Lathes: horizontal lathes and vertical lathes
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 worktable is in the horizontal plane, the installation and adjustment of the workpiece is more convenient. The worktable is supported by the guide rail, the rigidity is good, and the cutting is stable. One tool holder, and can quickly change the tool, the machining accuracy 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.
Horizontal lathe, with lathe bed, bed legs, oil pan, etc., adopts an integral casting structure, the headstock adopts a three-support structure, the feed box is provided with a metric thread conversion mechanism, and the slide box is provided with a tapered clutch for safety Device, the lathe machine is equipped with a four-station automatic feed mechanical collision stop device in the longitudinal direction, the tailstock is equipped with a speed change device, and the design of the lathe lubrication system is reasonable and reliable.
the difference:
1. The position of the main shaft is different. The main shaft of the horizontal lathe is on the left side of the machine tool, and the flat bed is used for axle and disc parts. The lathe has greater rigidity and is easy to exclude chips. The vertical main shaft of the lathe is perpendicular to the horizontal plane. A circular table with a large diameter is used to clamp the workpiece. It is mainly used to process large and complex parts with large radial dimensions and relatively small axial dimensions.
2. The structure is different, and the range of parts used for turning is different. The vertical lathe mainly processes large workpieces and workpieces that are not easy to clamp in the horizontal lathe. When the rotation diameter is satisfied, too heavy workpieces are not easy to clamp in the horizontal lathe. Processing accuracy has an impact, and the use of vertical lathes can solve the above problems.
