This 2 jaw lathe chuck can simultaneously clamp the workpiece radially and axially pull it back, keeping the workpiece tightly against the reference surface without lifting.
The 2 jaw lathe chuck can be combined with leak testing for axial position verification, making it ideal for machining requiring precise length.
The 2 jaw lathe chuck userd cylindrical sliding structure ensures high clamping precision and durability, suitable for heavy cutting applications.

The main advantages of using a 2 jaw lathe chuck include increased versatility and ease of use when handling specific workpiece shapes. Since it has fewer jaws, it provides quicker setup times and can accommodate parts that are not perfectly cylindrical. Additionally, a 2 jaw chuck allows for a greater diameter capacity when working with larger components, making it an excellent choice for various machining tasks.
While a 2 jaw lathe chuck is versatile, it is not suitable for all types of turning jobs. It excels with irregular or non-symmetrical shapes but may not provide the stability needed for cylindrical pieces that require more uniform gripping. For standard machining tasks on cylindrical workpieces, a 3 jaw chuck or 4 jaw chuck is typically preferred due to its ability to grip evenly from multiple points. Therefore, it's essential to evaluate the specific job requirements before choosing a chuck type.
