Vertical lathes are large-scale mechanical equipment used to machine large and heavy-duty workpieces with large radial dimensions and relatively small axial dimensions and complex shapes. Such as various discs, wheels and sleeves of the cylindrical surface, end face, conical surface, cylindrical hole, conical hole and so on. It can also be machined, spheroidal, contoured, milled and ground with additional equipment. Compared with the horizontal lathe, the workpiece is clamped on the inside of the clip decoration of the horizontal lathe. The axis of the vertical lathe spindle is vertical, and the table top is in a horizontal plane, so the clamping and alignment of the workpiece is convenient. This arrangement reduces the load on the spindle and bearings, so the vertical lathe can maintain working accuracy for a longer period of time.
Vertical lathe for machining workpieces with large diameters and weights, or difficult to install on horizontal lathes, the main axis of the spindle is perpendicular to the horizontal plane, the workpiece is mounted on the horizontal rotary table, and the main motion of the table is rotated by the action. The feed motion is realized by the vertical tool holder and the side tool holder.
