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

Swarf Blower Added to Taig HS Spindle

Wax swarf blower system

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.

Taig 24K RPM Spindle Article Available

The full article on the Taig 24,000 RPM water cooled spindle conversion is now available on The Hobbyist Machine Shop website. Follow this URL:

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 use because of their extremely quite operation.

The Taig spindle is known for its quiet operation and the water cooled spindle here is in my opinion just as quite or perhaps more so, even running at full speed. Tool cutting sound is the same but the spindle motor has none of the sound of a high speed router.

Just Add Water

The water cooling has been added to the high speed spindle through the red tubes in the picture. This is phase one where I will be using a reservoir with a sump pump behind the bench.. This should let me operate for maybe an hour or so. I don’t have any idea how much and how fast the water will warm.

The next step in the water cooling will be to add a closed loop system with a radiator to move the heat out into the ambient air rather than store it in the water tank. But first I need to determine through running and testing how much heat per hour is produced by the spindle in my type of operation.

I will be in the 10K to 24K speed range for many hours of continuous wax milling. I suspect spindle loads will be very low but only through running and testing can I design an adequate cooling radiator system.

Next is the spindle three phase wiring and power connection, followed by programming the VFD. If all goes well the spindle should be operational in a few more days.

24K Spindle Progress

The parts arrived yesterday. Exactly as shown in the previous post. I placed an order for some four conductor cable for the wiring between the Variable Frequency Drive (VFD) and the spindle motor.

I needed to see the clamping size of the spindle’s electrical plug connector. I didn’t want to select and order a cable that would not fit. The cable is on they way to me, so I created the adapter I needed to mount the new spindle on the Taig Micro-Mill.

The picture shows the results of my work as the spindle is now nicely mounted on the mill.

After I am finished with all the mounting, wiring, and set-up… and I have the new spindle working, I will write a detailed report on the mounting plate and all the work required in making the conversion.

I think the spindle looks like it belongs on the Taig!
