Technical notes
Notes from the shop floor: which tooth geometry suits which panel, how a worn edge reads before it fails, and what to measure before ordering a replacement blade.
When PCD diamond router bits beat solid carbide on a CNC nesting router, how to compare cost per linear metre instead of price per bit, and which flute geometry suits MDF, chipboard and melamine.
How to specify a PCD jointing cutter for an edgebander: the four dimensions that decide fit, Z2+2 versus Z3+3, which LEUCO part numbers cross to which machine, and when a cutter needs replacing.
What a clearing tooth does on a sawmill TCT blade, why 400 mm with 24 main teeth and 4 clearing teeth works, and what to send before a blade price can be quoted.
Follow the journey of a ZHONGJIAN TECH blade: steel selection, cutting, CNC grinding, heat treatment, hardness and flatness inspection, and export packing.
Marble, Dekton and concrete demand different diamond segments. Learn how segment design, bond hardness and cooling water affect cutting speed and blade life.
How to match circular saw blades to solid wood, MDF, chipboard and aluminum profiles - tip material, tooth count, tooth geometry and blade body explained.
Choose the right TCT or PCD circular saw blade for veneer, melamine and HPL panel cutting. Reduce chipping, cut without a scoring saw and keep edges clean.
