Kennametal has introduced its next generation 3D printed stator bore tool for the machining of aluminum engine housings for electric vehicles. This latest version of the tool features a newly designed arm structure, a larger center tube made of carbon fiber, and a further weight reduction of greater than 20 percent over the original design.
The honing of gears - by definition
- facilitates ease of operation, low noise and smoother performance in a transmission. Honing also contributes to
reduced friction in the powertrain. Both the intense cutting (roughing process) as well as the functionally fine- finishing of transmission gears can be performed in one setup, on one machine.
Stringent NVH requirements, higher
loads and the trend towards miniaturization to save weight and space are forcing transmission gear designers to increasingly tighten the surface finish, bore size and bore-to-face perpendicularity
tolerances on the bores of transmission
