Basic knowledge of CNC machining center

Machining center is often divided into vertical machining center, horizontal machining center and gantry machining center according to the status of the spindle in the space. The spindle of the machining center is called vertical machining center in the space in a vertical state, and the spindle is called horizontal machining center in the space in a flat state.

Machining center (CNC and Computerized Numerical Control) is a highly automatic multi-function numerical control machine tool with tool house and automatic tool changing device.

Vertical machining center refers to the machining center with the spindle axis set vertically with the workbench. It is mainly used for machining plate, plate, mold and small shell complex parts. Vertical machining center can complete milling, boring, drilling, tapping and cutting threads and other processes. Vertical machining center is at least three axes two linkage, generally can achieve three axes three linkage. Some can be five axis, six axis control. Vertical machining center column height is limited, the box type of workpiece processing range to reduce, this is the disadvantage of vertical machining center. But the vertical machining center workpiece clamping, positioning convenient; The cutting tool movement track is easy to observe, debugging program inspection and measurement is convenient, can find problems in time, stop processing or modification; The cooling condition is easy to establish, and the cutting fluid can reach the tool and the machining surface directly. The three coordinate axes coincide with the Cartesian coordinate system, and the visual Angle is consistent with the pattern. The chips are easy to be eliminated and dropped, so as to avoid scratching the processed surface.

Horizontal machining center is an analytical instrument used in mechanical engineering, power and electrical engineering.

Horizontal machining center refers to the spindle for the horizontal state of the processing center, usually with automatic dividing rotary table, it generally has 3 ~ 5 motion coordinates, common is three linear motion coordinates plus a rotary motion coordinates, the workpiece in a card, in addition to the installation surface and the top surface of the remaining four surface processing, it is most suitable for plus box parts.

Longmen processing center refers to the axis of the main shaft Z axis and the vertical setting of the working table of the processing center, the overall structure is composed of double column and top beam of the large processing center frame of the portal structure, the middle of the double column and the beam. Especially suitable for processing large workpiece and complex shape workpiece.
