The wheel body is usually made of an aluminum alloy material having light weight and good thermal conductivity, for example, aircraft aluminum 7075-T6, and may be made of steel or cast iron.
The cutting wheel rotates in the environment with soot and dust, the tipping paper tape is in long-term contact with the outer circumferential surface of the cutting wheel in a high-speed rotation state, the outer circumferential surface of the traditional steel or cast iron cutting wheel can generate phenomena of abrasion, corrosion, dirt adsorption and the like, and further the phenomena of change of the outer circumferential dimension, blockage of air distribution holes, reduction of adsorption capacity and increase of operation noise are caused, and finally the quality of the tipping paper roll-connected filter tip is reduced, even unqualified products are generated. The ceramic material or tungsten carbide sprayed on the surface of the outer circle of the wheel body can improve the hardness, wear resistance and corrosion resistance of the surface of the outer circle of the wheel body, thereby avoiding the occurrence of faults such as size change of the outer circle, blockage of air distribution holes, reduction of adsorption capacity, increase of running noise and the like, further ensuring the stability of the quality of tipping paper rolling filter tips, effectively avoiding the generation of unqualified products and prolonging the service life of the shearing wheel.
