Listen, You have to see this.
Here is a video of the Taig ER spindle running on the HB2. If it will not run in IE7 or IE8 browsers, turn off the protected mode. Microsoft has gone psyco on protection!
In the close up pictures the camera microphone was about 6 inches away from the motor. Note that the Stepper “tunes” are not drounded out by spindle noise. The farther away shots give a clearer understanding how quiet the Taig spindle operates. The cutting in this video was at 10,600 rpm and the travel was 50 IPM.
I love this operation and have a complete new spindle setup on order. Actually several. I also did some V-carving as a test. Works as expected as I have been running this setup on the Taig mill for several years.
Here is a picture of the finished carving. Two passes in 45 minutes. Nothing fancy, just some pocketing to give the HB2 a bit of a workout. This is not a keeper, but looks great.
