AI Technical Summary
Traditional dual-head grinding machines suffer from asymmetrical force due to single-sided drive, resulting in severe wear of transmission components. The complex transmission mechanism increases the weight of the equipment, and the insufficient overlap of the grinding trajectory at low speeds affects the grinding quality.
It employs a combination of a self-rotation drive unit and a revolution drive unit, along with a gear shaft, a drive pulley, and a synchronous belt drive, and is equipped with an automatic tension adjustment mechanism for the synchronous belt to ensure independent power output of the grinding disc and stability of the transmission system.
This technology enables efficient and uniform grinding of the grinding disc, improves grinding quality, extends equipment lifespan, and reduces maintenance costs.
