New Generation VMC spindles

[gpettit]

Hi,

Getting ready to purchase a VMC and was curious about the new Haas Spindles.

Anyone using a machine with the newer 8100 inline spindle that comes standard on some of the new VF series machines? Just wondering how long they have been out and what people thought about them? Also looks like there is a 10k inline option as well with the same power. Are these the same spindles with different drives?

Thanks,

Greg

WallyL7 is on the right track.

The new generation of VMCs are based on the proven design of the 12k spindles. The 8k and 10k spindles are in fact, the same. The inline spindles have proven to be more robust and provide better surface finishes.

Here is an excerpt from the press release:

All Haas VF-1 through VF-12 40-taper VMCs are now equipped with a powerful 8100-rpm inline direct-drive spindle that is driven by a 30-horsepower vector drive system. The Haas inline system couples the spindle directly to the motor to reduce heat, increase power transmission, and provide excellent surface finishes. An optional 10,000-rpm inline direct-drive spindle is available for shops wanting higher spindle speeds. Both spindles yield 90 ft-lb of cutting torque.

Thanks WallyL7 and Ken, I am going to go with the 10k spindle.
