High Quality CNC Lathe Three Jaw Self-Centering Manual Customized OEM Scroll Chuck

In order to maintain good accuracy of the lathe chuck after regular use, lubrication is important. Incorrect or inappropriate lubrication can lead to some problems, such as abnormal function at low pressure, weakened clamping force, poor clamping accuracy, abnormal wear, and seizure. Therefore, it is necessary to properly lubricate the chuck.

The utility model relates to an electric chuck device, which relates to a class of universal fixtures widely used in the mechanical field for clamping workpieces. It is composed of a clamping function unit of an electric chuck device, a power function unit of an electric chuck device, an electromagnetic friction clutch assembly, a chuck body shell, and an electromagnetic brake assembly. When the electromagnetic brake assembly is powered on, the electric chuck device clamping function unit is connected to the headstock as a whole and does not rotate; The electromagnetic friction clutch assembly is energized, and the power function unit of the electric chuck device transmits rotational motion to the gripper to clamp or release the workpiece. During processing, only the clamping function unit of the electric chuck device rotates with the spindle, while the power function unit of the electric chuck device does not rotate with the spindle. Compared with prior art, the present invention effectively reduces the number and quality of parts rotating with the spindle, is conducive to improving the dynamic balance quality of the spindle, is easy to serialize and standardize design and manufacturing, and has a simple and compact device structure, which is convenient for installation and maintenance.
