Classification of CNC Milling Machines by Spindle Position

1. Vertical CNC milling machine

Vertical CNC milling machine spindle axis is perpendicular to the horizontal plane, is the CNC milling machine spindle axis is perpendicular to the horizontal plane, is a common form of layout in CNC milling machine, widely used.From the point of view of the number of coordinates controlled by CNC system of machine tools, 2-axis CNC end milling still accounts for the majority; In general, 3-coordinate linkage machining can be carried out, but some machine tools can only carry out any two of the 3-coordinate linkage machining (often referred to as 2.5 coordinate machining). In addition, there are 4-coordinate and 5-coordinate NC vertical milling where the machine spindle can rotate around one or two of the X, y and Z axes for NC swing angle motion.

2. CNC gantry milling machine

The spindle of CNC gantry milling machine can move on the horizontal and vertical guide rails of the gantry, while the gantry moves longitudinally along the bed. Large CNC milling machine, to take into account the expansion of travel, reduce the floor area and other technical problems, often using gantry mobile.

3. Horizontal CNC milling machine

Horizontal CNC milling machine is the same as ordinary horizontal milling machine, its spindle axis is parallel to the horizontal plane, mainly used for processing box parts. In order to expand the processing range and expand the function, the horizontal CNC milling machine usually uses the increase of CNC turntable or universal CNC turntable to realize 4,5 coordinate processing. In this way, not only the continuous rotary contour on the side of the workpiece can be machined, but also the four sides of the workpiece can be machined by changing the position through the turntable in one installation.

4. Vertical and horizontal CNC milling machine

The spindle direction of the vertical and horizontal CNC milling machine can be changed, which can achieve both vertical processing and horizontal processing on one machine tool. At the same time, it has the functions of the above two types of machine tools. It has a wider range of use, more complete functions, more room to choose processing objects, and brings a lot of convenience to users. The spindle direction of vertical and horizontal CNC milling machine can be changed manually or automatically. Some vertical and horizontal CNC milling machines use universal CNC spindle head, which can convert the spindle head in any direction, so that it can process the workpiece surface with different angles from the horizontal plane. In addition, a CNC turntable can be added on the worktable of this kind of milling machine to realize the five side machining of parts.
