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 case where I am a window, 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.

Ordinary horizontal lathe is a small ordinary machine tool with general lathe characteristics. It can turn inner and outer circles, conical surfaces, end faces, boring holes, cutting grooves, drilling holes, knurling, and can also be used for turning common metric and inch threads. Ordinary horizontal lathes are common lathes for organic seats. The lathe has the same structure, performance and use. It has the advantages of simple structure, convenient operation, large spindle diameter and small floor space. It is suitable for machines and instrument industries as small mechanical parts and repairs. Two types of English
