fuel economy advantage extra gears might bring. The fi rst application of ZF’s 9HP transmission will be in models of the Range Rover Evoque with four-wheel drive. “There is no hard line, but you have to consider the law of diminishing returns. The question is whether adding even more gears makes sense,” he told the Automobilwoche Congress in Berlin in November 2012. Yet even before he spoke a press
report claimed that Hyundai was developing a 10-speed automatic. Also, a month before the Berlin event word circulated that Ford and General Motors had signed a memorandum of understanding to develop nine and 10-speed gearboxes. The two US au- tomakers had previously collaborated on six-speed automatics, and GM has confi rmed that the companies are hold- ing discussions.

The FVM-4034DCL easily tackles your BIGGEST projects. The double- column bridge machine not only offers BIGGER capacity, but has an automatic angular head change and horizontal and vertical automatic tool change. The machine is perfectly suited for machining BIG parts with a 5-face machining application.
The FVM-4034DCL also features these BIG benefits:
• The 90-degree angular head allows the spindle to shift from a vertical to horizontal direction and can machine more complex parts. The automatic head exchange simply performs with an M-code control that dramatically eliminates machine down-time.
• The oversized column and box-type beam construction provide better support and damping. And the 400 x 400mm RAM design on the Z-axis provides the machine with excellent support during the cutting process.
• The heavy-duty roller guide ways adopt a XYZ-axis, providing better acceleration and preventing a stick-slip problem. And the FVM-4034 not only handles the BIG jobs, it does it with cutting-edge control. The FANUC 31i control comes with an AICC high-speed machining contour control has a smooth 3-D interpolation contouring control and an optional 200-block look-ahead function.
Think BIG. Call your Chevalier dealer today to learn more about the FVM-4034DCL.

Whether the proliferation beyond nine-speeds is truly ben-
efi cial in providing improved fuel effi ciency or whether it is a marketing ploy for car companies to brag that “Mine’s bigger” remains to be seen. ME
