It is necessary to manually adjust the fixing angle of the circuit board to make the grinding more comprehensive. Manually adjusting the angle of the circuit board is cumbersome and affects the efficiency of circuit board grinding. In addition, the circuit board requires workers to take the circuit board and fix it on the lower side of the grinder, which wastes a lot of time, reduces the burr removal efficiency, and cannot keep up with the output.
