The soft claw can ensure the repeated positioning accuracy of the workpiece to the greatest extent, so that the center line of the processed workpiece can completely coincide with the center line of the spindle, and the flat surface on the soft claw can also ensure the length of the workpiece.
The most important thing is that the soft jaws can fit the surface of the workpiece to the greatest extent, which can not only ensure the transmission of greater torque, but also avoid the clamping of the workpiece. These advantages are unmatched by the hard jaws.
Pay attention to the following issues when making soft claws:
1. The choice of soft claw material. "Soft" here means: good processing performance does not mean that it must be lower than the hardness of the workpiece.
For mass production, the hardness of the soft jaws will have a great influence on the stability of processing. Choosing a soft jaw material with higher hardness than the workpiece will not only increase the service life of the soft jaws, but also have a positive effect on the stability of processing. Impact.

2. Select the size of the soft jaws, the soft jaws must clamp at least 1/3 of the length of the workpiece.

3. For the installation position of the soft jaw on the chuck, it is not allowed for any T-block to exceed the maximum diameter of the chuck, which may pose a great safety risk.

4. The pressure and position when using the claw cutter.
It is recommended that the pressure during use is close to the pressure during processing of the workpiece. The chuck is in the middle of the range of motion during processing, and the direction of the clamping force during claw trimming is the same as the direction of the workpiece clamping force.
5. The influence of the diameter and speed of the chuck on the clamping force.
Due to the centrifugal force, the clamping force of the chuck will be greatly reduced when the chuck is operating at high speed. Please refer to the instructions on the chuck for details.
6. Make the inner hole the same size as the diameter of the workpiece to reduce the possibility of pinching the workpiece.
7. Add an undercut. To ensure repeated positioning of the workpiece.
8. Remove burrs and sharp corners on the soft claws. Be careful not to scratch your hands.
