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.
Platinum Tooling, the importer and master distributor of live tools, angle heads, Swiss machine products, knurling and marking tools manufactured by various international suppliers, will now carry REV broaching tools exclusively in North America.
Nidec Machine Tool Corporation announced today that it has launched Robot Camera SPEED, visual inspection equipment for cutting tools (hobbing machines) to process gears and other components, and Robot Camera MAX, visual inspection equipment for broaching machines.
