The horizontal machining center is one of the most commonly used CNC machine tools

The horizontal machining center is one of the most commonly used CNC machine tools, and its high technical content is one of the iconic products of the development level of the CNC machine tool industry. The horizontal machining center mainly controls the basic movement of the machine tool through the numerical control system and the servo drive device. The main feature of the structure is the horizontal setting of the spindle. It is usually composed of 3-5 moving parts (headstock, table, column or spindle sleeve, etc.). An automatic exchange table is arranged on the horizontal machining center to form a flexible manufacturing unit (FMC), which realizes automatic exchange of workpieces, that is, another workpiece can be loaded and unloaded while being processed. After the workpiece is clamped once, the multi-process automatic machining is completed, the tool is automatically selected and replaced, the spindle speed and feed speed of the machine tool are automatically changed, the movement track of the tool and the workpiece is automatically realized, and other auxiliary functions are automatically realized.

The horizontal machining center is suitable for mass production of products with complex shapes and high precision requirements, especially for the processing of boxes and complex structural parts. It is used in the automotive, aerospace, marine and power generation industries for sophisticated and efficient machining of complex parts. The level of domestic horizontal machining centers has been greatly improved, and it can reach the high-speed and precision machining of general parts, which can basically meet the needs of users, but compared with the international advanced level, in terms of accuracy, efficiency, intelligence and reliability. There are still gaps, so the import volume of high-end horizontal machining centers is large.
