Here in the RD workshop, consideration is being made on adding a one horsepower 24,000 RPM spindle to the Taig CNC Micro Mill. The standard spindle is a belt drive one quarter horsepower unit with a top RPM of 10,000.
The standard spindle and drive is quite adequate for most of the milling work the micro mill is asked to produce. The primary use for one of my mills is wax carving with as small as 0.003-inch milling bits. That size mill bit can best operate at the 20K RPM and higher ranges.
I did some comparison of speeds and… Continue reading
I am presently using two very good 3-dimensional CAD programs. They are Autodesk Fusion 360 and Robert McNeil & Associates Rhino3D. I am at a decision point on which one will be my standard go-to drawing program.
I have had the longest association with Rhino. I started with version 3 and version 6 has just been released. Major version number upgrades must be purchased. That’s why I am at a decision point.
Fusion 360 is free for users like myself. That is a major advantage. The Rhino3D upgrade is $375.00.
It seems like a no-brainer to stay with the… Continue reading
I try not to go on guilt trips. The view is depressing, and it doesn’t solve any problems if I am busy blaming myself. I can be guilty of many things, but I don’t have to ride the train… Uh, oh… speaking of trains. That reminds me…
I am guilty of putting my live steam and model trains fun on the back burner. Heck, there are a lot of things back there, just simmering. Some of them may be stone cold… Well, that’s the way it goes. I can’t feel guilty about not being able to eat… Continue reading
Some progress is better than no progress. I have the desire to be back hacking metal parts, but I can’t get my body to do what my mind desires. It’s not a physical thing. Just switching mental gears from what I already do and getting to other things I love to do. I have way too may interests and options. I thought retirement would give me more time. Boy, was I ever wrong!
Choosing Proper Machine Way and Screw Lubrication.
I have always used a 20 weight non-detergent oil on all my machine tools, which is packaged in small cans for the lubrication of electric motor bearings. I apply it on the ways as well as the screws and crank bearings. I did not know what Taig recommended for the new ball-screws and bearings.
I contacted Taig and a staff person gave me… Continue reading
