Halfnutz, I found my high speed spindle solution. Or I should say KDN Tool found it. I wrote it up on 8-2-06 in Benchtop Mills titled - High Speed Spindle for SIEG X2 - I found it.

8-2-06 "High...

Bob Warfield, from the picture you posted, it would seem that you are actually machining multiple parts. Is that a setup to expidite set up time to make a succession of parts? Yes, each 5C collet...

Dave (dammachines), thanks for the heads up on the Tormach. Since they are using the Proxxon IB/E as their high speed spindle option - it has to be good. Bob Warfield, I'm still getting my machine...

I wrote up a post "High Speed Spindle for SIEG X2 - Getting Technical", well I found the spindle.

Looking for an affordable high speed spindle for your SIEG X1, X2, or X3 - or for any bench...

Daedalus, I contacted Ken at KDN Tool and asked him about the ball screws that are in my conversion. The following is Kens reply.

"The ball screws are actually a transport grade with .004"/12"...

Daedalus, I made a mistake on the KDN Tool web site url. It should be www.kdntool.com, the e-mail address is [email protected]

Daedalus, I just had my SIEG X2 mill converted to CNC. I was looking through the bench mill posts and saw yours. I studied the specifications of many of the commercially sold CNC mills before...

Daniel, thanks for your answers to my second question. I appreciate the timely response and depth of detail. I've been so busy though, that I have not had a minute to devote to my new CNC mill...

Daniel, thanks for the reply on Sept 6th. I started work again and have not had a chance to internalize your response till today. It would be useful if we colud pursue building a star. I am...

I was surprised to find that since the 1960s, when I worked as a Manufacturing Engineer, that a new technology has revolutionized the machining industry - high speed machining. ...

Developing your own solution is the way to learn. Functional analysis of the main functions - motor, spindle, and controller will uncover the pros and cons of a concept. You...

Hello Daniel, as you know I have just purchased Virtual Sculptor. I have no experience with any CAD or CAM software. Also my newly converted milling machine is in the process of getting setup. So...

Thank you for taking the time to help me get back down to earth. The cost to "reliably" get to 20,000 rpm, and the consumables cost for the bits I will be burning up don't add up.

When I wrote up the subject of this thread I made a mistake. The mistake is in the calculation of the scoping torque required to engrave brass. The error is in my selection of the feed per tooth. ...

Thank you for the free Alibre Design Xpress software. Everything downloaded perfectly, and it seems that you have added a new display on loging in to help people get started. Also, I have...

Kevin, I am having my MicroMark MicroLux Milling Machine #82573 converted to CNC. The machine is a SIEG X2. You are interested in a SIEG X3. KDN Tool & Automation Engineering Co is...

The thread contributors came up with a lot of...

I forgot to post the url for:

"The next site contains speeds and feeds specifically for end mills, by diameter from 1/16" through 3", for premium cobalt high speed steel, and regular high speed...

To the people that have responded to my post. As I've mentioned, I finally realized that "high speed spindles" are a subset of "high speed machining". And that "feeds and speeds" have changed...

Tokyocrow, here are some speeds and feeds referances.

Tokyocrow and Jon, you are right, an "engraving" tool is removing very little material, so high speeds can be used and still be within the chip load requirements of the tool. Yes carbide burs can be...

Halfnutz, I've looked into the air motor approach to high speed spindles. It looks like a great idea. To generate the CFM (cubic feet per minute) air flow for the required torque, a good size air...

Tokyocrow
I looked into the CNCMasters idea you suggested. It looks like a router solution. Also I've continued researching "high speed spindles". They can be deadly. At speeds even as low as...

JRouche, thanks for the idea. Turns out that is what KDN Tool & Automation Engineering Co. is doing for me right now, as a part of their CNC retrofit to my SIEG X2 MicroMark MicroLux Milling Machine...

Tokyocrow, youre right. Here is the pricing. Thanks for the great information.

High speed spindles are complicated and pricy, as I've learned. KDN Tool & Automation Engineering will provide a belt drive for my MicroMark MicroLux #82710. KDN Tool & Automation (www.kdntool.com)...

Rustyolddo, I just ordered one from Little Machine Shop. It's meant for the SIEG mini lathe models. Although I don't know why. They come with a digital tach readout. Maybe the older models...

Halfnutz, perhaps KDN Tool & Automation Engineering (www.kdntool.com) at [email protected] would know. They specialize in CNC conversion of the SIEG X1, X2, and X3 mills. They are in the process of...

The SIEG X2 Milling Machine is sold by MicroMark. It is called the MicroLux #82573.

I am in the process of having a SIEG X2 mill, sold by MicroMark, the Microlux #82573, converted to CNC. The conversion is being done by KDN Tool & Automation Engineering Co (http://www.kdntool.com)....
