Taig Micro-Mill with HS Spindle

A video of my Taig mill with HS water cooled spindle running at 15,000 RPM milling wax double sided master for lost wax casting.  Sorry about vertical format. I know better but filmed this originally for quick share with a friend on  iPhone Messenger. Right click on image and open in new window for larger size and audio.

Tormach xsTECH Router

Tormach xsTECH RouterA first impression. My impression.  NOT a user report.

Note well:  It called a ROUTER not micro-mill. Or any type of mill.  Routers and mills are cousins, but don’t live in the same family group.

I was extremely excited when I saw this tool for the first time.  I like Tormach equipment and I especially like their Linux based PathPilot controller software. This little baby OH router, the Tormach xsTECH actually runs full strength PathPilot!

It’s also a complete, full house, tools and all, everything one needs to get up and running — 3-axis micro overhead router. WOW! Continue reading

Machining in the 4th Dimension

The fourth dimension is often mentioned in science fiction as a dimension beyond the human senses. Today, real scientists (if there are such people) claim the fourth dimension does exist. But there are IMHO plenty of pseudoscience, especially promoted as video “entertainment.”  Material for a future rant…

In machining there really IS a fourth dimension. Usually called the 4thaxis. The Hobbyist Machine Shop (THMS) has a fourth axis for use on the Taig micro mill. It’s been on both the mill used for metal machining as well as the wax milling machine. Currently it is on the Taig… Continue reading

Ring Carved on 4th Axis

Everything came together for the first real use of the forth axis mandrel for ring carving. It’s nice when the plan comes together and everything works as intended. There was of course far more than just making the mandrel. There is the CAD design stage and the CAM (Desk Proto) for generating the G-code for the 4th axis. Then running the G-code on the micro-mill. I use LinuxCNC and I had to write my own metric post processor for Desk Proto. Not all that hard, actually. I made a USC (inch) version too. One tiny code change.

The first picture… Continue reading

DeskProto for 4th Axis

Using 4 axis milling, requires a CAM software system to create the necessary CNC G-code. It’s not something one can easily hand code when doing 3D designs. Simple level surfacing could be hand-coded on a 4thaxis, but probably lathe turning would be far easier.

Aspire, a three-dimensional CAD/CAM produced by Vectric can produce G-code for the 4thaxis. It is one of my go-to programs. However, I don’t design everything in Aspire CAD. Fusion 360 and RhinoCAD are also programs I use for design.

Both these programs have 4 axis CAM built in. Fusion 360 has a… Continue reading
