pump, the spindle component 2, 3, operation and control cabinet 6 etc. Two-dimensional numerical control cross table and beam design as a whole, a dimension table and machine tool lathe bed base design. Figure 1 3 d CNC carving and milling machine tool overall arrangement of the gantry structure have good stiffness and symmetry, has long been the preferred structure of high speed cutting equipment. The machine's overall layout structure of gantry type milling machine, and designed a wide column and beam. To overcome the problem of bad moment, try to widen the X, Y, Z three to the span between two linear rolling guide, effective from the overall layout to ensure the rigidity of machine tool. For meehanite has good stability, the vibration absorption and resistance to impact, can make the bed had significantly improve the structural strength and rigidity, therefore the machine and lathe bed base use meehanite casting. It is box structure, internal steel plate by m type reinforced with mesh structure, ensure the workbench and two columns of Y axis bearing rigidity, the stability of machine tool dynamic processing can reach the best. For machine tool rigidity is mainly used to overcome the moving parts in high speed mobile strong shocks for the moving parts, so screw and guide rail should be some rough requirements, as far as possible when the design to strengthen rigidity. Thanks to these measures, yifan, CNC engraving machine co. , LTD. , the design of 3 d CNC carving and milling machine tool's biggest advantage is to compare small machining, the machining accuracy is higher, the soft metal for high speed cutting.
