Carbide bed knife advantages:
1.Unparalleled wear resistance
This is the most prominent advantage of cemented carbide. Its hardness is far higher than any other tool steel (HRA can reach around 93, far exceeding HRC 60 steel). When cutting highly abrasive materials (such as fiberglass-reinforced plastics, carbon fibers, and highly filled materials), its service life can be dozens or even hundreds of times that of ordinary steel bed cutters. This significantly reduces the frequency of blade changes and downtime.
2. Extremely long service life
This is directly due to its extremely high wear resistance. While the initial purchase cost is high, its extremely long service life means lower per-process costs and higher productivity, which is ultimately more economical in the long run.
3. Excellent compressive strength
Cemented carbide resists deformation under extreme pressure and maintains extremely high dimensional stability, ensuring precise cutting gaps and consistent cut quality.
4. Moderate corrosion resistance
Its chemical stability surpasses that of ordinary tool steel, making it more resistant to corrosion from certain plastic additives or chemicals in the machining environment.
