Polishing device for PCB production and processing

The utility model provides a polishing device for producing and processing a printed circuit board (PCB), which relates to the technical field of PCB production devices and comprises a polishing device body for polishing the circuit board and a clamping component for clamping the circuit board. The limiting pieces can limit and support the first support and the second support, the limiting supports at the tops of the first support and the second support clamp the PCB, and when the PCB deviates, the elastic pieces arranged between the first support and the limiting supports and between the second support and the limiting supports at the two ends are different in stress. When the PCB is clamped, the elastic pieces with large stress expand and extrude the limiting support at one end, so that the limiting support at the end drives the PCB to shift towards the middle, and the elastic pieces at the two ends extrude each other to clamp the PCB, so that the PCB is kept at the central position. 本实用新型提供一种PCB线路板生产加工用打磨装
