CNC lathe chuck types
CNC lathe is a type of high-precision, high-efficiency automated machining equipment. There are various types of chucks used on its spindle, which can be categorized based on their clamping methods and structural characteristics. The following are types of chucks commonly used on CNC lathes:
1. Three-jaw chuck:
The three-jaw chuck is one of the most common types, often used for clamping circular workpieces. It achieves clamping and releasing of workpieces by evenly distributing three jaws around the circumference. Its advantages include uniform clamping force and easy operation, suitable for most lathe machining tasks.

2. Two/Four-jaw chuck:
The two-jaw chuck is characterized by strong clamping force, wide clamping range, higher strength and wear resistance. Meanwhile, its clamping force is stable and reliable, and it has a unique sealing structure and high-quality seals, which makes the chuck's sealing performance better.
The four-jaw chuck is suitable for clamping non-circular workpieces, such as square or hexagonal shapes. Compared to the three-jaw chuck, the four-jaw chuck provides more stable clamping force, ensuring the machining accuracy and stability of workpieces.
