Structure and working principle

This model mainly consists of a vibration motor, a container with sorting, a support spring, and a base. The vibration motor is fixedly connected to the container with bolts and sits together on the spring connected to the base.

During the grinding process, the container is the main vibrating component and should have good rigidity, so it is welded with steel plates. In order to avoid scratches during vibration and reduce noise, rubber or polyurethane lining is applied to the inner wall of the container,

Rubber materials have wear-resistant, acid resistant, and alkali resistant properties, and can withstand oil when used alone. Polyurethane materials have higher wear resistance.

The upper and lower parts of the vibration motor have two unbalanced loads. By adjusting their relative positions, the horizontal and vertical amplitudes can be adjusted to meet the different finishing needs of various types of parts.

When the vibration motor shaft rotates at high speed, the unbalanced load generates centrifugal force and tilting moment, and the container produces regular vibration through the action of the spring. Due to the circular shape of the bottom of the container, the forces and amplitudes at each point are different,

The grinding stone and workpiece in the container revolve around the center cylinder of the container and roll around the center of the circular ring, and their combined motion is a circular spiral motion. Because the abrasive and workpiece produce relative motion during motion, the grinding stone can perform finishing on the workpiece.

The grinding process of a spiral vibration grinder is a type of vibration grinding process. The workpiece that needs to be deburred and polished is placed in a pre prepared container of grinding agent with grinding stones, and relies on the regular vibration of the container,

Generate relative motion between the workpiece and the grinding stone, grind them together, remove burrs protruding from the surface and periphery of the workpiece, and round the sharp edges and polish the surface.

The basic structure and workpiece principle of a flat bottomed vibration grinder are the same as those of a spiral vibration grinder.
