Any known contacts for MillMaster ?

Gorton is mostly dead. There is a company that may have some oddments thats partially owned by one of the family.

Hummm is that Mill Master or MasterMill? MillMaster is a Taiwan import built along the lines of your basic Bridgeport, but with a squared off head design, rather than the BPs rounded style.

If its a Gorton MasterMill..I have some documentation.

Hi Gunner,

I just recently realized that there are "Mill Master" and "MillMaster" milling machines out in the world. Ours is a MillMaster. Thanks for confirming that it's a Taiwanese job. I was told that the manufacturer was in the U.S.A. I'll try digging around the net some more and see what info I can find. I am basically trying to determine the proper type of spindle oil for the head. (The machine came to us without the lubrication plated that, according to the user's manual, is attached to the base of the machine.)

Thanks a bunch.

Just as a double check, look at the one on my website

and make sure its not a Gorton.

If its not..then just use the same lube that the Bridgeports use. Most fo the clones were pretty faithful, with the exceptions of some cosmetics (and material quality and fitting)

Lots of guys simply fill the cups with a good non detergent 30weight oil, or a synthetic.

Here is a bit that might be helpful

go down to the section that shows the and see where it tells you to put in the Lubriplate grease. Since the set screw is not marked on older machines..that part seldom gets lubed When you hear a rattly head ..thats the usual cause.

This is pretty common even on the clones.

If your machine is a variable speed head..at least once a week, run the speed up and down.

Hi Gunner,

Thanks for the useful web sites! Chips is a nice cat.

I have confirmed that our MillMaster is not a Gorton. Also, we have a varispeed head that looks very much like that shown in Fig. 10 on the its.foxvalleytech.com web site.

I have been trying to find what type of oil to use in the oil cups. The mill head can rev up to 4200 RPM. I was able to find spindle oil, from McMaster-Carr, rated for use either for 0-3600 RPM, 3600-6000 RPM, or greater than 6000 PRM. There is no oil that really matches the head's speed range. Fig. 12 that shows the lubrication plate for a BP is just what I needed to see. I had no idea that there are two sets of cups, each requiring different oil grades, nor that the grades are so vaguely specified.

Given all of this, and that out milling machine will be used for the occasional project, I figure that it would be safe to use the 0-3600 RPM spindle oil.

Also, thanks for the tip on maintaining the varispeed drive.

Regards,

Ross
