Tool wear
The problems of overlapping deviation and misalignment of tooth tips and roots can seriously affect the transmission accuracy and noise level of gears. Tool wear during gear rolling leads to tooth profile "collapse" or "bulging"
-
Thermal deformation
The frictional heat generated during the machining and cutting process and the thermal expansion of the machine tool itself can cause thermal deformation of gears, resulting in a decrease in the profile accuracy and rolling performance of the gears
-
Roughness
Low cutting speed and excessive wear of the cutting edge can lead to poor surface quality, defects such as burrs and scratches, and even seriously affect the transmission performance of gears.

Chip removal and adhesion
Chip wrapping: Spiral chips block the sawtooth groove during carbon steel cutting, reducing cutting efficiency by 30% -50%. Chip accumulation tumor: During aluminum alloy processing, chips adhere to the back of the sawtooth to form a "cold weld", requiring frequent shutdown for cleaning
-
High cutting force
When cutting hard materials (such as stainless steel plates), the fluctuation of cutting force causes high-frequency vibration of the saw blade, and the saw blade wears out quickly
