How to correct the three-jaw chuck in hydraulic chuck?

Hydraulic chuck Three-jaw chuck will suffer from reduced coaxiality, unstable accuracy and bell mouth phenomenon after being used for a long time, which directly affects the processing accuracy and clamping reliability. Practical experience has proven that the following method of correction is high-efficiency, fast, simple to use, and has obvious effects.

Taking the positive jaw chuck as an example, first use an external clamp to clamp a round bar of appropriate diameter, start the machine tool, and turn the outer circular part of the jaw. Then use an inner support to clamp a ring-shaped piece, start the machine tool, and turn the inner circular part and end face of the claw. Obviously, this can significantly improve the coaxiality between the machined inner circle of the claw and the machine tool spindle and eliminate the bell mouth phenomenon, thereby achieving higher accuracy and achieving the purpose of correction.

The principle of the hydraulic chuck is to use a hydraulic cylinder to push the chuck to clamp and loosen, and the middle is connected through a tie rod (a steel pipe with threads at both ends.)

The main accessories include hydraulic chuck, hollow cylinder, tie rod, cylinder holder, chuck connecting plate, and hydraulic station set. You can use a foot switch or purchase an electric control box to control the electromagnetic signal.

During the modification process, it is necessary to correct the parallelism and accuracy of the chuck and the spindle. As for the installation details, they are generally introduced in the product manual of the chuck and cylinder. You can refer to the manual for installation and modification.
