Understand the working principle of the thinning machine


What is the principle of the thinning machine? The thinning machine is controlled by a stepless speed regulation system, which can easily adjust the suitable thinning speed of various parts. Electric-gas proportional valve closed loop feedback. Pressure control, can independently regulate the pressure equipment. The upper disc is provided with a slow-down function, which is useful to prevent the breakage of thin and brittle workpieces.

 

Through a time relay and a thinning counter, the thinning time and the number of thinning turns can be accurately set and controlled according to the processing requirements. The pressure mode can be adjusted during operation, and when the thinning setting time or lap speed is reached, it will actively stop and give an alarm to complete semi-active operation.

Thinning machine speed control method, thinning processing has three stages, namely, the beginning stage, the formal stage and the end stage, the beginning stage of the grinding tool speed rotation, the formal stage of the grinding tool constant speed rotation, the end of the grinding tool speed rotation, which is characterized by the beginning of the thinning processing stage.

The acceleration of the rotating speed of the abrasive tool is artificially controlled to increase from zero from slow to fast. When the rotating speed of the abrasive tool rises to half of the official thinning speed, the change of the acceleration presents an inflection point. The acceleration of the rotating speed of the abrasive tool is controlled to decrease from fast to slow from the maximum value until the rotating speed of the abrasive tool reaches the official thinning speed and the acceleration of the rotating speed of the abrasive tool drops to zero.
