What kind of workpieces are suitable for processing on vertical lathe machines?

About CNC vertical lathe

A CNC vertical lathe is a CNC lathe with a spindle axis perpendicular to the horizontal plane, a worktable that rotates the workpiece in the horizontal plane, and a tool holder that feeds vertically or obliquely.

1.Processing advantages of vertical lathes

Vertical lathes are mainly used to process medium-sized, large, and heavy workpieces with large diameters and short lengths, and workpieces that are difficult to clamp on horizontal lathes. Compared with horizontal lathes, the clamping and alignment of workpieces are more convenient. The vertical lathe layout reduces the load on the spindle and bearings, and can maintain a high working accuracy. CNC vertical lathes can form a single-machine/multi-machine automatic line with the characteristics of high processing efficiency, high processing accuracy, and high degree of automation.

2.Main parts suitable for processing

Due to its structural characteristics and processing capabilities, CNC vertical lathes are suitable for processing a variety of parts such as discs, short shafts, and sleeves, and are suitable for processing flywheel discs, flanges, brake discs, pulleys, brake drums, bearing rings, main bearing caps, cylinder blocks, transmission cases, molds, etc. Suitable for processing special-purpose parts, such as engine parts, wheel hubs, turbine blades, wheel rims, shock absorber seats, etc. It is widely used in the automotive, aerospace, rail transportation, engineering machinery, electric power, energy, general machinery and other industries.

As a large-scale production equipment, the main function of the vertical lathe is to process complex workpieces with relatively small axial dimensions but large radial dimensions, such as cylindrical surfaces, end faces, conical surfaces, cylindrical holes and conical holes of discs, wheels and sleeves. These processing capabilities make the vertical lathe particularly suitable for processing large and heavy workpieces.

Unlike the workpiece clamping method of the horizontal lathe, the spindle axis of the vertical lathe is arranged vertically, while the worktable surface is in a horizontal plane. This design makes the installation and positioning of the workpiece easier. The advantage of this layout is that it reduces the load on the spindle and bearings, thereby ensuring that the vertical lathe can maintain a high working accuracy for a long time, which is very important for precision machining. In addition, the vertical lathe is also equipped with additional devices, which can perform a variety of complex processes such as thread turning, spherical processing, profiling, milling and grinding, increasing its versatility and flexibility.

3.Vertical lathe technical specifications

In terms of technical specifications, vertical lathes have many features, such as hydraulic speed change in the main gearbox, electro-hydraulic operation to achieve the worktable speed, pressure-maintaining device in the vertical tool rest, spring clamping and hydraulic release in the crossbeam clamping mechanism, etc. These features together ensure the efficient operation of the vertical lathe and the precise processing of the workpiece. In addition, the feed mechanism of the vertical lathe is also equipped with a safety device to ensure the safety of operation. ‌

4.Application fields of vertical lathes

Vertical lathes have a wide range of applications, especially in the processing of large and heavy workpieces with large radial dimensions and relatively small axial dimensions. In addition, the application of vertical lathes in mining machinery and oil extraction equipment also shows its ability to efficiently and accurately process large and heavy workpieces. The structural design of the vertical lathe not only makes the installation and adjustment of the workpiece convenient, but also provides good rigidity and a stable cutting plane, thus playing an indispensable role in the field of mechanical processing.
