The manufacturing method of diamond dressing gears for the dressing of gear grinding worms

摘要

The gear grinding process is a widely used process for gear finishing after heat-treated. The continuous profile grinding and the continuous generating grinding are the most common used gear grinding methods which have high productivity. The grinding worms can be dressing by diamond dressing gears, which have the profile of the workpieces to be machined and bonded a single layer of diamond particles. The paper has inroduced the traditional manufacturing methods of diamond dressing gears, positive electroplating and negative electroplating. Then put forward a new manufacturing method, Electroless nickel coating. Composition and condition of electroless composite plating solution, process steps are given. Several diamond dressing gears are made by this new method. Grinding experiment testified that it is an applied method and has many advantages.
