Selecting appropriate material as customers' requirement of drawing and life-time of products.
Testing material chemical and mechanical properties.
Cutting material into appropriate pieces.
Ensure material reach right mechanical properties during following production.
Monitering size and controling temperature at any time.
6.Testing forging result
UT testing and size testing.
To refined crystal grain, uniform formation and residual stress relieving of material.
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.
Base on diffierent material of gears,heat treatment of the gear surface with different quenching process.
Ensure precision and finish degree pass muster of the quality and drawing requirement.
