Integrated processing of lathe machining, deburring, heat treatment, finishing lathe, drilling, and tapping!
This sprocket is made from sintered metal (sintered alloy, powder metallurgy) and undergoes processes such as lathe machining, deburring, heat treatment, finishing lathe work, pre-drilling, and tapping. By dividing the processes into primary processing up to heat treatment and secondary processing after heat treatment, the main machining of the sprocket teeth is performed while the hardness is low, and after heat treatment, when the hardness is high and machining becomes difficult, only finishing work is carried out, thereby reducing processing time.

basic information
This sprocket is made from sintered metal (sintered alloy, powder metallurgy) and undergoes processes such as lathe machining, deburring, heat treatment, finishing lathe work, pre-drilling, and tapping. By dividing the processes into primary processing up to heat treatment and secondary processing after heat treatment, the main machining of the sprocket teeth is performed while the hardness is low. After heat treatment, the hardness increases, making cutting machining more difficult, so only finishing work is carried out, which helps to reduce processing time.
