The hydraulic chuck trimming method is introduced as follows. If you are a group engaged in this industry, you can always find out.

① Clearly correcting the claw principle, simply speaking, the machine tool is equipped with a chuck, so that the chuck is clamped after clamping the bar or the trimmer (removing the gap between the main jaw and the chuck), repairing the clamping workpiece a circular arc surface that is concentric with the spindle

② Hydraulic chuck common problems:

1). Do not empty repair. There is a gap between the main jaw and the chuck body when the chuck is not clamping the workpiece. When the chuck is empty, the knife turns the soft claw, and the soft claw drives the main claw to shake together to make it repair. The arc is irregular and has a small amount of deviation.

2). The claw-cutting method, the claws hold a fine car round bar or buy a chuck trimmer.

③ Set the machine parameters.

④ Pay attention to roughness, chamfering, clearing roots, removing burrs.

⑤ Hydraulic chuck to check the axial and radial runout.

⑥ Clamp the workpiece, repeat the clamping, check the accuracy, and complete the claw repair. The teeth of the lands are straightened according to the measured values of the actual spindle.
