Horizontal machining centers can be divided into 3-axis, 4-axis, and 5-axis vertical machining centers based on the number of feed axes.
If the turning function is assigned to the table of a 5-axis machining center, it is classified as a 5-axis millturn horizontal machining center.
The 3-axis horizontal machining centers are mostly composed of three axes (X, Y, Z).
The 4-axis horizontal machining centers consist of three linear movement axes (X, Y, Z) and one rotational movement axis (one of A, B, C). The characteristics of the machine can vary greatly depending on the position of the rotational axis.
The 5-axis horizontal machining center consists of three linear axes (X, Y, Z) and two rotational axes (two of A, B, C). The characteristics of the machine can vary greatly depending on the position of the rotational axes.
The 5-axis millturn horizontal machining centers consist of three linear axes (X, Y, Z) and two rotational axes (two of A, B, and C). Its table is equipped with a turning function.
3 Machine structure3-1. Bed type
Bed type refers to the boring machine with a table on the bed, the table forms the X or Z axis. The bed types are further divided into table type, planer type, and reversed-T type.
The bed is equipped with a saddle to form the Z-axis, and the saddle is equipped with a table to form the X-axis. The column is fixed, and the milling spindle head is mounted on the column to form the Y-axis and moves up and down.
The bed is directly equipped with a table to form the X-axis, and the column is mounted on the bed to form the Z-axis. The milling spindle head is mounted on the column to form the Y-axis and moves up and down.
T-shape HMC is similar to planer type horizontal boring machine in structure.
Also known as a T-shaped horizontal machining center.
The bed is directly equipped with a table to form the Z-axis, and the column is mounted on the bed to form the X-axis. The milling spindle head is mounted on the column to form the Y-axis and moves up and down.

Three linear axes are located on the column in a column type horizontal machining center.
3-3-1. Fixed-head Moving-column type(Base-Z Column-X)
On the bed, the column base forms the Z-axis, and on the column base, the column forms the X-axis.

Tables of horizontal machining centers are mostly a square or rectangular shape.
The rotary table of 5 axis millturn horizontal machining centers often have circular shape.
Some rotary tables of 5 axis millturn horizontal machining centers have circular shapes with parallel edges.
In 5-axis horizontal machining centers, a rotary table can be mounted into a fixed rectangular table. In this case, the surfaces of the two table surfaces are on the same plane.
The rotary type is a method of exchanging pallets by setting a rotating mechanism between two pallets.
