Efficient Turnkey Machining of Complex E-drive Components

Perfect E-Shaft with Integrated Production Solution

July 27, 2023

For the transmissions of electric vehicles to develop the desired high torque under all driving conditions, a very large gear ratio is needed, which requires high speeds. And to ensure sufficient momentum at all speeds and enable the driver to accelerate without shifting gears, the electric drive must achieve up to 15,000 rpm, which is about three times that of a typical combustion engine. This puts a lot of strain on the rotor shaft. The manufacturers of rotor shafts are thus facing new challenges, such as the significantly lower shape and position tolerances and the need for greater machining precision.

Broaching is an unusual machining process, because it has the feed built into the tool, which effectively makes it a collection of single-point cutting tools arrayed in a sequence. Analogous to the multiple passes of a shaper, a relatively new class of CNC tooling and programming allows broaching operations to be done without the need for a second operation, thus greatly increasingly quality control and reducing time, space and cost.
