In the above-mentioned online repair track finish milling cutter disc, a rubber pad arranged in a regular hexagon structure is arranged between the first fixed groove and the fixed seat.
In the online repair track finish milling cutter disc, a disc-shaped gasket is arranged between the through hole of the cutter grain and the screw.
In the online repair track finish milling cutter disc, the square flat key and the cutter seat are fastened by two obliquely-installed screws II, and the square flat key and the cutter disc body are fastened by screws III.
Compared with the prior art, the online repairing track finish milling cutter disc has the following advantages:
1. compared with the regular hexagon fixing seat which is only used for fastening by a screw and is propped against the side surface of the cutter seat, the fixing seat which is arranged inside the cutter grain and the cutter seat and is additionally provided with the structure can further fasten the cutter grain, so that the cutter grain is not easy to slightly rotate in the cutting process, and the milling precision is improved;
2. vibration generated in the cutting process of the cutter particles is buffered through a rubber pad arranged between the fixing seat and the cutter holder, and the cutter particles and the cutter holder are tightly fixed through a disc-shaped gasket between the cutter particles and the screw, so that milling precision is further improved.
