Travelling column machining centers are ideal machines for machining medium to large-sized workpieces with large capacities. The main feature, in fact, that distinguishes them from the classic vertical machining centers... is represented by the fact that the work table is fixed, while to move along the axes x and y is the upright on which the head is housed with the milling tool. This particular technical characteristic essentially generates two great advantages in the machining of medium-large pieces. The first advantage relates to the load-bearing capacity of the table. As the table is fixed, it can support higher weights, which is essential for machining parts with heavy weights. The second advantage is a direct consequence of the first point. The table will not move along the x and y axes, as we have said this is fixed and supports the entire weight of the workpiece, but instead the upright on which the head is placed with the cutting tool will be moveable. Since the head does not have to bear the weight of the piece to be supported, it will be able to reach considerable positioning speeds that the classic vertical machining centres do not have at all. In the classic machining centers, in fact, the table that at the same time supports the workpiece is positioned along the x and y axes, with a consequent lower positioning capacity in a short time. The most advanced mobile column machining centers can also be equipped with 4 and 5 axes, making them real multifunctional machines. In the most complex configurations, the work area is composed of two different tables separated by a central bulkhead to allow working without downtime with loading and unloading operations carried out in masked time. This type of machining is called "pendular machining".
