I seldom, almost never make mistakes… HA! But I found one in my tool definitions for Vectric Aspire. Um… maybe I do make a few mistakes.
I use a very fine pointed, down to 0.003 tip tapered ball-end milling bits. Tapered ball-end milling bits are defined by their one side taper angle and the tip radius in… Continue reading
The blower that was added to the Taig spindle on the original WAX milling system has been updated to operate on the new high speed water cooled spindle. A full article with pictures can be found here: https://thehobbyistmachineshop.com/cms/projects/wax-fan-v-2-0
This is not a dimensional, How-To article. It demonstrates how 3D printing can be utilized to add accessories to the Taig mill and a high speed water cooled spindle.
The new spindle performance exceeds all expectations. It is not a low cost option / addition to an already adequate micro-machine tool system, but it does provide a very good way to achieve more than double the stock Taig spindle speeds.
Some applications using very small diameter tooling are performed much better when running adequate SFM and cut travel speeds. High speed spindles and especially water cooled ones like this example are a joy to… Continue reading
The new 24K RPM spindle has an ER11 style collet holder. Attempting to measure the TIR (Total Indicated Runout) is not possible with the measuring tools available at THMS. It should be well under 0.0004 inch.
With ER collets, TIR of .0006” (.015MM) is considered Class 1, .0004” (.010MM) – Class 2, and .0002” (0.005MM) is Class AA (5 microns). Of course, the cost increases with accuracy. Class 2 and higher is my recommendation. A holder with excessive TIR negates this accuracy.
The internal surface of the holder looks well finished. I am going to depend on the… Continue reading
The 24,000 RPM water cooled spindle on my Taig Micro-Mill is operational.
The power required to do wax milling with 0.004″ milling bits is extremely low. I use my old settings of 10,000 rpm and 10 IPM travel on the first run. The no load current on the spindle is 0.6 amps. While making the first carving the spindle ran at 0.6 amps. It was as if there was no load on the spindle motor.
The next run as shown in the video was at the recommended limit of the 0.004 inch tapered mill bit. The run shown is 15,000… Continue reading
