Precise Tooth Cutting

After heat treatment, the HSS saw blade blanks are fixed on high-precision CNC gear grinding machines. Ceramic-bonded diamond grinding wheels grind the edges with micron-level precision according to preset parameters. The feed rate and pressure are strictly controlled to ensure the accuracy of tooth angles, while coolant is used to dissipate heat and prevent deformation. After each round of grinding, non-contact measurement by an optical detector is carried out. If the error exceeds ±0.01mm, an automatic correction process is triggered, resulting in sharp and evenly spaced tooth profiles.

For the precision tooth profile cutting of TCT saw blades, the carbide tips are first fixed to the substrate through laser or high-frequency welding. Then, a five-axis CNC gear cutting machine uses CBN (Cubic Boron Nitride) cutting tools to carry out segmented processing according to the material characteristics: when cutting the carbide tips, a low rotation speed with high feed rate is adopted to prevent chipping, while the speed is increased for processing the substrate to improve efficiency. The dynamic balance monitoring system controls vibration in real time. Finally, electrochemical polishing optimizes the surface roughness to Ra≤0.8μm, endowing the saw teeth with both excellent wear resistance and smooth cutting performance.
