According to the main processing center often in space where the state is divided into vertical machining center and horizontal machining center spindle machining center in space in a vertical state called vertical machining center spindle in the space in the state level is called horizontal machining center. Spindle can be used for vertical and horizontal conversion, known as vertical horizontal machining center or five face machining center, also known as composite machining center. According to the number of machining center column; a single column and double column (Longmen).

According to the processing center coordinates and the number of coordinates of the control points: three axis two linkage, the three axis of the three linkage, the four axis of the three linkage, the five axis of the four linkage, the six axis linkage, etc.. The three axis, the four axis refers to the machining center with the number of coordinates, linkage refers to the control system can control the coordinates of the movement, so as to achieve the relative position of the workpiece and speed control.

According to the number and function of the table: a single bench processing center, double bench processing center, and multi bench processing center.

According to the processing accuracy: there are ordinary machining centers and high-precision machining centers. Ordinary machining center, the resolution of 1 m, the maximum feed rate of 15~25m/min, positioning accuracy of l0 M. High precision machining center, the resolution is 0.1 M, the maximum feed rate is 15~100m/min, the positioning accuracy is about 2 m. Between 2~l0 m, to 5 m more, can be called precision level.
