Principle and characteristics of self tightening drill chuck

March 23, 2023

Self tightening drill chuck is one of the accessory products of machine tools, mainly used to hold drilling tools and drill holes. It can be installed on lathes, milling machines, drilling machines, woodworking planers, electric hand drills, and impact drills. Self tightening drill chuck is a drill holding tool widely used in the fields of machinery manufacturing, construction and decoration.

The commonly used drill chucks mainly include wrench type drill chucks and self tightening drill chucks. "The components of wrench type drill chucks are mostly produced in large quantities using machine tools, resulting in lower prices. However, due to the limitations of its own structure, the accuracy of wrench type drill chucks is not high, and they are mainly used in desktop drilling machines,"

Small radial drilling machines, electric tools, and other occasions that require low clamping accuracy. In addition, the loading and unloading of drill bits requires a wrench to loosen and tighten, and the operation is complex. In machining centers, high-precision drilling machines, and other occasions that require high drilling accuracy, it is necessary to use self-tightening drill chucks when moving.

Principle and characteristics of self tightening drill chuck:

1. High precision, high clamping force;

2. With self tightening function, it is possible to lightly clamp the drill bit, synchronously increasing the clamping force as the torque increases during drilling, and producing

The high strength clamping force of Shengmingang prevents the drill bit from slipping;

3. Hardening treatment of vulnerable parts;

4. Taper holes can be used with various drill handles.

5. While bringing convenience to users, it can also bring profits to producers.
