Round cutting platform

The utility model discloses a circular cutting platform which comprises a circular platform body, a square adsorption area is arranged on the surface of the circular platform body, an adsorption opening is formed in the center in the adsorption area, and a plurality of inwards-concave annular adsorption grooves are evenly formed in the adsorption area from the center of the adsorption area to the outside. Inwards-concave linear adsorption grooves are formed in the adsorption area in the diagonal direction, the multiple annular adsorption grooves are communicated with the center adsorption opening, an adsorption channel communicated with vacuum adsorption equipment is formed in the center of the back face of the surface of the circular platform, and the adsorption channel is communicated with the adsorption opening. The circular stainless steel platform is adopted, the vacuum adsorption function in the adsorption area is achieved through the arrangement of the linear adsorption groove, the annular adsorption g
