Abstract

The invention discloses a disc-shaped cutter pad and a manufacturing method thereof, and belongs to the technical field of machining of cutter accessories. The disc-shaped cutter pad and the manufacturing method thereof solve the problems that an existing cutter pad is low in machining precision and cannot meet the demands of high-precision parallelism and perpendicularity. A forging blank of the disc-shaped cutter pad comprises, by weight, 1.15-1.40% C, 0.40-0.65% Mn, 0.32-0.40% Si, 11.00-12.50% Cr, 0.90-1.40% W, 1.40-1.65% V, 0.70-0.95% Mo, 0.40-0.50% Ni, no more than 0.020% S, no more than 0.027% P and the balance Fe. The disc-shaped cutter pad is manufactured through the processes of annealing, primary machining, heat treating, coarse grinding, tempering and deep machining, and the heating speed in the annealing process and the heat treating process is controlled strictly. The disc-shaped cutter pad has the advantages of being not prone to deformation, resistant to wear and the like.

Description

technical field [0001] The invention belongs to the technical field of cutter accessories processing, and more specifically relates to a disc-shaped cutter shim and a manufacturing method thereof. Background technique [0002] Slitter blade design is a harmonious combination of slitter blade geometry, cutting material and coating. Only by continuously introducing advanced slitting machine blade design technology and promoting the development and use of new slitting machine blades can we meet the development needs of advanced cutting processing technology.
