For high-abrasion materials such as melamine and HPL-coated panels, solid surface materials, cement fiber board, fiberglass and CFRP, conventional carbide blades can wear quickly. Polycrystalline diamond (PCD) saw blades offer high wear resistance and stable cutting performance for demanding, high-volume applications.
PCD blades can be used on panel saws, beam saws, sliding table saws and portable job-site saws, including applications such as laminate flooring and cement board installation. For larger blades, body integrity is also critical because the blade plate must withstand the long-term load of highly wear-resistant PCD tips. The source material emphasizes the importance of both PCD tooling expertise and saw blade technology. fileciteturn8file0L19-L23
Nakamura offers PCD solutions for different materials and applications. The PCD Saw Blade for MDF is designed for panel materials such as MDF, HDF, particleboard and laminates; for abrasive cement fiber board, the PCD Saw Blade for Fiber Cement provides a dedicated solution; and for broader composite and abrasive-material applications, the PCD Tipped Circular Saw Blade is available in different specifications and tooth configurations.
PCD blades can also be professionally resharpened. According to the source, sharpening life depends partly on diamond tip height: a 6.5 mm Classic tip can typically provide up to about 12 sharpenings, while a 5 mm economical tip can provide about 6. Normal sharpening removes about 0.5 mm of PCD per service. Actual service life depends on material, equipment and cutting conditions.
For companies processing abrasive materials over long production runs, choosing a PCD blade should involve more than initial purchase price. Wear resistance, cutting stability, resharpening capability and total service life all contribute to the overall value of the tooling.
