Self-Centering Lathe Chuck 4'' for Lathe and 3D Printer

Introducing our 4'' 3-Jaw Self-Centering Lathe Chuck, constructed from high-strength HT300 material for exceptional compression resistance and durability. This lathe chuck is designed with both internal and external jaws, allowing for the secure clamping of larger industrial components without the need for constant recalibration.

Equipped with a self-centering function and bevel gear, our 3-jaw chuck ensures precise control over the accuracy of your workpiece during machining. With a bearing tolerance of ≤ 0.05 mm / 0.002", this lathe chuck guarantees structural stability and high precision.

Included with the lathe chuck are two types of jaws – internal and external – specifically designed for clamping larger industrial components. Using the provided T-shaped key, you can easily open and close the jaws for efficient operation.

The simple yet effective structure of this chuck, consisting of a chuck body, movable chuck, and jaw drive, allows for automatic centering when clamping a workpiece. Simply follow the correct installation order for smooth usage in woodworking, metalworking, drilling, or milling applications.

Crafted from superior HT300 material, our 3-jaw lathe chuck features a 20Cr steel chuck jaw with 53HRC hardness and a 40Cr steel scroll with 45HRC hardness. This ensures exceptional hardness and rust resistance for both small and large workpieces.

With a focus on high precision, the self-centering lathe chuck utilizes a meticulous machining process, including a bevel gear and three pinion gears, to achieve accurate machining progress. The clamping range of this chuck is 0.08-4 in/2-100 mm, making it suitable for a wide range of applications.

Experience simple and efficient operation with our 3-jaw lathe chuck, designed for ease of use and reliability. Suitable for various lathes, this chuck offers improved machining efficiency, operational flexibility, and consistent results for all your machining needs.
