There are many different models of vertical machining center, in the selection, it is necessary to consider many factors, so as to choose the appropriate model of product, the main factors that need to be considered in the selection of vertical machining center are:
1. Size of machining center
Different sizes of machining centers are suitable for processing parts are different, the floor area is also different, the general large-size machining centers such as gantry machining centers, mainly used for the processing needs of large-size complex parts; Ordinary vertical machining centers process normal workpieces.
2. Machining center accuracy
The accuracy of the CNC machining center is subject to relevant standards, and the factory accuracy of the general vertical machining center has a considerable reserve, which is about 20% compressed by about 20% compared with the tolerance value of the national standard. Therefore, from the perspective of precision selection, the general CNC machining center can meet the processing needs of most parts. For parts with high precision requirements, precision CNC machining centers should be considered.
3. The processing volume of the workpiece of the machining center
The model selection of vertical machining center should also consider the size of the processing volume, and the vertical machining center suitable for large and medium batch processing needs is different.
4. CNC system of machining center
For the machining part is a frame-shaped plane or unequal height of the steps at all levels, then the CNC machining center of the point linear system can be selected. If the machining part is a surface profile, the two-coordinate linkage and three-coordinate linkage system should be selected according to the geometry of the surface. According to the requirements of parts processing, on the basis of the general CNC machining center, the CNC indexing head or CNC rotary table can be added
