Vertical Lathe, also known as floor turning machines, pillar turning machines, manual single-column turning machines, suitable for machining rolling pieces with a large diameter and length, cylindrical, circular cone, and non-circular surface contours with a complex rotary part, as well as internal and external threads. Mainly used for rough and fine turning of disc, ring, flat and rotating parts on steel structure, bearing, automobile, petrochemical and military industries.
1.Main structure
The vertical lathe is mainly composed of the bed, worktable, headstock and tailstock, main motor and mechanism. The bed is the foundation of the whole machine tool. It is made of cast iron and is a frame. It is mainly used for the installation of parts such as column and base. The workbench is a rotating part for the workpiece to be machined, which is composed of a rotating turntable, turntable bearing, increase or decrease speed device, etc. The headstock and tailstock are mainly used to support the workpiece. It mainly consists of a clamping device, a feed box and an indicator. The main machine of the vertical lathe is used to provide driving power. It is usually driven by DC or frequency conversion motor. The mechanism is used to achieve the improved function of the vertical lathe, such as working speed change, automatic feed, etc.
2.Working principle
The working principle of the vertical lathe is mainly the rolling of the roller on the inner surface of the turret to drive the disk to drive the table. The turntable wheel is arranged for every 12° through the turntable wheel drive shaft, which can drive the main motor through the transmission mechanism, thereby driving the turntable. When feeding, the feed wheel in the feed box drives the nut and then drives the inner hole sleeve of the headstock so that the sleeve can be fed for processing. In order to realize the relationship between the workpiece and the tool, the spindle motor adjusts the tool to the appropriate position and angle. During the processing, the spindle motor is constantly adjusted to achieve the machining effect.

4.Advantages
The advantages of the vertical lathe include: (1) The cutting tool has a good cutting line and a long service life, and the surface of the workpiece is high in accuracy. (2) The two sides of the workpiece can be machined simultaneously without manual intervention to reduce labor intensity. (3) The cutting parameters are clear and can be adjusted according to the requirements of the processing accuracy. (4) The system program is simple and easy to operate, and the safety devices are complete and reliable to ensure the safety of operation.
5.Applications
Due to its high machining accuracy, stable quality and high work efficiency, the vertical lathe is widely used in a variety of fields. It is mainly used for turning large parts such as disc, inner and outer circle, cylinder, cone, non-circular surface, internal and external threads, etc. It can be used in the production of steel structures, bearings, automobiles, military industry, etc. In addition, it can be used in the production of large parts such as printing rolls, large transmission parts, and turbines.
