Horizontal machining center refers to a machining center with the spindle axis parallel to the worktable. It can be used for: box parts. The basis of its operation is that the computer can automatically select different tools after the workpiece is clamped on the machining center once , Automatically change the spindle speed of the machine tool, and complete the working process of multiple faces on the workpiece in sequence. Horizontal machining centers will play a huge role in actual use. What problems should we pay attention to when we use them? If there is a problem with the cooling system of the horizontal machining center, it will cause the spindle motor to overheat, which will accelerate the wear of the bearing and cause the physical damage of the spindle motor. Therefore, be sure to check whether the cooling system is in normal working condition before use. There is no guarantee for the quality of the spindle motor itself, and the spindle motor produced by a small manufacturer may be damaged at any time. Therefore, a big brand must be selected when the spindle motor of the horizontal machining center is used. In the use of machinery, the operating system version is too low or the use system is not perfect, which causes the horizontal machining center to start working without reaching the required speed, which will increase the engraving resistance and damage the engraving machine. If the horizontal machining center is not properly protected against freezing, it will cause damage to the spindle of the engraving machine of the machining center. When using the horizontal machining center, we must master the relevant maintenance methods, so as to make our work smoother.
