Part cutting and grinding device

The utility model belongs to the technical field of part machining, and particularly relates to a part cutting and polishing device which comprises a machining table, symmetrical supporting plates are fixedly arranged on the upper side wall of the machining table, a transverse plate is transversely and fixedly arranged at the upper ends of the adjacent sides of the two supporting plates, and a cutting mechanism is arranged at the lower end of the transverse plate. A scrap iron collecting opening is formed in the upper side wall of the machining table, symmetrical mounting plates are fixedly arranged at the upper end of the interior of the machining table, and a collecting groove is formed in the position, located at the lower end of the scrap iron collecting opening, between the two mounting plates. The two first electric push rods can drive the arc-shaped baffles to move upwards so as to block the front ends and the rear ends of the parts, chips generated during machining are prevented from splashing randoml
