Manufacturing

 

  Forging:
 
100% Incoming inspection
(dimension test,hardness inspection,ultrasonic flaw detection)
 
Mark identification forging number and make traceability card to ensure all forgings controlled and traceable.
 
     
  Rough turning:
 
Lay a good foundation for fine turning, and strictly control the dimension and precision.
 
     
  Heat treatment:
Professional heat treatment processing equipment and technology to control the quenching layer hardness and uniformity.
 
     
  Tempering:
Eliminate the internal stress of rings during quenching, reduce the brittleness of hardened steel to ensure the strength, toughness, plasticity, elastic and other comprehensive mechanical properties.
 
     
  Gear milling&shaping:
High-speed gear milling machine and CNC gear shaper achieve the tooth accuracy and reliability one-time.
 
     
  Gear quenching:
CNC quenching machine tool can meet customers' various requirements of gear.
 
     
  Hole machining:
Imported CNC drilling machine, improve the machining accuracy and shorten the processing time of hole; Horizontal boring machine ensures the hole roundness, size and fit precision with ball plug.
 
     
  Turning&grinding:
Combining turning with grinding in one CNC machine to ensure final machining accuracy and reliability, reduce repeat positioning,improve work efficiency.
 
     
  Assembly:
Self-developed high precision assembly equipment controls the bearing assembly clearance, torque and operation stability.
 
     
  Finished product:
Every step of the production is carried out strictly in accordance with quality control documents,and equipped with a full set of quality inspection report. Inspector issues bearing assembly report,test record,and certificate according inner ring and outer ring traceable cards.
