Wrench-operated lathe chucks are among the most commonly used types of chucks in turning machines, known for their simple design and precise mechanical performance, making them widely popular in industrial workshops. In this type of chuck, the jaws are adjusted by turning a dedicated wrench, which opens or closes all jaws simultaneously. This mechanism is designed so that the jaws move concentrically with respect to the machine axis, allowing for accurate and stable clamping of the workpiece. The body of a wrench-operated chuck is typically made from hardened steel to withstand wear, repeated pressure, and mechanical impacts. These chucks are ideal for applications where high precision is required and frequent workpiece changes are not necessary.

Structurally, a wrench-operated chuck consists of three accurately machined jaws connected to a central scroll gear system that is engaged by the chuck key. As the wrench rotates, it transmits torque to the scroll plate, causing the jaws to move inward or outward in unison. One of the technical advantages of this chuck type is its ease of maintenance and high reliability under workshop conditions. Additionally, the jaws are designed to be compatible with various cylindrical and hexagonal workpieces. When purchasing a wrench-operated l

Three wrench systems

The wrench-type lathe chuck is one of the most commonly used chucks in turning machines, known for its simple design and manual mechanism that allows precise control over clamping the workpiece. The main body of this chuck is typically made from high-strength alloy steel and undergoes hardening treatment to enhance durability. The jaws of a wrench-type chuck are operated manually using a dedicated chuck key, enabling accurate positioning of the workpiece. This type usually features three synchronized jaws that move simultaneously to center the workpiece along the axis of rotation — a critical feature for maintaining balance and improving machining accuracy.

Structurally, the wrench-type chuck includes a spiral or gear-based force transmission system that distributes the clamping force evenly to the jaws as the key is turned. This ensures that the jaws grip the workpiece with uniform pressure, minimizing slippage or play during operation. These chucks are manufactured in a variety of sizes and diameters to suit different manual and industrial lathe machines. Choosing the right chuck depends on factors such as clamping capacity, jaw dimensions, body material, and spindle compatibility. Due to their affordable price, high durability, and ease of maintenance, wrench-type chuck
