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.
It’s been a while since I have run my original CNC Taig Micro-Mill. It’s the one configured for metal work and has the mist cooling installed. There is nothing operationally wrong with it as far as I know. Just haven’t had a project where I needed its services.
I have always used RhinoCAD (Rhinoceros) with RhinoCAM to generate the design and the Gcode necessary to run the mill. I am presently working with FUSION360 CAD with its built-in CAM. FUSION360 has become my go-to CAD for 3D printing because of the very good built-in… Continue reading
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
