The vertical CNC lathe is a high-efficiency CNC equipment widely used in the processing industry. Its structure includes the following parts.

1. Spindle and spindle box:
The spindle is one of the core components of the vertical CNC lathe. Its function is to connect the main machine tool system and drive it to rotate. Generally, the spindle is made of high-strength alloy steel and steel materials, which can withstand high speed and large load, and can achieve high-precision processing during use. The spindle box is the frame of the spindle, which is equipped with many key components (such as bearings, gears, etc.) to support and drive the spindle.
2.Chuck and automatic jamming:
The chuck is a common fixture for clamping workpieces in vertical CNC lathes. Its main function is to fix the workpiece on the spindle and realize processing by rotating it. A chuck usually consists of a skeleton, a claw, a chuck piece and other components. The automatic jam is a device that can realize automatic material changing and positioning. It has the advantages of high precision, high efficiency, high stability, and high automation characteristics.
3. Guide rails and sliders:
Guide rails and slides form the basic structure of a vertical CNC lathe. Their main function is to support and position the workpiece to maintain high precision during rotation and cutting motion on the spindle. Guide rails are divided into bed guide rails and beam guide rails, which are usually made of Hastelloy cast iron materials. The slider realizes processing by sliding on the guide rail. It is usually made of moderately sized materials with a strong steel structure that can withstand the sudden machining forces.
4. Tool holder and composite tool holder:
The tool holder is used to load cutting tools of different types and uses. It can ensure the accuracy of the movement trajectory of the machine tool during processing, as well as the matching clearance between various parts of the machine tool. The composite tool holder is a cutting tool that can realize multi-functional tool change. It can realize cutting operations in a variety of different directions and has higher production efficiency and flexibility.
To sum up, the structure of a vertical CNC lathe mainly includes the spindle and spindle box, chuck and automatic chuck, guide rail and slide block, tool holder and composite tool holder. These components work together organically to achieve efficient, high-precision automated processing.
