INDEX TRAUB:  World Leaders in Precision Turning Technology

The revolutionary new R200 turn / mill center
The revolutionary new R200 turn / mill center

The new 65mm R200 Turning/ Milling Center produces precision workpieces nearly twice as fast as any conventional turn-mill. Two powerful 18,000-rpm milling spindles moving freely in the Y and B axes and two moveable 5000-rpm work spindles both rough-machine and fine-turn in two independent subsystems at the same time. And the R200 can do 5-axis work on both spindles simultaneously.

TRAUB TNL18 Swiss turning + Production Turning
TRAUB TNL18 Swiss turning + Production Turning

Quick and precise with a huge tool capacity: The surprisingly affordable TRAUB TNL18 is a sliding headstock automatic and a CNC single-spindle bar automatic in one.Changing over in only minutes, the TNL18 can put 3 tools in the cut at once, features a quick-positioning top tool turret with a larger tool capacity than any gang carrier--up to 24 tools--and chip-to-chip time of 0.3 sec. A counterspindle with large X/Y/Z axis travels includes a 7-station tool carrier, each tool can be equipped with multiple holders.

MultiLine:  CNC Multi Spindle Machines
MultiLine: CNC Multi Spindle Machines

The INDEX MultiLine combines the benefits of traditional high production multispindle automatics with the benefits of modern CNC technology.

The newest addition to the line is the affordable MS40, another member of the long line of leading INDEX multispindles featuring unmatched versatilty, quick changeover,and wide open work area for easy access and superior chip shedding. 

For nearly unlimited operations on small workpieces from bar up to 40mm or for chucking up to 120mm, the MS40 feratures six fully independent liquid-cooled hollow-shaft CNC spindle drives each capable of 7000 rpm. The MS40C can be equipped with up to 35 axes, 12 identical CNC tool carriers with 1 or 2 axes plus 1 or 2 synchronized spindles with 150mm travel in Z and up to 6 tools for backworking.

Investing in Technology Is a Strategy. Figuring ROI Is a Strategic Tool.
This short article by Jeff Reinert, president of Index Corp., outlines the multi-step process for justifying an investment in the latest CNC machining technology. Calculating the return on investment (ROI) is a useful step in this process, but only one of the factors a manufacturer must consider in the decision to buy a new machine. Read the article here.

Automotive Industry is Booming in Germany
Before heading off to Esslingen, Germany (near Stuttgart) to help Index celebrate its 100th anniversary, my publisher told me that the area is “the Detroit of Germany.” I soon found that to be an apt description as a large number of shops I visited were heavily vested in automotive manufacturing. What’s even more noteworthy is that business was booming.
