Questions and solutions for jitter during grinding of crystal surface care machine

The standard method to check the jitter of the crystal plane machine is:

1. Take out the grinding disc and rotate it 120 degrees to snap it back to the gearbox chuck.

2. Install 6 pieces of 50# or 100# new water grinding discs on the aluminum grinding disc and grind on the flat stone ground.

3. You can see whether it is stable or not. If there is jitter, it means that there is a problem with the machine. If it does not jitter, it means that there is no problem!

4. The crystal surface care machine of any manufacturer does not have the problem of stable and unstable movement. The core part of the crystal surface machine is that the motor rotating shaft is closely connected with the gearbox. The whole is perpendicular to the base mounting surface. When the gearbox of the grinding disc rotates , its rotational runout error is within 0.01 to 0.02 mm, which is consistent with the level of the advanced machine tool turntable, so there is no such thing as an unstable movement.

5. If there is jitter, the possible reasons:

a. The fixing screws of the gearbox connecting plate are loose and tightened.

b. There is one or two places on the right side of the middle bayonet position of the aluminum grinding disc and the corners where the force is subjected to severe wear or uneven thickness. The small unevenness on the ground and the force transmitted to the gearbox chuck position when operating the machine handrail cannot be transmitted to the grinding disc at the same time. Because the force is mutual, the grinding disc is rebounded by the impact force of the small uneven ground to the gearbox body < box body and machine. The head and the base are the same whole>, so the machine shakes evenly.

6. Solution:

1>. Make the thickness of the arrows of the aluminum grinding disc the same, and stick adhesive tape on the back of the card position to thicken it, so that the arrows can be stuck in the vacant position of the gearbox head, and keep it tight and without gaps.

2>. Make the right corner of the three arrows of the aluminum grinding disc fully contact with the apex of the upper right corner of the three clamps of the gearbox body and fit tightly.
