Carbide circular saw blade production process

1. Saw blade substrate inspection

1.1 Saw blade substrate thickness tolerance: ±0.01mm, (thin and multi-blade blade tolerance: ±0.01mm), batch thickness tolerance: ±0.015mm (thin and multi-blade saw blade tolerance: ±0.01mm).

1.2 Inner hole tolerance: +0.02mm. H7 or H8 standard, according to the requirements of the basic single plane runout: ≤0.05mm, (thin plate ≤0.03mm), batch plane runout: ≤0.06mm (thin plate: ≤0.04mm)

1.3 The hardness of the substrate is 44°±2 ° C, and the hardness of the sheet is 46°±2 ° C.

1.4 The surface of the matrix should not have black spots and rough lines.

1.5 Check for cracks and burrs.
