Ground Gears

As commonly seen grinding is most of the time thought in context of quantity fabrication of premium quality gears as a sort of secondary refining operation. We tend to forget that grinding is essentially a basic process in the step towards manufacturing case hardened gears. Moreover, the teeth of high-precision fine-pitch gears often totally ground from the blanks itself.

Advantages of Ground Gears
The Ground Gears offers specific advantages to its users. Some of which are listed below.

• High Precision
  Getting high precision is not a big task for Ground Gears as in the grinding process there is little removal of material in the final pass.
  
  
• Finer Surface Finish
  Grinding gives the Gears a surface finish more finer than that obtained from any other machining process.
  
  
• Added Flexibility
  It is possible to use hardened steel alloys to be developed into Ground Gears.
  
  
• Minimal Surface Stress
  There is minimal residual surface stress in case of Ground Gears.
  
  
• Load Carrying Capacity
  Ground Gears displays a superior load carrying capacity.
  
  
• Minimal Wear and Tear
  This reduced wear results in prolonged life for Ground Gears.
  
  

Limitations of Ground Gears
Though there are many advantages associated with Ground Gears, but they are not without any weakness.

• There is a limit to grinding operations and that is to ferrous metals.
  
  
• Hard metals can be grind in a better way than the soft ones.
  
  
• In case of helical or worm gears, grinding may not be the right solution. As it often involves deviations in terms of profile and removal.
  
  
• Gear grinding machinery is not so popular as hobbing machines.
  
  
• Grinding involves higher costs as it is a secondary operation.
