we can make the following gears , gear grinding can achieve Grade 4-5 in Chinese standard, gear hobbing can achieve Grade 7-8.

we can make the following gears ,  gear grinding can achieve Grade 4-5 in Chinese standard,  gear hobbing can achieve Grade 7-8.   lots of our gears are exported to Japan and the US.  

1.  internal gear

     OD<2000mm

     modulus<20 

2.  external gear shaft

     OD<1600mm

     modulus<18

3.   spiral bevel gear

     OD<850mm

we prefer to do the gears which require surface quenching treatment(achieve HRC42-48) or carburizing&quenching treatment(achieve HRC58-62).  

we also hope to do gears which require surface grinding.
