Structural features of vertical lathe

Vertical lathes can generally be divided into single column and double column. Small vertical lathes are generally made of single columns, and large vertical lathes are made of double columns. The main feature of the vertical lathe structure is that its main shaft is in a vertical position. The main features of the vertical lathe are: the workbench is in the horizontal plane, and the installation and adjustment of the workpiece is convenient. The worktable is supported by guide rails with good rigidity and stable cutting. There are several tool holders and can be quickly changed. The machining precision of the vertical lathe can reach IT9-IT8, and the surface roughness Ra can reach 3.2-1.6um. The main parameter of the vertical lathe is the maximum turning diameter D.

The car is mainly used for processing large and heavy workpieces with large diameter and short length and workpieces that are not easy to be clamped on horizontal lathes. When the swing diameter is satisfied, the workpieces that are too heavy are not easy to be clamped in the sleeping car. Due to their own weight, the machining accuracy is correct. Influential, the use of vertical vehicles can solve the above problems.

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.

Structural features:
