According to the main shaft, CNC milling machines can be divided into three types: vertical CNC milling machines, horizontal CNC milling machines, and vertical and horizontal CNC milling machines.

According to the number of control axes, it can be divided into 2.5-axis CNC milling machine, 3-axis CNC milling machine, 4-axis CNC milling machine, and 5-axis CNC milling machine.

What are the categories of CNC milling machines according to the spindle?

Vertical CNC Milling Machine

The axis of the spindle of the vertical CNC milling machine is perpendicular to the horizontal plane, and the axis of the spindle of the CNC milling machine is perpendicular to the horizontal plane. Judging from the number of coordinates controlled by the CNC system of the machine tool, 2-coordinate CNC vertical milling still accounts for the majority; generally, 3-coordinate linkage processing can be performed, but some machine tools can only perform any two-coordinate linkage processing among the 3 coordinates (usually Called 2.5 coordinate processing). In addition, there are 4-coordinate and 5-coordinate CNC vertical milling in which the machine tool spindle can perform CNC swing angle movement around one or two of the X, Y, and Z axes.

Gantry CNC milling machine

The spindle of the CNC gantry milling machine can move on the horizontal and vertical guide rails of the gantry frame, and the gantry frame moves longitudinally along the bed. Large-scale CNC milling machines often use a gantry mobile type to consider technical problems such as expanding the stroke and reducing the floor space.

Horizontal CNC Milling Machine

The horizontal CNC milling machine is the same as the ordinary horizontal milling machine, its spindle axis is parallel to the horizontal plane, and it is mainly used for processing box parts. In order to expand the processing range and expand functions, horizontal CNC milling machines usually use CNC turntables or universal CNC turntables to achieve 4 and 5 coordinate processing. In this way, not only the continuous revolving contour on the side of the workpiece can be machined, but also "four-sided machining" can be realized by changing the station through the turntable in one installation.

Vertical and horizontal CNC milling machine

The spindle direction of the vertical and horizontal CNC milling machine can be changed, so that both vertical and horizontal machining can be performed on one machine tool, and it has the functions of the above two types of machine tools. It has more room for selecting processing objects, which brings a lot of convenience to users.

The vertical and horizontal CNC milling machine can change the spindle direction manually or automatically. Some vertical and horizontal CNC milling machines use a universal CNC spindle head whose spindle head can be converted in any direction, so that it can process workpiece surfaces with different angles from the horizontal plane. "Five-sided machining" of parts.
