Efficient Turnkey Machining of Complex E-drive Components

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.

Variables to Consider for Broaching on CNC Lathes, Mills, and Machine Centers

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.

Broaching in the 21st Century

Back around 2005-2010, the most exciting things that were happening in broaching had little to do with broaching. What was happening - and continues to evolve today - was the emergence of on-the-edge CNC, software and servo drive technology. Together, they practically transformed a metalworking process as old as water into a viable, alternative consideration for producing high-volume part runs.

Innovating Against the Tide

During a year with a strong dollar, tanked oil prices and a number of soft markets that just aren't buying, one might expect spline manufacturers to be experiencing the same tumult everyone else is. But when I got a chance to speak with some of the suppliers to spline manufacturers at IMTS about how business is going, many of the manufacturing industry's recent woes never came up, and instead were replaced by a shrug and an "eh, business is doing pretty well."

The Broaching of Gears

Broaching is a process in which a cutting tool passes over or through a part piece to produce a desired form. A broach removes part material with a series of teeth, each one removing a specified amount of stock.

Cutting Tools Now

The cutting tool is basic to gear manufacturing. Whether it's a hob, broach, shaper cutter or EDM wire, not much gets done without it. And the mission of the tool remains the same as always; removing material as quickly, accurately and cost-effectively as possible. Progress in the field tends to be evolutionary, coming gradually over time, but recently, a confluence of emerging technologies and new customer demands has caused significant changes in the machines, the materials and the coatings that make cutting tools.
