PRODUCTION PROCESS
1.Material
Selecting appropriate material as customers' requirement of drawing and life-time of products.
2.Material testing
Testing material chemical and mechanical properties.
3.Blanking production
Cutting material into appropriate pieces.
4.Heat treatment
Ensure material reach right mechanical properties during following production.
5.Forging
Monitering size and controling temperature at any time.
6.Testing forging result
UT testing and size testing.
7.Nomalizing
To refined crystal grain, uniform formation and residual stress relieving of material.
8.Rough machining
Lathe rough machining materials into homologous forging parts with rational margin.
9.Gear surface machining
Including CNC gear milling machine, gear shaper machine and gear slotting machine.
10.Heat treatment
Base on diffierent material of gears,heat treatment of the gear surface with different quenching process.
11.Finishi machining
Ensure precision and finish degree pass muster of the quality and drawing requirement.
12.Finished product inspection
Pitch inspection could be within 0.001mm, gear thickness inspection could be within 0.001mm, hardness inspection could be within 0.5ºC; CMM measure could be within 0.001 degree.
13.Packing and delivery
Packing with non-fumigation wooden boxes and steel tray, ensure products
