[0021] The cooling mechanism 5 includes a cylinder 501 , a circular plate 1 502 , a circular plate 2 503 , an elbow 1 504 , an elbow 2 505 , a liquid inlet pipe 506 and a liquid outlet pipe 507 , and the channel mechanism 6 includes a semi-arc groove 601 , an annular groove 602 and a channel 603 .

[0022] See also Figure 2 There are two semi-arc grooves 601, which are respectively arranged on the front and rear sides of the center of the large circular knife body 1. The annular groove 602 is arranged on the outer circle of the large circular knife body 1. There are several channels 603, which are respectively connected with the semi-arc grooves 601 and the annular grooves 602. By setting the channels 603, the coolant entering into a semi-arc groove 601 flows into the annular groove 602, and then enters into another semi-arc groove 601 through other channels 603 for discharge.

[0023] See also Figure 1 and Figure 3 , circular plate 1 502 and circular plate 2 503 are rotatably embedded in the inner wall of cylinder 501 from right to left through sealed bearings respectively. By setting circular plate 1 502 and circular plate 2 503, the right end connecting area of ​​elbow 1 504 and elbow 2 505 is divided, so that one entry and one exit are made to maintain a circulating flow. The right end of elbow 1 504 is fixedly penetrated through circular plate 2 503 and circular plate 1 502 in turn and extends to the right side of circular plate 1 502. The right end of elbow 2 505 is penetrated and fixedly embedded in the right side of circular plate 2 503.

[0026] See also Figure 4 The large circular knife body 1 includes a tungsten steel layer 101 and a diamond coating 102. By setting the diamond coating 102, the strength and wear resistance of the large circular knife are improved to ensure the processing life of the tool.

[0028] To sum up: the high-strength large circular knife, through the cooperation of the cooling mechanism 5 and the channel mechanism 6, solves the problem that the inside of the large circular knife for rotating cutting cannot be cooled, thereby cooling the large circular knife as a whole. Instead, the cooling is performed by spraying coolant onto the surface of the large circular knife, which causes the surface of the processed workpiece to adhere to the coolant or be soaked.
