Specific embodiment
As shown in Figs. 1-5, a kind of device carrying out overlaying processing for mine excavator centerpivot, including cutter hub 1, circle
Pipe 2, support 3 and cutting fluid feed mechanism, the round tube 2 are mounted on the feed change unit of lathe by the support 3, the cutter hub
1 is mounted on the front end of the round tube 2, and the cutting fluid feed mechanism supplies cutting fluid from the rear end of the round tube 2；
The cutter hub 1 includes knife rest, positive blade 8, opposed blade 9 and feather key 10, and the knife rest is tube body, the knife rest tail
Portion is equipped with external screw thread 13 and the front end of the round tube 2 is screwed together；The front end of the knife rest is circumferentially uniformly provided with four knives
Pad 7, intake chamber 11 and rhone 12 are equipped in front of each edge bearing 7, and the intake chamber 11 is located at the inner wall of the knife rest, institute
The outer wall that rhone 12 is located at the knife rest is stated, the width of the rhone 12 is three times of the width of the intake chamber 11；Two
The feather key 10 there are two being set on the outer wall of the knife rest between a rhone 12；One of them described edge bearing 7 is set
