Profile Grinding of Large Gears

Increasing material removal efficiency through advanced infeed strategies

Profile grinding is the hard-finishing process of choice for large gears with demanding requirements regarding load transmission, running smoothness, and complex tooth modifications. No other hard-finishing process offers a comparable level of flexibility across such a wide range of applications. Profile grinding can be applied to very small as well as very large gears, to external and internal gearing, to involute and non-involute tooth forms, to components with and without interfering contours, and to both simple and highly complex tooth modifications. Furthermore, profile grinding allows the achievement of excellent quality levels that cannot be attained by any other hard-finishing process over this broad application range.

Inspection

For precision measuring, skilled machinists, toolmakers, and inspectors must have accurate tools and gages, produced from quality materials, carefully manufactured, and rigidly inspected, to ensure lasting dependability. Gages have evolved throughout the years beginning with mechanical, then electronic models, and now convenient wireless electronic versions have come on the scene. Each type has an important place in today’s quality control and inspection processes.

Heat Treating

Gas carburizing has been around for a long time. One could argue that gas carburizing is the most common heat treating process. Heat treaters performing gas carburizing are often characterized by a dirty environment, hazy surroundings, and that “smell.” While the product quality may be acceptable, gas carburized parts do come with some challenges, like excessive intergranular oxidation (IGO) or intergranular attack (IGA), which is often ground off. Low-pressure carburizing (LPC) has proven to be a much cleaner and very capable alternative process. Most furnace companies have combined LPC with high pressure gas quenching, which moved carburizing from the dark back room to a relatively “clean room” environment. However, there is still a strong need for oil quenching, which is the common feature of the long used standard integral-quench (IQ) furnace.
