Description

Technical Field

[0001] The utility model relates to the technical field of tire grinding equipment, in particular to a special grinding tool for processing rice transplanter tires. Background Art

[0002] The flash that appears after the tire is produced may be caused by low mold precision, insufficient vulcanization time, uneven tire material, etc. Tire flash refers to the raised part between the two molds when the tire is molded, which not only affects the appearance of the tire, but also affects the performance and service life of the tire;

[0003] To deal with the flash on the outside of the tire, a professional trimmer or edge grinder is needed to flatten or grind off the flash on the outside of the tire.
