CNC 4th Axis Update

The Taig CNC mill is closer to having its 4th axis operational. All that is really needed is to get the wiring completed. The tail post is not mounted where seen in the pictures. I was making adjustments to the height. You can see it is easily adjustable.

I will bolt down the tail post once I have an application where I need to use it. I now have the shims I need so a couple of bolts in the base and I’m in business.

When I have it running I’ll post a SHORT video to prove… Continue reading

Small Ideas

I see I keep writing about one topic over and over again in my forums and blogs. It has to do with the size of the machines I enjoy using in my hobby. I keep repeating myself because it just feels so good to me in the choices I have made. Of course I am pushing my personal preference and that certainly doesn’t mean nor do I intend it to mean that my personal preferences are anything but personal.

If the reader doesn’t like my preference, I am not here to make a convert to my way of thinking. I… Continue reading

4th Axis on My Taig

I did a lot of research on how to implement a forth axis on my Taig CNC mill. I had some wild ideas not to be discussed here <grin> but that is the enjoyment of thinking outside the box. In this case the box is a pretty good one so I finally dropped back into the conventional world.

The screw drive of the standard rotary table has a lot of benefits in this  4th axis application. There are a few limitations in the area of backlash (controllable) and rapid speed (not really necessary.)

With small mills like the… Continue reading

Thinking Small for 2012

I am investigating very intently the world of very small CNC machining. I am looking at small items such as mold machining for model parts and jewelry sized items using very small milling bits and high speed spindles. Actually I should call it CAD/CAM/CNC. It is far more than running the CNC mill.

I also looked at micro machining but that is a very high tech world that is still outside the needs and abilities (and machinery) of the personal machinist. It is truly amazing what can be done in the very tiny micro machining. I am not going there.… Continue reading

G-Wiz(ard) Wax

I had the chance to use the GWizard tool this weekend. I have been working on a wax mold project and thought it would be a great opportunity to optimize my speeds for milling wax.

There is no wax material guide in the tool but there is two kinds of plastic listed, both hard and soft. At first I thought soft would be good but as I thought about how wax actually mills, it acts like a hard plastic with the type of chips it makes. Soft plastics kind of gum up and take special consideration in my limited experience… Continue reading
