Video: Two Types of Gear Grinding


Gear grinding is one of the ways in which we finish the gears we produce at True Gear. We use grinding to remove surface materials on a gear blank through abrasion. This process uses friction between a rough surface and a piece of metal at high speeds to scrape away the material that is not needed in the gear. In gear grinding, small pieces are removed without affecting the overall integrity of the material. Depending on the technique we use, gear grinding ensures the proper creation of the gear’s teeth from the gear blank.


We use two different types of grinding to bring our gears to the perfect finish for you here at True Gear. These are form grinding and generating grinding. Form grinding is a gear grinding technique that is also called non-generating grinding. In this grinding technique, we use a disc wheel to grind both sides of the space between splines simultaneously. Attached to the wheel is an involute form to guide the grinding process.


We also perform generating grinding. This gear grinding technique is a straight-sided, meaning the gear moves along the abrasive tool to form the splines.


After the formation of the splines, the gear grinding process is still not complete. A final polishing process takes place, which perfects the grinding of the gear. Instead of forming the splines, polishing smoothens out the face of the gear. In this process, a polishing wheel is used to make the surface of the gear bright and shiny without any imperfections.


Gear grinding is basically the process of creating the teeth or splines on a gear. At True Gear, we make sure that our grinding processes stick to tight tolerances with the highest precision foe each of our customers. Every gear we produce is ready for action immediately.
